A funny thing happened on my way to work one day, many years ago. I worked in a clock making factory, owned by my father. One morning on my way to work, I was listening to the radio in my car, and the topic of metric time was the conversation. I must have come in to the show some time in the conversation. I heard, that we will have 20 hours per day, so many days per month and so on. I was on to this, and as soon as I arrived at work, with this new information ready to blurt out of my mouth in excitement. Dad was having a chat with the other workers, when all of a sudden, I expelled this new found information to the group. Dad, did you hear, that we are converting to metric time. We should jump on this straight away. We need to work out the gearing for the clock movements. Silence took over the room. A glare from my captive audience. Dad looking amused at what had just taken place, and calling me out for being an idiot. Do you know what day it is? Me, Dumb founded, Monday! Dad, it the 1st of April! April fools day! Me, red faced and about the size of a mouse.
Some years ago I used to write articles for a music magazine and for one April edition I wrote about the new metric keyboard that had 10 notes per octave and even showed a picture of one of the new keyboards. I was amazed at the number of people who contacted me during that month after further details - people in the music industry who really should have known better.
@@olsmokey 10 notes per octave? You're cracking me up!! And they called for further details? LOL Did none of them ask why they wouldn't be called "dectaves"? I'd like to see that picture though, you made me curious
Some trivia on this topic that you might like: Clockwise is the direction that a shadow moves around a stick stuck upright in the ground in the northern hemisphere. The theoretical circle traced out by the shadow can be easily divided into 12 sections with a compass. But dividing a circle into 5 or ten is not nearly as easy. Cheers.
Also: at solar noon, the sun shines from exactly south - hence, in Hungarian, the word for south and the word for noon is the same ("dél"), while the word for north ("észak") is similar to the word for night ("éjszaka").
It is easier to split a circle into 8 parts rather than 12. The compass aid including, as there we have the north, east, south and west and four in-betweens. Or, if we like it so, we can split it even further into 16 parts.
Calling a 10 hour clock "metric" is stupid, because having it 10 hours means redefining how many minutes an hour has - or worse: redefining how long a second is. *For all intents and purposes, a 12/24 hour time **_is_** Metric time, because it's measuring time in seconds - an SI unit.* Making the 10/20 hours clock doesn't make it "metric"; that's just decimalization. The Metric system is not (strictly) all about decimalization. Edit: BTW, minutes, hours and days are considered "metric accepted".
About the whole Unix time thing you talked about around 15:00. I would say it's niche in the sense that a lot of people don't know about it. But Unix time is used in all of your devices, every single app on your phone. All of it is Unix time. I'd say it's by far the most commonly used time measurement right now. It's just that it displays it to us in human readable format
Was about to say this (I was only a year late). Epoch is FAR from niche, it's used in almost everywhere because it's standard and every language can convert it to HR time.
@@holidayfish Capitalists: Write that down! Write that down! Edit: admittedly, it would double work hours too but hey... It's a joke, I shouldn't overthink it.
My father had a saying that says a lot about a persons work life. "Always remember that you are selling what you can't buy, and you don't know how much you have." I miss you Dad.
My dad was a watchmaker with a wicked sense of humour that belied his shy demeanour. When Australia adopted the metric system in 1974, my father joked with everyone at church that if they came in to his shop that week, he would give them 10% off their new metric watches. He was mortified when at least half the congregation turned up that week (including the pastor).🥴
One of the challenges of metric time is that it is inconvenient for shift work. You can divide 24 hours evenly into 2, 3, 4, 6, 8, or 12 parts, which works very well if you have 3 shifts (8 hours each) or 4 (6 hours each). Metric time can only be divided into 2 or 5 parts unless you use fractional hours.
@@arthurclement8656 There is actually little gain of using base 12 over base 10. In base 12 there is problem when dividing by 5 (and 10) that are also common dividers. So you basically exchange one for another and there is no actual gain. You choose what you can write - 1/3 or 1/5. Base 30 would be the closest one with actual gain - additional prime divider. And that actually don't matter as in modern world for calculation we use computer swhich use base 2 - even worse (and probably the worst base system) as there is only 2 prime dividers and both 1/3 and 1/5 would result in infinite sequence of digits. And as seen above for actual mathematics there is no problem writing various fraction of 3 using base 10.
@@ravensblade ... but 1/5 of 12 is just 2.4. Thats still a finite, rational number. 1/3 of 10 is not rational or convenient. 1/5 of 16 is almost identical to 1/3 of 10; 3.2 vs 3.33333333333 except one is far more precise.
what gets me about this thing losing weight, is it may have not been the weight itself that changed. It could be the magma flow in the earth. The height above sea level or the speed at which the earth spins or the mass of buildings added to the neighborhood near by. Weight is too relative.
I was actually working in some software dev work at my university during the year 2000. I actually had to fix a bug in some code, because it had the every 4, except every 100, but not the except every 400. It wasn’t a big code change, and was pretty easy, but it did require me to read and understand all about leap year maths.
I must be a genius by comparison to most programmers during the Y2K problem, because my software planned for it starting around 1980 and I just laughed at all the fools who didn't think of it from the beginning!
A point of trivia: When the IBM PC came out, IBM designed the computer clock circuit to work the same as their mainframe computers, so they chose to start their PC clock on Jan 1, 1900. 1900 was not a leap year, making the circuitry in the chip more complicated. When Apple produced their first computers, they designed their clock circuitry to start on January 1, 1904. This meant that the circuitry was simpler and cheaper, because every 4 years from 1904 through 2096 are leap years. If your old Mac is still working during year 2100, it will not be able to display Feb 29, 2100 correctly (unless Apple fixes it via software). And that is also why Microsoft Excel for the PC starts at date 1/1/1900 and Microsoft Excel for the Mac starts at date 1/1/1904.
@@jeffwells1255 Just a point, the Y2K problem was created by two things: 1) RAM and storage space was EXTREMELY expensive back when computers were first made, and programmers spent an extreme amount of time optimising programs to take up the least amount of RAM and space, and to run on the least amount of CPU cycles in order to to save money (back then, computer processing was MUCH MORE expensive than labor costs), and 2) most of these programs were not expected to still be in use in the year 2000.
@@ibnorml You forgot also to say that customers often complained about having 4 digits for the year, while they were used to use only two when handwriting... Also, most displays were pure text displays (i.e. fixed number of characters on screen, often 80x25 or 80x50 characters). Same for printers, very often limited to 80 characters wide, sometimes 120 when using "condensed" fonts. Therefore, "wasting" (irony inside...) 2 columns for an "useless" information was considered as a bad thing to do. But the digits, printed with graphical dots using TrueType fonts and followed by a currency symbol, located at the botton of the numerous Y2K bills changed this mentality A LOT.

A small mistake: meter was never defined as 1/1 000 000 of distance from pole to equator, you are missing one zero, 1/10 000 000 would be correct ratio.
Yeah, about that. A meter is the side of a cube of a mass of fresh water that weights the same as the average mass of a nautical ton which varies a little bit because any given localized 35 cubic feet of sea water may weigh slightly different amounts. The "ton" was already an international standard of displacement and to be accepted the metric ton had to literally be the same mass on a balance scale. Its kinda like how all shipping containers are actually based on the 24 or 48 foot size because of the international pallet standards and that the dominant accepting markets were still using feet. So the metric system is literally based off the foot.
I always thought it was because 12 is so conveniently divisible, so you can split the time on a clock into a lot of different sized chunks for scheduling, without breaking into individual hours. And when you do have to break apart hours 60 (a multiple of 12) can also be neatly subdivisided based on need.
Base 12 makes a lot more sense than base 10, except that we have ten fingers. Otherwise, I bet we would have evolved to use it for everything, including the metric system (a gross meter vs centimeter)
@@PhilipKaskela The issue though with base 12 is that it doesn't convert well into the standard Arabic numerals system that is used all over the world (because that's a base-10 setup). Now the old Sumerian system of base-60 definitely had significant advantages for complex mathematics, but it seems that asking modern man to memorize a base-60 system is a bit much. For some reason.
12 is such a nice convenient number, being divisible by 3 and 4. We kinda sorta counted some things in a base-12 system, I mean we still use the word "a dozen", meaning of 12 of something. And in many languages (including English) we have unique words for 11 and 12.
@@1985ThePedro Babylonian cuneiform numbering didn't simply have 60 symbols. It was more like Hangul in that each digit was composed from smaller marks. Here's what Wikipedia's Sexagesimal page has to say about it: "The sexagesimal system as used in ancient Mesopotamia was not a pure base-60 system, in the sense that it did not use 60 distinct symbols for its digits. Instead, the cuneiform digits used ten as a sub-base in the fashion of a sign-value notation: a sexagesimal digit was composed of a group of narrow, wedge-shaped marks representing units up to nine and a group of wide, wedge-shaped marks representing up to five tens. The value of the digit was the sum of the values of its component parts:" "Numbers larger than 59 were indicated by multiple symbol blocks of this form in place value notation."
@@ssokolow That's a good point. It isn't that it was exactly a base-60 system when you were only considering numbers below 60, but more that if you had a larger value you would end up with less places than in the Arabic Numeral system commonly used today. The Arabic Numeral system is also far superior to the Roman Numeral system for most number. Even though a number like 10 takes two digits for Arabic but only 1 symbol for Roman, most numbers in between become pretty labor intensive. And the math is also often labor intensive, even though it can be done by someone who is less mathematically literate. The Babylonian system, with a value of 60 in each place, is even less labor intensive than the Arabic system, but does require a slightly more advanced literacy in mathematics to solve without excessive labor. All that aside, variations of Roman Numerals (tally marks, which actually are precursors to Roman and not necessarily a variation) are probably the best method for keeping a running tally of a grouping. It's thought that RN evolved as a way of managing larger sets of these tally marks, and that the disposition of symbols to subtract from a value vs add to a value was a later feature.
Here (NL) there was this guy once who went to the local 'people bring art to experts' show with a clock he believed was weird but rather well made. In turned out to be a French clock from just after the French revolution with the metric timescale applied. This was only a short period before the French went back. So the clock was very rare and woth about 150.000 euro.
Also, traditionally when a new king was enthroned, the units of length were restandardized. Thus, restandardizing a measurement system after a revolution made a certain sense.
@@shadowcween7890 I'd be cool with a binary system or hexadecimal. Baring those choices then dozenal is a good one though. Of course we'd probably want to change our daily math system for clarity.
You'd think that after removing a bad king from power, instead of removing his head, you'd remove his feet. Then he'd have to suffer the rest of his life watching his kingdom operate according to his successor's foot-length. Especially humiliating if that foot was noticeably longer -- wink wink.
That's very interesting, thank you. One of the factors was because the clocks and watches were cutting edge high tech back then. You could force people to change the scales and rulers but time devices were much more expensive. And it's not just adding metric marks on the inch ruler. You have to re-engineer and rebuild the clock from scratch.
I saw an interview once with the guy at Microsoft who led the team that kept track of the world's time zone's, DST dates, stuff like that, to make sure instances of MS Outlook all around the world agreed upon identical times and dates for a given appointment. I can't find the video anymore (it must have been 10+ years ago) but I remember him describing the nightmare this job essentially was. This team had to browse like Chinese regional newspapers to find out that some province would switch time zone to match a neighbouring province, or discover that Chile is going to change the date at which DST becomes active. Making mistakes, or missing such changes, meant Outlook users missing appointments. Outlook users not updating their Office software could mean the same. Surely an interesting but frustrating job, and one that will not have changed much. (if someone can find this video, if it's still up, please let me know! I'd love to rewatch it)
This reminds me of a quote from one of my favorite books "Once second is defined as 1/100,000 of a solar day on Home. One meter is defined as 1/300,000,000 of a light second One gravity is defined as 10 meters per second squared acceleration. The Emperor has decreed that the speed of light shall remain as nature has provided." It always cracks me up how generous the Emperor was not overriding the physical constants. Anyway, the book is Risen Empire by Scott Westerfeld, great hard Sci-fi.
Before age 50 I didn't think of time. Now it's my most valuable resource. I used to fix everything myself, now i pay others to use my time remaining wisely. The 2011 movie "In time" really hits home.
A little trivia. As you mentioned, the meter was defined originally as "one ten-millionth of the distance from the North Pole to the Equator", which was actually measured from Dunkirk to Barcelona. The commission to measure that distance was signed by Louis XVI on the morning of the day the mob attacked Versailles and took Louis prisoner. Also, it turned out that the measurements were wrong, which they tried to correct a few times. But by that time someone had put the scratches on the platinum bars. They didn't want to erase the scratches, so they ignored the measurements and just went by the scratches.
The group land surveyors left Paris to go out and start measuring, but they actually had great difficulty getting out of the city gates, since their pass had royal seals on it, and the guards were of the "new regime" (non royalist). If the head of the group who took the measurements would not have been persuasive enough, the group would not have been able to start measuring at all.
"They started it in September of our Gregorian calendar because... I don't know why" Well it would have been easy enough to find out. It's because the Republic was declared on the 22nd of September 1792, which became Year I of the Era of Liberty. All French dates were therefore traced back to that point.
And that's why it didn't work -- France was expecting the rest of the world (read: Europe and the Americas) to switch over to a calendar based on an event in French history. Zut alors!

When I was 15, we switched to decimal currency on 15 February 1971. As an April fools stunt, the local newspaper the Kentish Express ran a story that we were going to move also to decimal time. Each day would have ten hours, each hour ten minutes and each minute ten seconds. Not only did some people fall for it, many teachers wrote off for the imaginary info pack offered. Never trusted a teacher since.
There was the watch company Swatch, which created .beat time in 1998 dividing the day into 1000 beats. There were no time zones, and the day was based on the time in Biel, Switzerland. One of the few applications to implement it was the video game Phantasy Star Online, with in-game clocks and timers being set to it. For example, you could feed your "mag" (robotic pet) every 2 beats, though players usually just said 3 minutes. It also eliminated the need for international groups of players to convert time zones.

Time is based 60. That means it is divisible by 1,2,3,4,and 5. This means you can get finer resolution without decimals. It also means there are more places to introduce errors.
@@majorramsey3k yes, i only listed the prime numbers. Because we are so used to computers today, this is often overlooked. The imperial system also considers this.

Joe the number you said has the number of joules in a kg is actually Planck's constant. The number of joules in a kilogram by E=mc² is much much much much more than a fraction of a fraction of a joule. Got that thing wrong buddy
The kilgram was tied to Planck's constant (h) by defining h to be exactly that number in kg m^2 / s. Since the meter and the second are already defined by c and Cs ocillations, this gives us a fundamental kg.
I always use Unix Epoch time for applications I architect. A timestamp is the exact same time everywhere on the planet and doesn't get changed with daylight saving shifts. That means it can be delivered to a client device and converted to a human readable time based on the preferences of that specific client device. It's very useful.
@@thomasmaughan4798 That date is the limit for the 32-bit (signed) integer. We've been progressively switching to 64-bits for the past 2 decades, and this also apply to time representation. Most OS have already switched to using a 64-bit integer for storing the epoch; and the same apply to the now common and recommended file storage systems; Databases are on the same page, with the most common now handling epoch timestamps way past 2038. While some old programs and formats will probably break at that time, it's most probably not going to be a big deal.
I think it is also important to realize that as useful as decimalization is, there is also use to base twelve and base twenty, which the earlier systems included. Think of the number of gains in an ounce, 480. That is evenly divisible by 1, 2,3, 4, 5, 6, 8, etc.
This, also in connection with the loss of time due to the uniqueness of transience: Lying on your deathbed it cannot be otherwise that you are overwhelmed by a great feeling of loss and regret. Only your "past" contribution to this world can compensate for this. So nothing to worry about for you, Joe Scott, you will be remembered.

Time is measured in the old Babylonian base 60 math system. They charted the rotation of the earth by observing the motion of stars and the general progression of the zodiac. This same system is used today in angular measurement. The metric system works because it was incorporated into an already existing largely base 10 math system. I say largely because Geometry uses some of the old Babylonian system. What I find pretty cool is that we are able to use the current base 10 and the old base 60 system together.

It's actually not too surprising. If you examine the symbols (and hence the math), used for the base 60 system it is actually a mash up of a base 6 system with a base 10 subsystem using different symbols for the two bases. To be more specific, they used one symbol to count to 5 and another to count to 9. There was no symbol for zero. BTW, The Sumerians invented the base 60 system some 5000 years ago which was then later used by the Babylonians. Wikipedia and Google are your friends for further info.

Fun fact about the Julian and Gregorian calender switch: In the Spanish Netherlands, different provinces adopted it at different times, but there was very vivid correspondence between cities in different provinces. This meant that letters (which were always dated and included the date of the last letter sent in case the previous one didn't arrive) could arrive before the 'written date', or even include two different dates.

Thanks for the reference to VAX/VMS! It is pronounced like the first syllable in vaccine not as the individual letters. VMS is pronounced as the individual letters. VAX was the original Digital Equipment Corporation hardware platform that ran VMS but has since been ported to other platforms like x86-64. I'm one of the current VMS developers. That base date that VMS come from November 17, 1858 is the base of the Modified Julian Day system. The original Julian Day (JD) is used by astronomers and expressed in days since noon January 1, 4713 B.C. This measure of time was introduced by Joseph Scaliger in the 16th century. It is named in honor of his father, Julius Caesar Scaliger (note that this Julian Day is different from the Julian calendar named for the Roman Emperor Julius Caesar!) Why 4713 BC? Scaliger traced three time cycles and found that they were all in the first year of their cycle in 4713 B.C. The three cycles are 15, 19, and 28 years long. By multiplying these three numbers (15 * 19 * 28 = 7980), he was able to represent any date from 4713 B.C. through 3267 A.D. The starting year was before any historical event known to him. In fact, the Jewish calendar marks the start of the world as 3761 B.C. Today his numbering scheme is still used by astronomers to avoid the difficulties of converting the months of different calendars in use during different eras. So why 1858? The Julian Day 2,400,000 just happens to be November 17, 1858. The Modified Julian Day uses the following formula: MJD = JD - 2,400,000.5 The .5 changed when the day starts. Astronomers had considered it more convenient to have their day start at noon so that nighttime observation times fall in the middle. But they changed to conform to the commercial day. The Modified Julian Day was adopted by the Smithsonian Astrophysical Observatory (SAO) in 1957 for satellite tracking. SAO started tracking satellites with an 8K (non-virtual) 36-bit IBM 704 computer in 1957, when Sputnik was launched. The Julian day was 2,435,839 on January 1, 1957. This is 11,225,377 in octal notation, which was too big to fit into an 18-bit field (half of its standard 36-bit word). And, with only 8K of memory, no one wanted to waste the 14 bits left over by keeping the Julian Day in its own 36-bit word. However, they also needed to track hours and minutes, for which 18 bits gave enough accuracy. So, they decided to keep the number of days in the left 18 bits and the hours and minutes in the right 18 bits of a word. Eighteen bits would allow the Modified Julian Day (the SAO day) to grow as large as 262,143 ((2 ** 18) - 1). From Nov. 17, 1858, this allowed for seven centuries. Using only 17 bits, the date could possibly grow only as large as 131,071, but this still covers 3 centuries, as well as leaving the possibility of representing negative time. The year 1858 preceded the oldest star catalog in use at SAO, which also avoided having to use negative time in any of the satellite tracking calculations.
The idea of days of the week being counted in order kind of happens in Brazil and Portugal (and I believe that for other Portuguese speaking countries too): Sunday = Domingo Monday = 2ª-feira Tuesday = 3ª-feira Wednesday = 4ª-feira Thursday = 5ª-feira Friday = 6ª-feira Saturday = Sábado
When I was kid I tried to calculate metric time. This was mainly to aid in keeping time while out in space, long before I learned to the time space relationship with gravity. Anyway , my calculations were a mess trying to reconcile normal timekeeping with metric time. I only got as far as hours. Days, months, years could not be reconciled for normal relation. - Seconds are Base 10 - Minutes are 6*Base10, 10*Base6, or Base60 - Hours are 6*Base10, 10*Base6, or Base60 - Days are 2*Base12 or Base24 - Weeks are Base 7 days. Weeks are dropped from reconciliation as unnecessary. - Months have no Base varying from 28 or 29 days based on leap years mainly because a year ends in quarter day, and 30 or 31 day intervals. Months are then dropped from reconciliation. - Years are Base365. With no months, Base(months) can not specified. I was a kid (not even 10) and I'm sure I was close to hitting the nail on its head, but i think this was when math started eluding me for the more intuitive.

I can take really nice measurements of daylight and how long I sleep and when things happen! 1/2 = 50% 1/3 ≈ 33%, 1/4 = 25%, stuff i know well in decimal. Its been so nice! Im not sure how we ever lived with 24 hours a day 60 minutes... Etc. Especially when decimal seconds are a little faster, you get a finer measurement with them. ahh, im too lazy to switch back! Its just too nice.

@@igorfrancapereira4888 In Louisiana, there's still a number of people who speak French daily. And Spanish is the first (and sometimes the only) language for over 15 percent of the population in the USA, mostly in Texas in Southern California, which borders on Mexico. And I'm not even mentioning all the languages of the indigenous peoples in the USA, or all the languages brought there by immigrants who still use theirs within their communities, like Italian, Russian, Chinese, or even Yiddish. In fact, the USA has no official language (as in: codified by a national law.)
As a Spaniard living in a French-speaking country and married to a French guy, I confirm that trying Spanish accent makers the pronunciation more accurate than if he tried the English one. Also, this is an absolutely natural mechanism for people who speak more than one language: when you learn a third one, you apply to that one the accent of the second language (the one that you identify as "foreign"). I have French accent in German and Dutch, which is just ridiculous and confusing 😕
Most people never notice that Sept-Dec are named after 7-10 in Latin, since those were the seventh - tenth months until we added July and August to honor some kings.
It’s literally in the video that the change from julian to gregorian made the start of the year in January instead of March, which accounts for the mismatch in month names
Actually the Julian calendar used systematic names for months 5 and 6, before being renamed for emperors. The original Latin names were Quintilis and Sextilis, and if those names had survived, we could have Quintober and Sextember on our summer calendars! Even today's politicians monkey with time zones every few years. By the sun, each zone should be 15 degrees wide (360 / 24), with straight borders from pole to pole, but look at a time zone map of the world and you'll see the carnage.
11:28 it is also the same reason why there are 360 degrees in a circle rather than 100. Everyone was on the same page with that one. Although there is a system for that called gradians. There are 400 gradians in a circle. They would have to use the gradians system to create time zones if metric time was introduced. There is also the turn system. There are 100 centiturns in a circle. 1000 millieturns in a circle.

"Can anyone imagine the pain of having to sit through a Metric hour long meeting each week at work?" Obviously it depends on how long is a metric hour. Meters are length, not time.
10 decimal minutes = 14.4 standard minutes so…. 40 decimal minutes would be your equivalent to a 1 hour meeting and 20 decimal minutes would be your half an hour lunch break.. Working 9 to 5 would be equivalent as working 3.4 to 7.2 decimal o’clock 😅 Lunch hour would be the same as 40 decimal minutes at 5 decimal o’clock

I always thought that ... a system like that is something that we need. - 100 seconds in 1 minute. 100 minutes in 1h, etc. - 30 days in a month... seems ok. Although some of the other options you mentioned might work as well, but ... using our current month settings, just changing seconds, minutes, days and weeks, could work great. - Now ... since many places are trying the 6h shift (instead of 8h), or the 4 day week. We could, "EASILY", have a 10 day week, with a 3 day weekend (Fri, Sat, Sun), with 3 new names for days, and ... maybe a middle-week day off, as Wednesday or Thursday (it will depend on the arrangement between the individual and the company). - Such Idea, would give us a lot... A LOT!: > Easier ways to measure time, allow us for faster calculations, AND, saving time in our lives. > a 3-day weekend, helps with travelling. You could leave early on "Thursday" ... let's call it "Ragday" (for Ragnar, since, Thursday = is for Thor's Day), and ... catch a plane(or get into a car), and travel during Ragday (maybe even arriving on the same day), having Fri, Sat, and part of Sun to enjoy our trip, and the reminding of Sun to get back (and even rest). > Having a 10 day week, would allow to split the year into 36.5 weeks, which would allow us (more or less), to predict what day for a specific date (bi-annually). But at the end of the day ... I don't care about cultures, traditions, and superstitions. I would want a fixed system based on scientific thought. Let's have all the scientists, linguists, historians, etc. sit together and figure out a proper arrangement. Even if we move from the decimal to the duodecimal system, I'm onboard with it!.

I've worked 4 hour shifts, when you sail off-shore (ocean sailing, essentially). You do two a day of 4 hours each, 8 hours between each. It was law (maritime law). But (there is always a but): you could be worked OverTime during your off time. Of course it was "voluntary" O.T. Yeah, right. But, the Law also says a "watchstander" has to get 8 hours of uninterrupted sleep, every day, which can be split into 2, of which one sleep period has to give 6 hours of uninterrupted sleep, and the other 2 hours. So, there were 3 watches: the Mids, midnight to 4 AM (zero to zero-4 hundred) and Noon to 4 PM (12=-hundred to 16-hundred). There is the 4-8, both Am & PM. There is the 8-12s, both AM & PM. That's for "watchstanders". There are day workers (that includes "night"), with any number of schedules, but still 8-hours workdays. Or 12-hour days. That is allowed to vary, even day to day. Now, on Sunday, there is a rule left over from the sailing ship days called the "dog watches". You do some 2-hour watches so you change watches. That was so, on a long trip, you shared the misery or joy of each watch, didn't get into bad habits, etc. (Hey, the 4-8 watches have less supervision - which, with lousy or unpleasant supervisors, you get a break from them. But that was never an official reason: duh.) Only sounds complicated. Some "modern" companies, and some military vessels, no longer "dog the watches". It only sounds complicated. You get used to it. Now: In "protected waters", (The Inside Passage, certain rivers and lakes, the inter-coastal passage, etc.) you can stand 6-hour watches, 6 hours apart, for a 12-hour and no O.T. for that. So, you work an 84-our workweek, have a week off that's on shore. Or save them up for many weeks ashore. On my week-on-week-off trips, we were still considered "employed" on the weeks off, so still got benefits like Medical Insurance. Remember, we got 84-hours of work in one week, so that's two 42-hours worth of work. There was a different system for "vacation" on the sea-going vessels. Like I said, it only sounds complicated. (Yeah, right!) Heave Ho, me hearties.
@@TVfen "using our current month settings, just changing seconds, minutes, days and weeks, could work great." I may have read it in a way different than you meant but, to me it says it right here. The second is as arbitrary as the metre. Today a second is defined as ''being equal to the time duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the fundamental unperturbed ground-state of the caesium-133 atom''. Changing it would ruin quite a few mathmetical equations... and my work. Plz no...
I like the way you think, I wouldn’t mind to have 10 days weeks, 36.5 weeks year (One year with 36 weeks, and one year with 37 weeks). All this “time” notion is man made anyway… what would happen when we would have colonies on Mars (where the day length isn’t exactly the same). Days will drift, we would have to keep different calendar for each planets… and if Aliens come to earth, they would probably find this whole time completely stupid… and same with many other units anyway. That’s why it’s stupid to stick to units that don’t represent anything (like the Imperial system). And it’s better to define units using scientific measurements (like using Elements characteristics to define a man made unit).
To me, the biggest drawback of metric time is that you can't conveniently divide a day into fractional units other than 2 or 5. Imagine being the lord of a keep, or the skipper of a war frigate, and needing to set a watch rotation. You either have to have 5 shifts or 2 shifts, or else set partial hours, which defeats the purpose. 24 hours works much better, the more so even today with many more needs for shift work, when you can divide the day into 2, 3, 4, 6, 8, or 12 equal parts.
Honestly, this isn't really a problem once you use a complete metric system. This is the same excuse as I often hear for measurements, it's easier to split something in 12 parts... With metric system you can easily convert to smaller units. For example instead of 0,6 = 6 dm; 0,6 dm = 6 cm; 0,6 cm = 6 mm; 0,6 mm = µm; 0,6 µm = 6 nm... 1 m divide by 40 is too difficult? convert it to mm: 1000 mm / 40 = 25 mm A day could be 100.000 seconds or 100 kiloseconds (or if you change it to 1.000.000 seconds: one megasecond), and have the same duration as now if you adjust the duration of a second (but here's the biggest problem why we don't change it, all are technologies are simply based on our current seconds). And the prefixes aren't hard to learn: they are the same for everything. It's just the way of thinking that needs to be changed. There is a reason why we work with seconds in more advanced maths, and not hours and days.
This is exactly why the Babylonians handled time the way they did. They used a base-60 counting system, which gave them a lot of really nice numbers to work with, including multiples of 12. So to them, 24 hours in a day was a round number, in the same way that a 25-cent coin is a convenient subdivision of the dollar.
@@denjo3131 That doesn't solve everything. For example, how do you write a third of a meter? 333 millimeters is too small, so is 333 333 micrometers, so is 333 333 333 nanometers, and so on and so forth. No matter how finely you subdivide the meter, the third-meter will never have a nice representation in metric units.
Which is why we should use base 12 or base 60 instead of base 10. But it would be literally impossible to switch our number base unless we started like a small space colony or something.
@@denjo3131 I'm not so sure its a clean as you say regarding shift work. If the day is 10 hours long and you have three shifts, then two of the shifts must be 3.3 hours long and the third must be 3.4. I mean, you can get more granular, with 3.333 and 3.334, and you can introduce smaller units (e.g. 3 hours and 33.33 minutes) but there is no way to make it even. You lose one unit of time to rounding error (e.g. 0.001 hours). To gain what?
A day on Mars is roughly 40 minutes longer than a day is here on Earth. The people on JPL/NASA team controlling the new rover moves to Mars time, so family life will be a bit complicated the next 6 months.
3:19 we British use imperial as well. Well if you want to more precise we actually use a hybrid. To be More precise we are imperial / metric selective.
Having grown up in England in the late 70s/80s, I grew up with a mixture of both metric and imperial measurements, and indeed to this day, I use both depending on what's more convenient. If I'm reading a modern architect's drawing, measurements are almost always in metric, but the raw materials, such as timber, although now sold in strange metric numbers, are almost universally actually imperial. For example, a plywood sheet might be sold as 2440 x 1220 x 13mm, but we all know it's 8 feet by 4 feet by half an inch (and actually, they tend to more accurately reflect imperial measurements in any case). Metric measurements are easier to grasp, and I adore the interchangeability between measurements, but... It's not easy to divide evenly, 10 sweets between 3 or 4 children, but 12 sweets? Piece of cake. Lindybeige made a fab video about the divisibility of old pence (240 to the pound prior to decimalisation), but I confess, I still can't understand why shillings were ever a good idea.
In Germany we were meters really exclusively. Then Monitors came along with their diagonal being given in inches, a convention adopted from the Americans. Now even TVs are often measured in inches, when it was centimeters in the past. A strange step backwards.
@@cube2fox It has to be a marketing ploy of some sorts, i think. Maybe something sexy and easily graspable/comparable (monkey brain this number is bigger than that number level thinking) about those even numbers (consider 60" vs. 152,4cm). Because most germans have no idea how big an inch is.

Yeah. The idea was to have days off around the “Fête de l’Être Suprême” the yearly celebration of the Supreme Being, the non-denominational State religion to replace “religions” (i.e. king-supporting Catholics), to let more people come to Paris. There were a couple but it didn‘t work out so well because the whole thing felt very much new-king-same-as-the-old-pope, and the celebration was during harvest, so people stayed near the fields.
@Bozkurt postuna bürünmüş yobaz AraB devesi No. From the Wikipedia page for Sans-culottes: “The name sans-culottes refers to their clothing, and through that to their lower-class status: culottes were the fashionable silk knee-breeches of the 18th-century nobility and bourgeoisie, and the working class sans-culottes wore pantaloons, or trousers, instead.” en.m.wikipedia.org/wiki/Sans-culottes
Knowing french mentality, the "working more days in a week thing" is a big part of the problem. If they just changed hours, seconds and minutes It might have stuck.
My notion of a new calendar: every week is 9 days long: you take the last 3 off, and trade off on who is on their weekend. there are 4 seasons, each 10 weeks long; each season is ended by a special extra day. And every 4th year is the usual leap year day. The key interest is not having a single common fixed weekend for everyone, so activity is spread out.

The most logical calendar would be 13 months of 28 days each, with one month containing four 7-day weeks. The 365th day of the year would be a "Day Zero" after the end of the last month and before New Year's Day. (We could still add a leap day every four years to account for the earth's rotation.) A global transition to this system would have the minimum possible impact on our day-to-day life: the durations of the year, week, and day would remain unchanged; every month would be the same length as February currently is, and the number of weeks in a year would not change. If anything, this new calendar would simplify timekeeping on an annual scale, since holidays and yearly events would always fall on both the same calendar day and week-day, no matter what year it is.
Working in a chemistry lab, occasionally out of sheer boredom, I'd record and calculate things in microgallons, decipounds and centipints. I never could get around my boss Rudy's sense of time to escape the snap of his whip.

I worked in a clock making factory, owned by my father. One morning on my way to work, I was listening to the radio in my car, and the topic of metric time was the conversation. I must have come in to the show some time in the conversation. I heard, that we will have 20 hours per day, so many days per month and so on. I was on to this, and as soon as I arrived at work, with this new information ready to blurt out of my mouth in excitement. Dad was having a chat with the other workers, when all of a sudden, I expelled this new found information to the group. Dad, did you hear, that we are converting to metric time. We should jump on this straight away. We need to work out the gearing for the clock movements. Silence took over the room. A glare from my captive audience.

Some trivia on this topic that you might like: Clockwise is the direction that a shadow moves around a stick stuck upright in the ground in the northern hemisphere. The theoretical circle traced out by the shadow can be easily divided into 12 sections with a compass. But dividing a circle into 5 or ten is not nearly as easy. Cheers.
Also: at solar noon, the sun shines from exactly south - hence, in Hungarian, the word for south and the word for noon is the same ("dél"), while the word for north ("észak") is similar to the word for night ("éjszaka").
It is easier to split a circle into 8 parts rather than 12. The compass aid including, as there we have the north, east, south and west and four in-betweens. Or, if we like it so, we can split it even further into 16 parts.

Calling a 10 hour clock "metric" is stupid, because having it 10 hours means redefining how many minutes an hour has - or worse: redefining how long a second is. *For all intents and purposes, a 12/24 hour time **_is_** Metric time, because it's measuring time in seconds - an SI unit.*

One of the challenges of metric time is that it is inconvenient for shift work. You can divide 24 hours evenly into 2, 3, 4, 6, 8, or 12 parts, which works very well if you have 3 shifts (8 hours each) or 4 (6 hours each). Metric time can only be divided into 2 or 5 parts unless you use fractional hours.
The only real problem is division by 3 and 6. Dividing by 4 and 8 is not a problem. It's as hard as dividing 10kg into 4 parts - it's simply 2,5kg.
Well I would argue that in a perfect world we would count in base 12, but that would be hard to implement today

@@arthurclement8656 There is actually little gain of using base 12 over base 10.
In base 12 there is problem when dividing by 5 (and 10) that are also common dividers.
So you basically exchange one for another and there is no actual gain. You choose what you can write - 1/3 or 1/5.
Base 30 would be the closest one with actual gain - additional prime divider.
And that actually don't matter as in modern world for calculation we use computer swhich use base 2 - even worse (and probably the worst base system) as there is only 2 prime dividers and both 1/3 and 1/5 would result in infinite sequence of digits.

I was actually working in some software dev work at my university during the year 2000. I actually had to fix a bug in some code, because it had the every 4, except every 100, but not the except every 400. It wasn’t a big code change, and was pretty easy, but it did require me to read and understand all about leap year maths.
I must be a genius by comparison to most programmers during the Y2K problem, because my software planned for it starting around 1980 and I just laughed at all the fools who didn't think of it from the beginning!
A point of trivia: When the IBM PC came out, IBM designed the computer clock circuit to work the same as their mainframe computers, so they chose to start their PC clock on Jan 1, 1900. 1900 was not a leap year, making the circuitry in the chip more complicated. When Apple produced their first computers, they designed their clock circuitry to start on January 1, 1904. This meant that the circuitry was simpler and cheaper, because every 4 years from 1904 through 2096 are leap years. If your old Mac is still working during year 2100, it will not be able to display Feb 29, 2100 correctly (unless Apple fixes it via software).
And that is also why Microsoft Excel for the PC starts at date 1/1/1900 and Microsoft Excel for the Mac starts at date 1/1/1904.
@@jeffwells1255 Just a point, the Y2K problem was created by two things: 1) RAM and storage space was EXTREMELY expensive back when computers were first made, and programmers spent an extreme amount of time optimising programs to take up the least amount of RAM and space, and to run on the least amount of CPU cycles in order to to save money (back then, computer processing was MUCH MORE expensive than labor costs), and 2) most of these programs were not expected to still be in use in the year 2000.
@@ibnorml You forgot also to say that customers often complained about having 4 digits for the year, while they were used to use only two when handwriting...
Also, most displays were pure text displays (i.e. fixed number of characters on screen, often 80x25 or 80x50 characters). Same for printers, very often limited to 80 characters wide, sometimes 120 when using "condensed" fonts.
Therefore, "wasting" (irony inside...) 2 columns for an "useless" information was considered as a bad thing to do. But the digits, printed with graphical dots using TrueType fonts and followed by a currency symbol, located at the botton of the numerous Y2K bills changed this mentality A LOT.

Yeah, about that. A meter is the side of a cube of a mass of fresh water that weights the same as the average mass of a nautical ton which varies a little bit because any given localized 35 cubic feet of sea water may weigh slightly different amounts. The "ton" was already an international standard of displacement and to be accepted the metric ton had to literally be the same mass on a balance scale. Its kinda like how all shipping containers are actually based on the 24 or 48 foot size because of the international pallet standards and that the dominant accepting markets were still using feet. So the metric system is literally based off the foot.
@@prjndigo Um, no.
I always thought it was because 12 is so conveniently divisible, so you can split the time on a clock into a lot of different sized chunks for scheduling, without breaking into individual hours. And when you do have to break apart hours 60 (a multiple of 12) can also be neatly subdivisided based on need.
Base 12 makes a lot more sense than base 10, except that we have ten fingers. Otherwise, I bet we would have evolved to use it for everything, including the metric system (a gross meter vs centimeter)
@@PhilipKaskela
The issue though with base 12 is that it doesn't convert well into the standard Arabic numerals system that is used all over the world (because that's a base-10 setup).
Now the old Sumerian system of base-60 definitely had significant advantages for complex mathematics, but it seems that asking modern man to memorize a base-60 system is a bit much. For some reason.
12 is such a nice convenient number, being divisible by 3 and 4. We kinda sorta counted some things in a base-12 system, I mean we still use the word "a dozen", meaning of 12 of something. And in many languages (including English) we have unique words for 11 and 12.
@@1985ThePedro Babylonian cuneiform numbering didn't simply have 60 symbols. It was more like Hangul in that each digit was composed from smaller marks.
Here's what Wikipedia's Sexagesimal page has to say about it:
"The sexagesimal system as used in ancient Mesopotamia was not a pure base-60 system, in the sense that it did not use 60 distinct symbols for its digits. Instead, the cuneiform digits used ten as a sub-base in the fashion of a sign-value notation: a sexagesimal digit was composed of a group of narrow, wedge-shaped marks representing units up to nine and a group of wide, wedge-shaped marks representing up to five tens. The value of the digit was the sum of the values of its component parts:"
"Numbers larger than 59 were indicated by multiple symbol blocks of this form in place value notation."
@@ssokolow
That's a good point. It isn't that it was exactly a base-60 system when you were only considering numbers below 60, but more that if you had a larger value you would end up with less places than in the Arabic Numeral system commonly used today.
The Arabic Numeral system is also far superior to the Roman Numeral system for most number. Even though a number like 10 takes two digits for Arabic but only 1 symbol for Roman, most numbers in between become pretty labor intensive. And the math is also often labor intensive, even though it can be done by someone who is less mathematically literate.
The Babylonian system, with a value of 60 in each place, is even less labor intensive than the Arabic system, but does require a slightly more advanced literacy in mathematics to solve without excessive labor.
All that aside, variations of Roman Numerals (tally marks, which actually are precursors to Roman and not necessarily a variation) are probably the best method for keeping a running tally of a grouping. It's thought that RN evolved as a way of managing larger sets of these tally marks, and that the disposition of symbols to subtract from a value vs add to a value was a later feature.
Here (NL) there was this guy once who went to the local 'people bring art to experts' show with a clock he believed was weird but rather well made.

So the clock was very rare and woth about 150.000 euro.

One of the factors was because the clocks and watches were cutting edge high tech back then. You could force people to change the scales and rulers but time devices were much more expensive.

I saw an interview once with the guy at Microsoft who led the team that kept track of the world's time zone's, DST dates, stuff like that, to make sure instances of MS Outlook all around the world agreed upon identical times and dates for a given appointment.

This team had to browse like Chinese regional newspapers to find out that some province would switch time zone to match a neighbouring province, or discover that Chile is going to change the date at which DST becomes active.

A little trivia. As you mentioned, the meter was defined originally as "one ten-millionth of the distance from the North Pole to the Equator", which was actually measured from Dunkirk to Barcelona. The commission to measure that distance was signed by Louis XVI on the morning of the day the mob attacked Versailles and took Louis prisoner.
Also, it turned out that the measurements were wrong, which they tried to correct a few times. But by that time someone had put the scratches on the platinum bars. They didn't want to erase the scratches, so they ignored the measurements and just went by the scratches.
The group land surveyors left Paris to go out and start measuring, but they actually had great difficulty getting out of the city gates, since their pass had royal seals on it, and the guards were of the "new regime" (non royalist). If the head of the group who took the measurements would not have been persuasive enough, the group would not have been able to start measuring at all.

For example, you could feed your "mag" (robotic pet) every 2 beats, though players usually just said 3 minutes. It also eliminated the need for international groups of players to convert time zones.

Time is measured in the old Babylonian base 60 math system. They charted the rotation of the earth by observing the motion of stars and the general progression of the zodiac. This same system is used today in angular measurement. The metric system works because it was incorporated into an already existing largely base 10 math system. I say largely because Geometry uses some of the old Babylonian system. What I find pretty cool is that we are able to use the current base 10 and the old base 60 system together.

It's actually not too surprising. If you examine the symbols (and hence the math), used for the base 60 system it is actually a mash up of a base 6 system with a base 10 subsystem using different symbols for the two bases. To be more specific, they used one symbol to count to 5 and another to count to 9. There was no symbol for zero.

Thanks for the reference to VAX/VMS! It is pronounced like the first syllable in vaccine not as the individual letters. VMS is pronounced as the individual letters. VAX was the original Digital Equipment Corporation hardware platform that ran VMS but has since been ported to other platforms like x86-64. I'm one of the current VMS developers.
That base date that VMS come from November 17, 1858 is the base of the Modified Julian Day system.
The original Julian Day (JD) is used by astronomers and expressed in days since noon January 1, 4713 B.C. This measure of time was introduced by Joseph Scaliger in the 16th century. It is named in honor of his father, Julius Caesar Scaliger (note that this Julian Day is different from the Julian calendar named for the Roman Emperor Julius Caesar!)
Why 4713 BC? Scaliger traced three time cycles and found that they were all in the first year of their cycle in 4713 B.C. The three cycles are 15, 19, and 28 years long. By multiplying these three numbers (15 * 19 * 28 = 7980), he was able to represent any date from 4713 B.C. through 3267 A.D. The starting year was before any historical event known to him. In fact, the Jewish calendar marks the start of the world as 3761 B.C. Today his numbering scheme is still used by astronomers to avoid the difficulties of converting the months of different calendars in use during different eras.
So why 1858? The Julian Day 2,400,000 just happens to be November 17, 1858. The Modified Julian Day uses the following formula:
MJD = JD - 2,400,000.5
The .5 changed when the day starts. Astronomers had considered it more convenient to have their day start at noon so that nighttime observation times fall in the middle. But they changed to conform to the commercial day.
The Modified Julian Day was adopted by the Smithsonian Astrophysical Observatory (SAO) in 1957 for satellite tracking. SAO started tracking satellites with an 8K (non-virtual) 36-bit IBM 704 computer in 1957, when Sputnik was launched. The Julian day was 2,435,839 on January 1, 1957. This is 11,225,377 in octal notation, which was too big to fit into an 18-bit field (half of its standard 36-bit word). And, with only 8K of memory, no one wanted to waste the 14 bits left over by keeping the Julian Day in its own 36-bit word. However, they also needed to track hours and minutes, for which 18 bits gave enough accuracy. So, they decided to keep the number of days in the left 18 bits and the hours and minutes in the right 18 bits of a word.
Eighteen bits would allow the Modified Julian Day (the SAO day) to grow as large as 262,143 ((2 ** 18) - 1). From Nov. 17, 1858, this allowed for seven centuries. Using only 17 bits, the date could possibly grow only as large as 131,071, but this still covers 3 centuries, as well as leaving the possibility of representing negative time. The year 1858 preceded the oldest star catalog in use at SAO, which also avoided having to use negative time in any of the satellite tracking calculations.

When I was kid I tried to calculate metric time. This was mainly to aid in keeping time while out in space, long before I learned to the time space relationship with gravity. Anyway , my calculations were a mess trying to reconcile normal timekeeping with metric time. I only got as far as hours. Days, months, years could not be reconciled for normal relation.
- Seconds are Base 10
- Minutes are 6*Base10, 10*Base6, or Base60
- Hours are 6*Base10, 10*Base6, or Base60
- Days are 2*Base12 or Base24
- Weeks are Base 7 days. Weeks are dropped from reconciliation as unnecessary.
- Months have no Base varying from 28 or 29 days based on leap years mainly because a year ends in quarter day, and 30 or 31 day intervals. Months are then dropped from reconciliation.
- Years are Base365. With no months, Base(months) can not specified.
I was a kid (not even 10) and I'm sure I was close to hitting the nail on its head, but i think this was when math started eluding me for the more intuitive.

I tried decimal time for a watch, and honestly I absolutely love it! I can think of things in terms of percents. I can take really nice measurements of daylight and how long I sleep and when things happen! 1/2 = 50% 1/3 ≈ 33%, 1/4 = 25%, stuff i know well in decimal. Its been so nice! Im not sure how we ever lived with 24 hours a day 60 minutes... Etc. Especially when decimal seconds are a little faster, you get a finer measurement with them. ahh, im too lazy to switch back! Its just too nice.
kibble balance is actually what you achieve when you shake your cat's half full bowl to convince them there's still food in it
Below 70% denotes official emptiness, or if the bottom of the bowl is partially visible regardless of the residual column height.
Similarly the “favourite” food you have just purchased in bulk is immediately rendered inedible by proximity to more of the same and in direct proportion to convenience.
Brilliant 😺
@@ThreenaddiesRexMegistus So apparently I've recently read that this could be because your bowl is too small - if a cat's whiskers touch the bowl it can give them sensory overload which can be annoying / painful. So it's a lot better if the food is in the center of a very wide bowl.

@@igorfrancapereira4888 In Louisiana, there's still a number of people who speak French daily. And Spanish is the first (and sometimes the only) language for over 15 percent of the population in the USA, mostly in Texas in Southern California, which borders on Mexico. And I'm not even mentioning all the languages of the indigenous peoples in the USA, or all the languages brought there by immigrants who still use theirs within their communities, like Italian, Russian, Chinese, or even Yiddish. In fact, the USA has no official language (as in: codified by a national law.)
As a Spaniard living in a French-speaking country and married to a French guy, I confirm that trying Spanish accent makers the pronunciation more accurate than if he tried the English one. Also, this is an absolutely natural mechanism for people who speak more than one language: when you learn a third one, you apply to that one the accent of the second language (the one that you identify as "foreign"). I have French accent in German and Dutch, which is just ridiculous and confusing 😕
Most people never notice that Sept-Dec are named after 7-10 in Latin, since those were the seventh - tenth months until we added July and August to honor some kings.

@@Foxtrek_64 yes, my some "some kings" phrasing was highly sarcastic
It’s literally in the video that the change from julian to gregorian made the start of the year in January instead of March, which accounts for the mismatch in month names
Actually the Julian calendar used systematic names for months 5 and 6, before being renamed for emperors. The original Latin names were Quintilis and Sextilis, and if those names had survived, we could have Quintober and Sextember on our summer calendars! Even today's politicians monkey with time zones every few years. By the sun, each zone should be 15 degrees wide (360 / 24), with straight borders from pole to pole, but look at a time zone map of the world and you'll see the carnage.
11:28 it is also the same reason why there are 360 degrees in a circle rather than 100. Everyone was on the same page with that one.
Although there is a system for that called gradians. There are 400 gradians in a circle. They would have to use the gradians system to create time zones if metric time was introduced.
There is also the turn system. There are 100 centiturns in a circle.
1000 millieturns in a circle.

I didn’t watch this video until today and yet somehow I had an almost verbatim conversation about the preciousness of time in my head the other morning. So much a match that I had to watch it twice because I thought I imagined what you said.
I always thought that ... a system like that is something that we need.
- 100 seconds in 1 minute. 100 minutes in 1h, etc.
- 30 days in a month... seems ok. Although some of the other options you mentioned might work as well, but ... using our current month settings, just changing seconds, minutes, days and weeks, could work great.
- Now ... since many places are trying the 6h shift (instead of 8h), or the 4 day week. We could, "EASILY", have a 10 day week, with a 3 day weekend (Fri, Sat, Sun), with 3 new names for days, and ... maybe a middle-week day off, as Wednesday or Thursday (it will depend on the arrangement between the individual and the company).
- Such Idea, would give us a lot... A LOT!:
> Easier ways to measure time, allow us for faster calculations, AND, saving time in our lives.
> a 3-day weekend, helps with travelling. You could leave early on "Thursday" ... let's call it "Ragday" (for Ragnar, since, Thursday = is for Thor's Day), and ... catch a plane(or get into a car), and travel during Ragday (maybe even arriving on the same day), having Fri, Sat, and part of Sun to enjoy our trip, and the reminding of Sun to get back (and even rest).
> Having a 10 day week, would allow to split the year into 36.5 weeks, which would allow us (more or less), to predict what day for a specific date (bi-annually).
But at the end of the day ... I don't care about cultures, traditions, and superstitions. I would want a fixed system based on scientific thought. Let's have all the scientists, linguists, historians, etc. sit together and figure out a proper arrangement. Even if we move from the decimal to the duodecimal system, I'm onboard with it!.

I've worked 4 hour shifts, when you sail off-shore (ocean sailing, essentially). You do two a day of 4 hours each, 8 hours between each. It was law (maritime law). But (there is always a but): you could be worked OverTime during your off time. Of course it was "voluntary" O.T. Yeah, right. But, the Law also says a "watchstander" has to get 8 hours of uninterrupted sleep, every day, which can be split into 2, of which one sleep period has to give 6 hours of uninterrupted sleep, and the other 2 hours.
So, there were 3 watches: the Mids, midnight to 4 AM (zero to zero-4 hundred) and Noon to 4 PM (12=-hundred to 16-hundred). There is the 4-8, both Am & PM. There is the 8-12s, both AM & PM. That's for "watchstanders". There are day workers (that includes "night"), with any number of schedules, but still 8-hours workdays. Or 12-hour days. That is allowed to vary, even day to day.
Now, on Sunday, there is a rule left over from the sailing ship days called the "dog watches". You do some 2-hour watches so you change watches. That was so, on a long trip, you shared the misery or joy of each watch, didn't get into bad habits, etc. (Hey, the 4-8 watches have less supervision - which, with lousy or unpleasant supervisors, you get a break from them. But that was never an official reason: duh.)
Only sounds complicated. Some "modern" companies, and some military vessels, no longer "dog the watches".
It only sounds complicated. You get used to it.
Now:
In "protected waters", (The Inside Passage, certain rivers and lakes, the inter-coastal passage, etc.) you can stand 6-hour watches, 6 hours apart, for a 12-hour and no O.T. for that. So, you work an 84-our workweek, have a week off that's on shore. Or save them up for many weeks ashore. On my week-on-week-off trips, we were still considered "employed" on the weeks off, so still got benefits like Medical Insurance. Remember, we got 84-hours of work in one week, so that's two 42-hours worth of work.
There was a different system for "vacation" on the sea-going vessels.
Like I said, it only sounds complicated. (Yeah, right!)
Heave Ho, me hearties.
We cant change the second because the second has been scientificaly defined and is one of the base SI units.
@@Twiggy163 I didn't say "the second". I said minutes, hours... Still, the second is an arbitrary man-made creation, OF COURSE it can be changed! ;-)
@@TVfen "using our current month settings, just changing seconds, minutes, days and weeks, could work great."
I may have read it in a way different than you meant but, to me it says it right here.
The second is as arbitrary as the metre. Today a second is defined as ''being equal to the time duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the fundamental unperturbed ground-state of the caesium-133 atom''.
Changing it would ruin quite a few mathmetical equations... and my work.
Plz no...
I like the way you think, I wouldn’t mind to have 10 days weeks, 36.5 weeks year (One year with 36 weeks, and one year with 37 weeks). All this “time” notion is man made anyway… what would happen when we would have colonies on Mars (where the day length isn’t exactly the same). Days will drift, we would have to keep different calendar for each planets… and if Aliens come to earth, they would probably find this whole time completely stupid… and same with many other units anyway. That’s why it’s stupid to stick to units that don’t represent anything (like the Imperial system). And it’s better to define units using scientific measurements (like using Elements characteristics to define a man made unit).
To me, the biggest drawback of metric time is that you can't conveniently divide a day into fractional units other than 2 or 5. Imagine being the lord of a keep, or the skipper of a war frigate, and needing to set a watch rotation. You either have to have 5 shifts or 2 shifts, or else set partial hours, which defeats the purpose. 24 hours works much better, the more so even today with many more needs for shift work, when you can divide the day into 2, 3, 4, 6, 8, or 12 equal parts.
Honestly, this isn't really a problem once you use a complete metric system.
This is the same excuse as I often hear for measurements, it's easier to split something in 12 parts... With metric system you can easily convert to smaller units. For example instead of 0,6 = 6 dm; 0,6 dm = 6 cm; 0,6 cm = 6 mm; 0,6 mm = µm; 0,6 µm = 6 nm... 1 m divide by 40 is too difficult? convert it to mm: 1000 mm / 40 = 25 mm
A day could be 100.000 seconds or 100 kiloseconds (or if you change it to 1.000.000 seconds: one megasecond), and have the same duration as now if you adjust the duration of a second (but here's the biggest problem why we don't change it, all are technologies are simply based on our current seconds). And the prefixes aren't hard to learn: they are the same for everything.
It's just the way of thinking that needs to be changed. There is a reason why we work with seconds in more advanced maths, and not hours and days.
This is exactly why the Babylonians handled time the way they did. They used a base-60 counting system, which gave them a lot of really nice numbers to work with, including multiples of 12. So to them, 24 hours in a day was a round number, in the same way that a 25-cent coin is a convenient subdivision of the dollar.
@@denjo3131 That doesn't solve everything. For example, how do you write a third of a meter? 333 millimeters is too small, so is 333 333 micrometers, so is 333 333 333 nanometers, and so on and so forth. No matter how finely you subdivide the meter, the third-meter will never have a nice representation in metric units.
Which is why we should use base 12 or base 60 instead of base 10. But it would be literally impossible to switch our number base unless we started like a small space colony or something.
@@denjo3131 I'm not so sure its a clean as you say regarding shift work. If the day is 10 hours long and you have three shifts, then two of the shifts must be 3.3 hours long and the third must be 3.4. I mean, you can get more granular, with 3.333 and 3.334, and you can introduce smaller units (e.g. 3 hours and 33.33 minutes) but there is no way to make it even. You lose one unit of time to rounding error (e.g. 0.001 hours). To gain what?

Having grown up in England in the late 70s/80s, I grew up with a mixture of both metric and imperial measurements, and indeed to this day, I use both depending on what's more convenient.
If I'm reading a modern architect's drawing, measurements are almost always in metric, but the raw materials, such as timber, although now sold in strange metric numbers, are almost universally actually imperial.
For example, a plywood sheet might be sold as 2440 x 1220 x 13mm, but we all know it's 8 feet by 4 feet by half an inch (and actually, they tend to more accurately reflect imperial measurements in any case).
Metric measurements are easier to grasp, and I adore the interchangeability between measurements, but...

My notion of a new calendar: every week is 9 days long: you take the last 3 off, and trade off on who is on their weekend. there are 4 seasons, each 10 weeks long; each season is ended by a special extra day. And every 4th year is the usual leap year day. The key interest is not having a single common fixed weekend for everyone, so activity is spread out.

The most logical calendar would be 13 months of 28 days each, with one month containing four 7-day weeks. The 365th day of the year would be a "Day Zero" after the end of the last month and before New Year's Day. (We could still add a leap day every four years to account for the earth's rotation.) A global transition to this system would have the minimum possible impact on our day-to-day life: the durations of the year, week, and day would remain unchanged; every month would be the same length as February currently is, and the number of weeks in a year would not change. If anything, this new calendar would simplify timekeeping on an annual scale, since holidays and yearly events would always fall on both the same calendar day and week-day, no matter what year it is.
