- In this video Neil deGrasse Tyson tells us the story of the current calendar known as the Gregorian calendar, where it was containing additional 10 days. watch the full video for short for the details.
Neil deGrasse Tyson is an American astrophysicist, author, and science communicator. Tyson studied at Harvard University, the University of Texas at Austin, and Columbia University. From 1991 to 1994, he was a postdoctoral research associate at Princeton University. In 1994, he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. In 1996, he became director of the planetarium and oversaw its $210 million reconstruction project, which was completed in 2000. Since 1996, he has been the director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. The center is part of the American Museum of Natural History, where Tyson founded the Department of Astrophysics in 1997 and has been a research associate in the department since 2003 ... ( From Wikipedia)
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun ... Wikipedia
The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Berbers.
This calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the earlier Roman calendar, a largely lunisolar one. It took effect on 1 January 45 BC, by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria ...Wikipedia
A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) added to keep the calendar year synchronized with the astronomical year or seasonal year. Because astronomical events and seasons do not repeat in a whole number of days, calendars that have a constant number of days in each year will unavoidably drift over time with respect to the event that the year is supposed to track, such as seasons. By inserting ("intercalating") an additional day (a "leap day") or month into some years, the drift between a civilization's dating system and the physical properties of the Solar System can be corrected. A year that is not a leap year is a common year ... Wikipedia

The fact that it took 1600 years for the Julian calendar to slide 10 days is really impressive.
If you like that fun fact. Look up what the longest year. The Romans had to keep updating their calendar due to its inaccuracy and this was Julious Ceasers job as the pontius maximus (head priest) hence why he then invented the Julian calander to fix it.
@MDL24 I have watched the history civilus series on Roman history. It is where I learned about the function of the Julian Calander.
@@SerunaXI Same, its a good series.
@@MrZenmancer That isn't correct at all there was only an 11 day difference. Even when the Soviet Union adopted the calendar in 1918 they only had to drop 13 days. To work out the difference as you can look up what they changed. Basically there are no leap years every 100 years on the Georgian calendar but there still every 400 years so every 400 years you need to lose 3 days to correct it from Julian to Georgian. For some reason it was only 11 days off not 13 as you'd expect from this system but I guess the Continent when they adopted the Georgian Calendar didn't update 2 of the days themselves for some reason.
Jus tell me this how can Nan who didn't make the days seasons months or years get 2 put take add or subtract days from calendars??? Whoch ate not just calendar editing we tlkn bout real life days of life ctfu like do yall even pay attention 2 anything other what they advise yall 2 look at???
I remember in high school making a paper out from the history of the calendar. I thought it was going to be easy essay 1,2,3. Nope it blew my mind and I ended up studying three types of calendar from past to present. Hard to understand.
Whenever I'm late for work this music plays
I’m crying 😂
Bro became a robot halfway through
Oh yeah someone added a stupid filter or whatever to his voice.
@goku9000 you have only 60 seconds I'm youtube shorts. They have to speed it to cramp it
Mayan Calendar: Am I a joke to you?
kinda
Neil left out the "tweak" that was added to the Gregorian calendar to fix the bug.
Leap years are only implemented in century years that are divisible by 400. 1700, 1800, and 1900 were not leap years, but 2000 was because it is divisible by 400.
What happened to the Dark Ages? Turns out monks didn't "just kill" all the smart guys, they there THE SMART guys!
Well in Ethiopia we hae a completely different calendar, still have a leap day !
I’ve heard about that
The Bharatiya lunar solar panchanga system had figured this out long before
the west dont like to hear this
Cope harder 😂
Nope
People flipped the F out about those 10 days being taken away. They thought that the powers that be were literally taking 10 days off their lives.
Sounds like wild times.
That's because people lived to like their late 30s.
@@stoundingresults Woosh
In Nepal our calendar is totally different we follow solar time not the lunar and here's 2079B.S
Now I want a Gregorian Calendar to hang on my wall.
If you have a calendar, then you do have one. We use the gregorian calendar.
Again , thanks 👍 Neil for another great lesson love you bro!
If Slartibartfast had been on top of his game, this "How long is a year?" problem would be a lot simpler to solve.
Kids from the 80s might remember the Halloween Pumpkin trash bags that you filled with leaves. Now the leaves don't fall until November.
Mayans in their graves be like;
"Bruh are we a joke to you?"🤣
Exactly. I was gonna say the mayans developed a calender so accurate they only need a leap year every 400 years or so.
Yes they actually are
Just call them The Maya.
The persian calendar is the most accurate, it only needs a correction every 141.000 years. And its older than gregorian
Yes they are a joke
Thank you 🙏 Dr
@@nooneofconsequence1057 I’m a science guy my self, what makes you think he got it wrong?
Is the calender longer than it was before?
I understand....can't explain but I've seen this to a beat my entire life.
Actually, it was October 1582, not 1584. But this is interesting!
I still don't get it. Is the year getting longer??
Sad thing.... workers owed rent 10 days earlier that month, yet earned 10 days less pay for the month....
360 days + 5 days + a leap year was used in ancient Kemet. So... how is our calendar more accurate, when it is the same as our ancient knowledge?
quiero que me salgan mas shorts asi :)
what about ortgodox coptic calendar ?
My $19 dollars Casio gives me the perfect calendar and is built in Tokyo, Japan!
What is the name of the song
Nobody in the comments section pointed out the fact that he was wrong. It’s actually 1582 not 1584.
But some countries kept the Julian calendar for several centuries more. Thus they had to take more days out of the calendar. Possibly this calendar shift brought popularity to the preexisting song, The 12 days of Christmas. Which was the period from Christmas to the feast of Epiphany. Incidentally the items in the song changed over the years previously including a pig and a bear.
Your timeline is confused. The Gregorian calendar came long after the 12 days of Christmas, not before.
@@allendracabal0819 You may be correct. I was repeating an unconfirmed story someone told me but a little research shows me that it was the period between Christmas and the feast of Epiphany. So thanks for pointing out my error, you learn something new every day.
Yup, that's why George Washington has two birthdays because England changed calendars when he was 21 years old.
Yes caladers great....but the background song? Name?
Actually 1582, not 1584, for Catholic Europe and not until 1725 for the British Empire!
So we base our calendar on the seasons, not on the movement around the sun?
Seasons are different from a year?
And here I thought that the reason is that the Earth's rotation is not perfectly synced with its orbit. So if an orbit starts at midnight it will not end at midnight in exactly 365 days but about 6 hours later, and so we need to account for that extra 6 hours by adding a day every 4 years (with some exceptions).
On March 10th I was born😎
That, don't mean they had to take away a whole month. Vader was the month.
If we never created time would time still exist? What actually is time ? And why did we create it and how ?
The heavens are COMPLICATED. There are several things we could base our year on, but as Neil indicated, we base it on the Tropical Year, or the length of year that keeps the seasons from drifting through the calendar due to the Earth's precession of its axis of rotation.
But the price we pay for that is that we abandon the sidereal year, and our constellations instead drift through the calendar. In about 12,000 years, Orion will be our companion not in the winter skies, but in the summer skies.
I, for one, can't wait.
Dr Meghnad Saha has detailed official report on how this Gregorian calendar has its major limitations. Ancient Indian Calendars are far more complex and more precise, instead.
Far more precise with respect to what? The seasons? The stars? The sun? The moon? Opposition with Jupiter?
You have to pick one, and since they are not integral multiples of one another, picking one means abandoning precision with respect to all the others.
@@Astronomator integral multiple is a limit you are highlighting, which essentially is rooted in the order of magnitude one is calculating those events & the reference from where one is seeing the event. Using light-years, I cannot say that Sydney and New York are 0.00...some..001 light years away from each other so this is ignorable so essentially they are near to eachother. So this is where the difference is, that Indian Calendar System acknowledges and uses them to make well in advance formulated adjustments in the calendar based on studied-in-detail celestial motions.
We must acknowledge that despite the centuries of suppression on Indian soil, the formulae and calculations on Indian texts have still survived (atleast 5 out of earlier known 15 or so). So what we know now is only out of those remaining works. They were definitely being used to plan key big events during British-rule and before, the famous Kumbh festival for example has a long continuous history. And cut-off from most (not all) of the ancient logics of why/how the formula for these rules came-up, the Indian calendar is now increasingly getting importance amongst Indian diaspora atleast, with the more modern science findings turning out to be in alignment with what the ancient calendars had formulated - a small example is about the variation of unit of time, with speed.
Post independence in 1947, India wanted to develop its own calendar system, a standardized system nationwide. The resulting official report by a respected scientist lists in detail, the depths to which ancient Indian calendar system went compared to the others; however for remaining in touch with the rest of the world, the new system suggested in using the months as suggested in the Gregorian Calendar & also the year numbering, but adds that the adjustments suggested in the ancient Indian calendar are far more detailed and with more scientific logic.
@@tol-mol-ke-bol Though the difference in timing between two periodic celestial events might be small, even small differences will propagate into huge discrepancies over long periods of time. At some point, a calendar based on two or more such periodic celestial clocks must fail.
@@Astronomator true. There are limits to every thing, and microsecond discrepancy now can create significant difference atleast over vastly large scale. But does that become a reason to ignore that system of calendar altogether? Instead, if a system can accommodate more cycles and events with much finer understanding of progression of time, and cycles, and significance of referential points; compared to the other which has only five aspects: day, week, month, year, and adjustment of leap year; then let us be honest about which calendar-system had better intent and approach to be closer to precision than any other
And it's still off and we lose days in the season. 2023 and it's blatantly evident.
And here I thought the seasons started on the first of March, June, September and December.
Why?
@@ScottysHaze Cos that was what I was told.
That's crazy how we so small on this planet and we tracking how the earth moves around the sun in space. I feel like we aren't that safe anything can happen at any moment and we're fucked.
There was outrage about people 'losing' 11 days, and I read a great book about it once (but can't remember the name lmao)
If it was that accurate then the 1st month would be Unusary, 2nd - Duoary, 3rd - Tresary, 4th - Quattuory, 5th - Quinque (😯), 6th - Sexuly (yes please), 7th -September, 8th - October, 9th - November, 10th - December, 11th - Unidecimber & 12th - Duodecimber
You all know we have a noticeable 2 to 300 years of record history that's just no where to be found
i thought the mayan calendar is the most accurate of all calendars
No, the Mayan calendar is just famous because of how close it is to being accurate even though it was made by very primitive people.
The present Hebrew calendar was put into effect by Hillel II in the year 358 CE. [T]he Hebrew calendar must be in harmony with both the lunar and solar cycles. The accuracy of this calendar ... amounts to [a discrepancy of] only one day in 14,000 years. More remarkable yet is that this error was less in the past, since there has been a decrease (very small) in the orbital period of the moon. [quoted from Computers & Mathematics with Applications, Vol. 39 (11), June 2000, pp. 23-24.]
🤔 Neil deGrasse Tyson's brain is a Dodge Demon engine on nitrous! 🤣
Not quite the whole world; the Orthodox church calendar still follows the Julian calendar.
Wait till you all have seen the Indian calender...perfect in all ways...year divided into months days and stars aligning for that day..perfect in every way
Interesting. What is it called and what specifically about it makes it superior to the Gregorian Calender?
@@jonkornealus9604 It’s so accurate to the dot from sunrise,sunset,constellation,season,lunar positions,eclipses of sun & moon, and many more. But the most interesting thing it’s already written long back. Could you tell when is the next solar eclipse from gregorian calendar? You can’t find then search in Panchangam you know the year,date,time dot to the seconds!!!!!
@@jonkornealus9604nothing
It's so perfect that no one has heard of it, and no one uses it. Ok, Gotcha!
@@MrT------5743 see that fire over there?
there should be 13 months in a year at 28 days each
The Maya had several calendars that were more accurate than ours
More accurate with respect to what?
A year can be based on many things. An integral number of days, an integral number of lunar orbits, a full orbit with respect to the sun, or a sidereal year with respect to the stars to name a few.
The trouble is, these things are not integral multiples of one another. So picking one necessarily means abandoning accuracy with respect to the others.
We, for whatever reason, have decided to adopt the Tropical Year, which is accurate relative to the precession of Earth's axis of rotation. On that basis, (albeit on that basis alone) our Tropical Year is absolutely the most accurate.
This is not true.
@@Astronomator ...Can you elaborate on the sidereal year with respect to the stars ? ...And what's the amount of difference in _TIME_ between the different methods ?
@@nikolaikalashnikov4253 The tropical year is measured from vernal equinox to vernal equinox. The sidereal year is the length of time it takes for the sun to return to the same place against the background of the stars.
Tropical Year: 365 days, 5 hours, 48 minutes, and 46 seconds
Sidereal Year: 365 days 6 hours 9 minutes 10 seconds
In the Tropical Year, the constellations will drift through the calendar.
In the Sidereal Year, the seasons will drift through the calendar.
Alas, accuracy with respect to one means inaccuracy with respect to the other, so you just have to pick one. For whatever reason, we've chosen to adopt the Tropical Year.
What about the 13 month calendar? Hmmm?
I like that idea. The months could be numbered like cards in a deck (Ace through King), and the four weeks (no more, no less) in each month could be the card suits (Spade, Diamond, Heart, Club).
We would need an extra day (two extra days in leap years) to fill out the year, so I propose that those days would be entities unto themselves, not in any of the months. Those days would of course be known as...
Wait for it...
The Jokers.
He has an ego the size of Jupiter
If you're interested in complaining about egos of people in the public eye, there are many far more suitable subjects out there to choose from than a guy who is trying to educate and share knowledge.
@@allendracabal0819 No I’m not interested in searching the internet for large egos; I have better things to do with my time. But when I see an obnoxiously large one in front of me, I am likely to say something.
my calendar is much better. it goes like this…. friday, saturday, sunday, friday, saturday, saturday, sunday.
Mayan Calendar is far more accurate than the Gregorian or Julian Calendars. It never needs a leap year or to subtract any number of days. It keeps running indefinitely. However, #neildegrassetyson seems to not care about the accuracy of his words on other topics, so this shouldn't be a big surprise.
the mayan calendar doesn't track seasons which is kind of an important pratical feature for most cultures on earth. given agriculture and countless other things. it works for Guatemala/southern mexico because the seasons there happen to be subtle closer to the equator
All solstice will happen anyway, just assign the day it will happen.
Nop!! The Persian calendar is based on all equinox’s & starts from spring equinox which is the first day of the year so it’s always super accurate.
No it is not, did you even watch the video? the seasons compared to the earth's orbit of the Sun is not accurate when trying to use the persian calendar. We base time on solar positioning, not what season it is; that's why the Gregorian calendar is superior in every way. If the Persian calendar was more accurate, we wouldn't be basing some of the most complex science imagineable on a less accurate calendar system. Any space expeditions would be disastrous if we used the persian calendar, since we'd have a much harder time pinpointing a trajectory to other planets if we did. That's just a few of many examples why the persian calendar is outdated and therefore not used.
-sorry for the long comment, I'm not replying so I didn't want to miss anything
Calendars are merely human constructs that gauge the passing of time in a way that is convenient for us. Existence doesn't give a crap if we get it right or not.
True af
Well yeah no shit but it is crucial for our own society
Well that's finer than frog's hair split eight ways especially the bug-eyed black frog
"Ever devised" is flat out false. It's the most accurate calendar ever implemented.
7 days in a week, 52 weeks in a year
7x52=364. Where did they get the extra day from?
They wanted to make it a nice number cause us humans our ego is in our way
13months 28days 364 a year
It’s not exactly 52 weeks. Its 52.143 so multiply that by 7 = 365.001 days
Oh 😂😂 most stupid calendar
You don’t know what you’re talking about!
I think the calendar is off by about 15 mins a year. Anyone else think the seasons change in temperature about 2 to 3 weeks later from Whichever equinox? I asked my grand parents about this and they (all 4) said that the seasons temperature change used to be off by about 2 weeks, now it's noticably 3 to 4. Just a thought. Could.blame global warming I guess. Personally, I 100% blame Neil DeGrass Tyson. It was him, always was...
We Hindus in india have completely different time systems and it’s completely based on seasons
I like how "Oct" is 10th month of the year even though "Oct" means 8. Same thing with "Dec". It means 10, so why is it the 12th month of the year?
And sept means 7
So why don't we have 13 months in a year ? That way every month was 28 days the first would always be Monday and the 28th would always be Sunday. Every month would be exactly 4 weeks instead of 4.257. I know it's only 364 days a year so we would have to add a random day to each year but I don't see why this is any less confusing then our calander today with leap years and daylight savings time . My guess is that over centuries ( with the rotation of the planet around the sun ) our calander wouldn't line up anymore
How did the years i533 and i587 jump to i622 & 1587, and, J700, J800, jump to 1700, 1800? Whats really going on here?
But that's an 11 day difference
🌐🌏🌎🌍🌐
Julius Caesar got the current calendar from Cleopatra during his African campaign. Their incorrect calendar year started with March….October was their 8th mo. The original African calendar was a part of the “inheritance”……12 mo x 30 days ea. plus the five festival days. There was also ancient texts abt the “adjusting of dates”.
I think it would be more practical in our modern life to have a 13-month calendar that would give every month 28 days and every date would be on the same day that would make for 364 days new year holiday would make it 365 days that would be outside of the calendar and two new year day holidays on leap year and you start the year on January 1st as always back from the holidays.
Listen to that an atheist saying that a Christian did something good.
and look now, Easter is off by 2 weeks in last 25-30 years.
Do we know how to count time?
You have a Chinese calendar. A Persian calendar where nw year is the 1st day of spring. And look how the islamic calendar work. The time. So who are we to say which one is better...
They’re all good except for the western one 💀
This system works better for almost everything lol so everything says it's better
Matt Parkers calendar is the most accurate ever devised:D
The Gregorian calendar is accurate to within one day in about 3,236 years, while the Persian calendar is accurate to within one day in about 110,000 years.
Reading up on the Persian calendar, they don't even have a set number of days in a year. It depends on when the actual vernal equinox occurs. So let's say 100 years from now, the Persian calendar don't even know how many days it will have.
Nothing is predetermined with their calendar. How does that make it more accurate when they just willy nilly add days to the year. Whenever it gets off with the equinox?
@Larry Thielen Sounds wigglingly wobbly and timey wimey to me.
@@charlesray9674 sounds very inaccurate to me.
@@MrT------5743 instead of basic every-four-years pattern of leap year, the Persian calendar has a more meticulous pattern for leap years. This pattern is not random. Educate yourself.
@Hessam Alizadeh I actually did educate myself. Maybe you should too.
Persian calendar changes depending on observations of the equinoxes, not by mathematics. You can't even do a conversion and calculate days more than a few decades in advance cause you and they don't know when an extra day will get added to the calendar.
From google:
The Persian calendar has a leap year every four years for a few cycles, then a five year leap interval (usually 29 or 33 year cycles) as necessary to place the first day of the year on the equinox using Iranian time.
the most accurate calendar was created by hakim omar khayyam ,Persian scholar, 1000 years ago.
The Jewish calendar (lunar)had it figured out. But they use a lunar month every so often.
Crazy
The balken states and Russia still use the Julian calendar hence why there Xmas is in January.
Wrong, the Vikrami calendar is the most accurate one
.... Joe just asked him if this year is a leap year.
Ahahahaha
While america was just discovered.....
Everyone has got their own opinion based on limited knowledge they have.
Like you?
What a meaningless sentence
I read somewhere that the MAYAN calendar of 13 months(28days each)+1day, +1solar day every 4 years is the most accurate real calendar??????
I found some say other calendars were better
or perhaps u can use the 13 month calender like we originally had and not need leap days
It's 13, not 10 days.
What happened to daylight savings time
Bullshit, the best and the most accurate calendar Persian Calendar. Which the first day of the year starts with the first day of spring 🌼🌱.
I swear this guy over explains the simplest shit to sound like he knows what he’s talking about
North korea does not use this calendar ......
Try explaining that to a Republican
clip channels can’t even just upload a clip from anything raw they gotta add a shit soundtrack and speed up the audio
Come to India you will learn a lot about the calendar from Hinduism
Most “accurate” taking from the original and removing days. Right smh
A person took this information and created a snippet of it and collagulated it with a sound snippet that it had no relation with and produced this concoction that has no relation other than create clout from it.
A year is 365.25 days
WRONG. it's actually 365.24 days. this is why you skip a leap year every 1000 years or whatever.
