Febuary every four years: "What I will ask you though is can you just give me one more day.. I'm not asking for a week, I'm not asking for a month, I'm not asking for a year. Can you give me one more day?"
The second is defined as a fraction of the 24 hours at a point in history . However the day itself is getting a tiny bit longer over long periods of time so a correction is sometimes needed ergo the leap second.
Actually, Britain didn't adopt the Gregorian Calendar until 1752, so DID have a leap year in 1700. Changing over also meant having to skip 10 days to get back in sync with where the dates should've been, but we had to skip 11 days because of having had a leap year in 1700 when we shouldn't have done
0:19 A day is not the amount of time it takes for the Earth to rotate once on its axis (that only takes 23 hours 56 minutes), but the time it takes to go from Solar Noon (sun at its zenith) to the next Solar noon, which takes four more minutes and therefore 24 hours.
there must be something wrong at 2:02, the timeline should be 1600, 1700, 1800, 1900, 2000, then 2100 and 2200, but the video shows 2010 and 2020 followed by the 2000.
As a lad (60's/70's) Mother taught me this rhyme ______" 30 days have Sept, April, June & Nov, all the rest have 31 except February alone, which has 28 days clear & 29 each leap year "
Re 13 month years of 28 days each (plus an extra 'year day' - read up on Cotsworth, folks), they might be easier for businesses but wouldn't it be boring to have your birthday on the same day of the week forever? Imagine if you were born on Monday.
..we must shift to more accurate StarDate..this totally eradicate the need for leap year and its offset adjustments...this Metric Stardates only needs to be adjusted to the daily shift of earth rotational drift in millis & micro...
Will the seasons eventually change with what the months currently have? Obviously many years from now, but still. Will the midsummer day change with it? This is very weird to me
i feel every leap year is a reminder that the year will be horrible look at it like this 2012: it was kinda terrible, world wise 2016: it was terrible, political wise 2020: it was sickness wise
because Romans believed even numbers to be unlucky, each month had an odd number of days, which alternated between 29 and 31. But, in order to reach 355 days, one month had to be an even number. February was chosen to be the unlucky month with 28 days.
I'm reviewing videos about Leap Day to show my elementary students, and I liked this one. Please know, however, that there's a minor mistake: the timeline, which counts by hundreds up to 2000, switches to counting by tens after 2000: ...1800, 1900, 2000, 2010, 2020. It should be 2100 and 2200. I'll see if my students can find the mistake!
when they say "we" they mean the Africans. What they did was messed up the math in the Calendar. The Egyptians had calculated that the solar year was actually closer to 3651/4 day. After 1,460 solar years, or four periods of 365 years, 1,461 Egyptian years had passed. The reason why Western societies use 4 years is because their society don't last for 1460 years. to have a proper leap year.. you need to have dynasties. dynasties requires LONG peace and stability. THE 4 year is wrong, the months are wrong as well. Julia Caesar wants a month , a month was put in. Queen Victoria wants a lake, a lake was renamed Ethiopia has the correct Christian calendar. The new year starts at the longest day of the year.
The first epistle unto the Thessalonians was written from Athens. "But of the times and the seasons, brethren, ye have no need that I write unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober. For they that sleep sleep in the night; and they that be drunken are drunken in the night. But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, Who died for us, that, whether we wake or sleep, we should live together with him. Wherefore comfort yourselves together, and edify one another, even as also ye do. And we beseech you, brethren, to know them which labour among you, and are over you in the Lord, and admonish you; And to esteem them very highly in love for their work's sake. And be at peace among yourselves. Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men. See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men. Rejoice evermore. Pray without ceasing. In every thing give thanks: for this is the will of God in Christ Jesus concerning you. Quench not the Spirit. Despise not prophesyings. Prove all things; hold fast that which is good. Abstain from all appearance of evil. And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. Faithful is he that calleth you, who also will do it. Brethren, pray for us. Greet all the brethren with an holy kiss. I charge you by the Lord that this epistle be read unto all the holy brethren. The grace of our Lord Jesus Christ be with you. Amen." - 1 Thessalonians 5:1-28
Every day is 24 hours, But in reality it takes 23 hours and 56 minutes for the Earth to orbit itself, 4 minutes every Day times 365 = 1460 minutes Which means 1460 minutes extra a year, one Day is 1440 minutes, so i dont see how it is only 365,24 days a year, Can anyone explain?
I had this same question today, so I looked it up, and the math didn’t add up. Therefore, I found this video and a comment said that we do not consider a day by Earth’s axis of rotation. Instead, apparently we use another cycle which in reality takes 24 hours
@@mathiashollbaum6312 A guy named wmarclocher on this video's comments said this: "0:19 A day is not the amount of time it takes for the Earth to rotate once on its axis (that only takes 23 hours 56 minutes), but the time it takes to go from Solar Noon (sun at its zenith) to the next Solar noon, which takes four more minutes and therefore 24 hours." That's how I reasoned through when responding to your comment. I'm not completely sure if he's right though.
@@mathiashollbaum6312 Yeah hahah I was also perplexed by that. Thank you for your comments because if you hadn't kept asking questions, I would have never understood something amazing! Ok, so this is the answer. Our days last exactly 24 hours because of the time it takes the Sun to be at the same point relative to the Earth as the previous instant. For clarity, picture both of these scenarios: the Earth rotating "on its axis" and the Earth orbiting around the sun. If you pay close attention, the Earth completes a 360-degree rotation in 23 hours and 56 minutes around its axis. On the other hand, when you take a close look at how the Earth is rotating around its axis, you notice that it is also orbiting around the sun. It is at this moment that you realize that because the Earth is orbiting around the sun, the Earth did not remain stationary, but instead followed an elliptical trajectory. Because of this trajectory, whenever the sun points exactly at the same point as the previous instant (before the rotation of the Earth on its axis), it finds itself 4 minutes ahead. You can watch this video to have a visual aid: ua-cam.com/video/WWw4JY2dNXM/v-deo.html&ab_channel=Interplanetary To fully understand, notice how the Earth goes upwards (following an elliptical trajectory on a small scale) in the video. This creates the offset that confused us so much! Also, after watching the video, notice that this has nothing to do with leap years because the Earth's time duration of orbit around the sun has nothing to do with the way we count our days. Instead, we (astronomers) used our 24-hours-lasting-days to measure how long the Earth takes to orbit the sun (which turns out to be 365.24219 days that last exactly 24 hours). Because of this extra .24219 ≈ .25, we use leap years as it is explained in the BBC News video. Hope it helps! If you have any other questions (about any science-related topic), feel free to ask me! Have a great day!
Technically, Pope Gregory XIII did not actually create the century exceptions. All he did was assign two astronomers, Christopher Clavius and Lilius a job to find a way to reform the calendar. Once they found out what to do, they asked the pope if it was good and he ordered it to be in effect. So yes, it’s named after the pope, but he didn’t actually make the rules, so to speak.
The gravitational drag caused by our moon is gradually slowing down the earths rotation, causing every day to be slightly (as in millionths of a second slightly) longer than the last. So if you ever thought to yourself "Today feels like the longest day of my life", technically you're right.
Exceptionally poor explanation. The additional day and rotation of February 29th represents 1461 days/rotations covering four complete circuits of the Sun. It is derived from a specific astronomical event - the first annual appearance of Sirius as a dawn appearance - ".. on account of the procession of the rising of Sirius by one day in the course of 4 years,.. therefore it shall be, that the year of 360 days and the 5 days added to their end, so one day shall be from this day after every 4 years added to the 5 epagomenae before the new year" Canopus Decree 238 BC The wrong point of departure is trying to explain the leap day as 365 1/4 days, the correct point of departure is demonstrating what causes Sirius to skip a first annual appearance by one day after the fourth 365 day cycle.
If leap years were omitted we could have Christmas during Northern Hemisphere astronomical autumn after 20 years or so Latest Solstice Date is December 23 so we would need to drop another leap year or two for it to work

If you go to bed when the sun goes down and get up in the morning.who cares about whether the year leaps or not.i don't use leap years.i just care about a job .leap years were Invented by people with too much time on Thier hands.
A bigger question i have is why February only has just 28 days? I get that other months have 31 but more months can have closer to 30 to avoid February being so short...
because Romans believed even numbers to be unlucky, each month had an odd number of days, which alternated between 29 and 31. But, in order to reach 355 days, one month had to be an even number. February was chosen to be the unlucky month with 28 days.
