My question has always been: Why have 4 months with 31 days only to have a 28/29 day february? Why not take a day off two of those 31 day months and give them to february. Thus 2 months always have 31 days. 9 months always have 30 days, and february changes between the two. Instead of two completely different values.
While it would make sense to do something like this and many new calendar systems that rearrange months and weeks have been proposed, including some that would make a week either 5 or 10 days, everything is pretty much situated on the calendar we have now and everyone has pretty much decided that the amount of confusion involved in changing things like birthdates, anniversaries, and holidays (especially religious ones like weekly sabbaths) would be more difficult than simply having a weirdly numbered month in the late winter.
Because the Romans were annoying. January and February were originally the last two months of the year (which is why February is the short month, and also why SEPTember, OCTober, NOVember, and DECember have names meaning 7, 8, 9, and 10 despite currently being the 9th, 10th, 11th, and 12th months). February also used to have 29 days (30 on leap years). However, when the month of Sextilus (which had 30 days) was renamed Augustus in honor of Caesar, it was decided that it couldn't have fewer days than the month named after Julius (which had 31) days, so they stole a day from Februarius and put it onto Augustus. This is also why you have two months in a row with 31 days.
I wish we could go back to when we had 10 months, after all, December comes from decem, latin for ten, with added bet at the end, so does September, septem means seven and you can guess what the months between them mean The reason why they don't align is because julius and augustus wanted their own months
It's not ''Pudge'', Pudge only borrowed the skin model of the Abomination from the actual Warcraft 3, just like every other hero in DotA, since it's a mod for WC3 :)
I guess depending on which way around the error is, years divisible by 8000 should either be double leap years (with 30 days in February?) or not leap years at all? But either way, people will cross that bridge in about 6000 years

What's beautiful about this is that when the pattern repeats after 400 years, there has been 365*400+97 days, which is divisible by 7, so even the the weekdays will be the same as they were 400 years prior.
You’re on the right track. But in 2020, February 29 was on a Saturday, so will the years 2048 and 2076. I wouldn’t say it repeats every 400 years. It’s every 28 years unless you cross over a century not divisible by 400. In my prior example, the years 2048, 2076, 2116, 2144, 2172, and 2212 will be the same calendar.

Brandon Fisher Leap years coincide with campaign years giving us an additional day to be miserable, except in 2000 when we were miserable for four years.
Leap second could be sly solution for ironing out imperfections of calendar+random disturbances -- provided that its ɛ remains bellow say 1/4 of a second per year (or as low as possible). Milankovich (Milanković) presented his "reformed Julian calendar" in 1923 and it has such features. It's shame that no one mentions it in their thematic videos (neither M. Parker nor Vsauce).
CGP Grey, you make my brain hurt, but your videos are always amazing, educational, and funny! Thank you for doing your research and making important videos entertaining. You're awesome!!!

I love your videos, there absolutely great. I was wondering tho, if you could make a video explaining this whole Kony 2012 thing. I'm sure it would be quite helpful!
When we get the technology we should displace mass to make the length of the year precisely 364 days. 364 is divisible by 7, and 28, so division of dates won't be an issue. And since I said precisely, if we maintain this the seasons will never drift.
xkcd's What If series covered this question pretty thoroughly here: what-if.xkcd.com/26/ Suffice it to say, speeding up the rotation of the Earth by even a single millisecond would take hundreds of massive asteroids and probably wipe out humanity. Speeding up the Earth by an entire day would probably destroy the entire crust unless we take a couple million years to finish. Either way, the extinction of humanity probably isn't worth it.
Because for the Romans it was an important month (purification) and when Caesar decided to change the calendar from a lunar one(28 days per month) to a solar one(30 days per month but adding 1 day more to some months) he decided to let february with 28 and use it as the month where a day would be added in leap years(they already added days to keep in sync with the seasons, the problem was that it wasnt something automatic but the job of the Pontifex Maximus (Caesar all that time) but if for some years he wasnt able to do so (like in the Roman civil war) then all the calendar went downhill very quickly
For my D&D game we use a lunisolar calendar that always starts the month over on the first day of the full moon, and the year starts over on the first full moon following the winter solstice.
Alright before i watch the video, ima say what others have told me, even though it is very likely *wrong*. *a leap year adds and extra day because every year is not 365 days, but 365.25 days. so that means that every four years it would add up to 367 days.*
Sorry to correct, but to be even more precise, it's 365,24, and then even more numbers. This comment is not supposed to be offensive or rude, but to help others.

I've always been a fan of the 28-day month, 13-month per year calendar, with a 5 (or 6 for leap year) day new-year's holiday. This calendar also moves the beginning of the year back where it should be, the Vernal Equinox.
2:57 Well, no. The calendar drift has nothing to do with our measurement techniques. It's not a technological problem that you can science your way out of. As long as humans are living on earth, we will have to deal with it. And so leap years will continue to exist.
Why can't we have one calendar for every year? Hear me out! Just have the last day of the year last longer and even if you use the leap year system have the extra day at the end of the year instead of February. Then make January 1st start on a Thursday every year regardless of what day of the week the year ended. Why Thursday, so we can have a long new years holiday and back to work come Monday.
A day is 24 hours long because that's the time it takes to make one rotation. If the last day is made 30 hours long, it might help keep the seasons in sync, but your day/night cycle will keep getting shifted by 6 hours each year before it syncs again after 4 years.... hope I am making sense... :)
jackrussel13 Take away making the last day longer part. Just put the leap days at the end of the year and start the year on the same weekday is still a good idea.
For the Romans, the founders of our chalendar, the year originally ended with February (count it, September was originally the seventh month (septem = seven), October the eigth (octo = eight), November the ninth (novem = nine), and December the tenth (decim = ten)). So the leap day actually was added at the end of the year. The calendar was shifted because of the roman law, that said that gouvernors of all areas of the Roman empire (back then not yet an empire) had to come to Rome to account for their actions (and also elections, I think). The chalendar was shifted to make it easier for the gouvernors to travel. The Mare Internum isn't a place you want to be in the middle of around end February-begin March, it's stormy and dangerous. December on the other hand, gives you a relatively calm sea to sail on. This change in chalendar was just Roman problem-solving.
There is a proposal that's been floating around for awhile that is similar to this. It is called the World Calendar. It is set up so that each quarter year, the first month has 31 days, and the other two 30 days. In the middle of the year, between June and July, there would be a day with no numerical date or month, which isn't part of any week, called "World's Day". On years where we need a leap day, you add another similar "World's Day" to the end of the year. The benefit of this calendar is that every particular date always falls on the same day of the week, every month always starts on a particular day of the week etc. Of course, a lot of people don't like the idea of having days that aren't part of a week, it can screw up a lot of things, so the idea hasn't really caught on.
haha I never knew about that crazy rules. I knew why there is a leap year but I really though they just left it at that :) God damn calendar designers, I have much more respect for them now.

Leap years coincide with campaign years giving us an additional day to be miserable, except in 2000 when we were miserable for four years.
@Sean Hiseman The Leap Years are always doomed. 😉
euewheuef it 2020 now
@@doyoungod8212 True, 2020 now makes 2016 4 years ago and 2012 8 years ago.
CGP Grey, why are you the best at explaining things I never knew I was interested in? You're awesome :)
My birthday being on leap day is so confusing
Leap second could be sly solution for ironing out imperfections of calendar+random disturbances -- provided that its ɛ remains bellow say 1/4 of a second per year (or as low as possible). Milankovich (Milanković) presented his "reformed Julian calendar" in 1923 and it has such features. It's shame that no one mentions it in their thematic videos (neither M. Parker nor Vsauce).
CGP Grey, you make my brain hurt, but your videos are always amazing, educational, and funny! Thank you for doing your research and making important videos entertaining. You're awesome!!!
Here In 2020 (Leap Year)
lol, who saw the [warcraft]** abomination in the bottom left corner? at 3:06
WE DONE WAITING
Warcraft 3. ^^
you must construct additional pylons
...... starcraft?
Whoops, meant warcraft. I've put hundreds of hours into both games, but I just recently got the new starcraft, so that was on my mind at the time lol. I had been living on Brood Wars for SC until now. :P
100 Days of Code challenge. Life if that's the reason you're here.
Saturday February 29th, 2020, good Leap Day to everyone.
amazing!!!
yeah!
"Christmas in the summer?? The hell??"
Southern Hemisphere people: -_-
The fact that this was uploaded on Feb. 28th and not Feb 29th, although the upload year was leap year.
Who’s here because it’s the 29th of February 2020😁
I love your videos, there absolutely great. I was wondering tho, if you could make a video explaining this whole Kony 2012 thing. I'm sure it would be quite helpful!
We have christmas in summer....
lol
Stupid is stupid. And now I am done with you. Blocking in action.
although would be fun if you could switch every few hundred years...
When we get the technology we should displace mass to make the length of the year precisely 364 days. 364 is divisible by 7, and 28, so division of dates won't be an issue. And since I said precisely, if we maintain this the seasons will never drift.
And what are we gonna do with drifting days?
Redefine hour or get some funny looking watches?
Commie Jesus Redefine the hour.
Let's hope no one smart enough to come up with the technology is stupid enough to try and use it.
Blood Angel What's wrong with this? I think it's a good idea to do.
xkcd's What If series covered this question pretty thoroughly here: what-if.xkcd.com/26/
Suffice it to say, speeding up the rotation of the Earth by even a single millisecond would take hundreds of massive asteroids and probably wipe out humanity. Speeding up the Earth by an entire day would probably destroy the entire crust unless we take a couple million years to finish. Either way, the extinction of humanity probably isn't worth it.
Why does February have less days than every other month even when it’s a leap year?
Partly to make it balance as explained in the video; and partly because Julius and Augustus Caesar were egotistical prats.
Because for the Romans it was an important month (purification) and when Caesar decided to change the calendar from a lunar one(28 days per month) to a solar one(30 days per month but adding 1 day more to some months) he decided to let february with 28 and use it as the month where a day would be added in leap years(they already added days to keep in sync with the seasons, the problem was that it wasnt something automatic but the job of the Pontifex Maximus (Caesar all that time) but if for some years he wasnt able to do so (like in the Roman civil war) then all the calendar went downhill very quickly
Has anyone noticed the creepers like at 1:36?!?!?
For my D&D game we use a lunisolar calendar that always starts the month over on the first day of the full moon, and the year starts over on the first full moon following the winter solstice.
RUclips: lets recommend this at 11:15pm on February, 28th :)
AGRICULTURAL REVOLUTION ON CRASH COURSE! HAHA! I have no clue why I find that so exciting.
Tomorrow is leap day!
+RainTeamTrain I am, still none the wiser, Happy Leap Year Day
Alright before i watch the video, ima say what others have told me, even though it is very likely *wrong*.
*a leap year adds and extra day because every year is not 365 days, but 365.25 days. so that means that every four years it would add up to 367 days.*
Sorry, 366 i mean
+Seteiris It might be 366.25 days
Sorry to correct, but to be even more precise, it's 365,24, and then even more numbers. This comment is not supposed to be offensive or rude, but to help others.
Thanks for the correction :D
9 days away for Leap Day 2020
1:20 cutie marks?
Here cause of miss angela
hi future programmers
Meant to comment yesterday on February 29 but I fell asleep now it’s March 1
"1 2 skip a few 99 100!" -Yacko, Animaniacs
Something as complicated as a leap year definitely needed an explanation! Thank you so much!
You think secular leap years are complicated, look at Jewish leap years, just a whole extra month added at what seems like random intervals
Protoss!!!
Yussssss!
Like if you know what I'm talking about.
FOR AIUR!!!!!!
Frank Hurley MY LIFE!!!!
Bitches don't know about my additional pylons!
Why not a calander wich is based on some distant constant and light speed, every time light passes this constant one time passes by.
And as an extra the time of the day .
Means after x hours its the date 9342.582 16:43
ANGELA YU send me here to watch your video
same 😆
3:12 China's giant hydroelectric dam must've had NOOOOTHING to do with that...
Huh?
@@samd2612 china made a really large hydroelectric dam which stopped the flow of a relaly big river which slowed the rotation of the earth by a few milleseconds
I've always been a fan of the 28-day month, 13-month per year calendar, with a 5 (or 6 for leap year) day new-year's holiday. This calendar also moves the beginning of the year back where it should be, the Vernal Equinox.
Coolio, maybe I'll come back in the next 4 years from now and see this comment again, probably not...
2:57 Well, no. The calendar drift has nothing to do with our measurement techniques. It's not a technological problem that you can science your way out of. As long as humans are living on earth, we will have to deal with it. And so leap years will continue to exist.
I love the tiny references, like the abomination from Warcraft 3 :D
i literally just noticed that and was finding the comment on it
CREEEPER!
Evan Barrie at 1:41
Why can't we have one calendar for every year?
Hear me out!
Just have the last day of the year last longer and even if you use the leap year system have the extra day at the end of the year instead of February. Then make January 1st start on a Thursday every year regardless of what day of the week the year ended. Why Thursday, so we can have a long new years holiday and back to work come Monday.
because living one 30 hour day wouldn't be ideal
A day is 24 hours long because that's the time it takes to make one rotation. If the last day is made 30 hours long, it might help keep the seasons in sync, but your day/night cycle will keep getting shifted by 6 hours each year before it syncs again after 4 years.... hope I am making sense... :)
jackrussel13
Take away making the last day longer part.
Just put the leap days at the end of the year and start the year on the same weekday is still a good idea.
For the Romans, the founders of our chalendar, the year originally ended with February (count it, September was originally the seventh month (septem = seven), October the eigth (octo = eight), November the ninth (novem = nine), and December the tenth (decim = ten)). So the leap day actually was added at the end of the year. The calendar was shifted because of the roman law, that said that gouvernors of all areas of the Roman empire (back then not yet an empire) had to come to Rome to account for their actions (and also elections, I think). The chalendar was shifted to make it easier for the gouvernors to travel. The Mare Internum isn't a place you want to be in the middle of around end February-begin March, it's stormy and dangerous. December on the other hand, gives you a relatively calm sea to sail on. This change in chalendar was just Roman problem-solving.
There is a proposal that's been floating around for awhile that is similar to this. It is called the World Calendar. It is set up so that each quarter year, the first month has 31 days, and the other two 30 days. In the middle of the year, between June and July, there would be a day with no numerical date or month, which isn't part of any week, called "World's Day". On years where we need a leap day, you add another similar "World's Day" to the end of the year. The benefit of this calendar is that every particular date always falls on the same day of the week, every month always starts on a particular day of the week etc. Of course, a lot of people don't like the idea of having days that aren't part of a week, it can screw up a lot of things, so the idea hasn't really caught on.

Warcraft Abomination at 03:04
Pudge?
Carl Lindberg *Timmeeeyyy*
I seriously don't recall if Pudge was from Wow or WC3
And part of the Starcraft 1 UI at 0:37 lol. That is the abomination from WC3 btw.
Bloodstainer
The original Pudge is from WC3 I believe. I don't know if WoW even have any DLCs
James Roy Ahmaogak TBC, Wotlk, Cata, MoP? Learn the definition of DLC.
I'm surprised I caught the Warcraft abomination
Leap day 2020 yay!
why didn't you upload this on 29 February...
haha I never knew about that crazy rules. I knew why there is a leap year but I really though they just left it at that :) God damn calendar designers, I have much more respect for them now.
