All this crazy talk about the world ending on December 21, 2012 is ridiculous, mostly because grown-ass humans should know better than to actually believe that crap, but also because the major reasoning—that the Mayan Calendar ends on that day—is messed up. It actually ended in August, 2011.
Lemme drop some knowledge on you real quick.
The Mayan Calendar works in neat little integers.
This means they have divided up the year into equal, whole-number parts. That would be nice and convenient, but Earth doesn’t exactly work that way. The Mayan Calendar spells out 365 days to a year, but the real number is more like 365.25 days in a year. You can work a calendar just fine with 365 days in a year, but eventually your seasons will be thrown off and July will be in the middle of winter. Therefore….
Julius Caesar came up with Leap Days.
In 47 BC, Caesar told calendar makers to add one year every four years. This helps keep the dates in line with the seasons. So, in 48 BC, the Mayan Calendar was already off one day from the modern calendar. Then…
Pope Gregory XIII shaved some days from Caesar’s calendar.
In 1582, Pope Gregory, along with astronomer Christopher Clavius, chopped ten days out of October that year. They improved on the accuracy of Caesar’s calendar by further refining the length of a year from 365 days and 6 hours to 365 days, 5 hours, 49 minutes, and 12 seconds. This was all to make Easter realign with the spring equinox. As it was, the date had moved roughly 10 days, and Pope Gregory moved it back.
Let’s do some math.
It’s 2012, meaning 430 years have passed since the introduction of the Gregorian Calendar. We’ve had roughly 107 days added since then.
There are 1629 years between the introduction of the Julian Leap Year and the Gregorian Calendar. That’s about 407 days.
Added together and you get 514 days, and then we can take away those 10 days Pope Gregory lopped out of October in 1582. We’re left with 504 days that we have added to the calendar that the Mayan Calendar doesn’t account for.
The world is supposed to end on December 21, 2012. Let’s take out 366 days (2012 was a leap year) and now we’ve gone back to December 21, 2011. December 21 is the 355th day of the year, but we need to go back an additional 138 leap days. So the world should’ve ended on the 227th day of 2011, which is August 15th.
But I didn’t even account for how many days we lost in the transition from AD to BC.
And I didn’t account for any of the leap seconds we’ve added.
And I didn’t account for any of the leap days we actually didn’t add because you don’t add leap days on years that are divisible by 100, unless they’re also divisible by 400. (2000 was a leap year…1900 wasn’t.)
Basically, the Mayan Calendar already ran out at some point in summer 2011. And we’re still here. So stop talking crazy.
Unless you wanna say the world is gonna end because Snooki is having a baby because that reasoning I can actually get behind.
