We've heard a lot lately about the Mayan calendar ending this December which, according to some, means that will be the end of the world. There was even a movie about it.
Unfortunately for the "doomsdayers" out there, the Mayan calendar didn't have leap years, so since one of the Roman Caesars created leap year in 45 B.C. there have been about 514 leap years, which would make this July 28, 2013.
