Picked this up from my other half seen on Facebook. I'm about to burst your Doomsday bubble. For all you Doomsdayers out there. There have been about 514 leap years since Caesar created it in 45BC. Without the extra day every four years, today would be 28th July, 2013. Also, the Mayan calendar did not account for leap year so technically the world should have ended 7 months ago.
