Most of you do realize that the Mayans calender has already finished. The Mayans believed the world spins around the earth only a 365 days, our current calender says no that's not true its 365.25 which is why we have leap years, and this is excluding many other things about our calender. Doomsday already had happened a long time ago. So chill and don't prepare yet for doomsday and buy your self a nice TV or something :P
