Well, the 13th b'ak'tun ended yesterday and nothing happened.
Happy 18.104.22.168.1! It's the first day of the 14th b'ak'tun--a new Maya era.
Looking forward to the next Maya apocalypse? Mark your calendars. The 14th b'ak'tun ends Monday, March 26, 2407. The first piktun (20 b'ak'tuns) ends Friday, October 13, 4772.
Friday the 13th...look out! That day should be really unlucky!
