On behalf of the Maya, welcome to the 14th...um...what's the "annual" equivalent of 400 years? tetra-centennial?...B'ak'tun!!!
It's the last one for 394 years, so come relax, grab a seat on the pyramid, fill up your gourd with balche (http://en.wikipedia.org/wiki/Balch%C3%A9), and enjoy the festivities (and watch the world NOT end), because this ain't coming around again until March 26, 2407 =D
When putting down today's date, you can simply put "13.0.0.0.0" and you're good to go, should you be so inclined
Sorry...my archaeology is showing =p
