Year 634, 1658, 1999. There all been wrong. But according to The Dresden Codex, also known as the Codex Dresdensis The end of the world will come 21 dec 2012.
That’s not really true tbh. The only reference by the Mayans to 2012 is in a partially defaced stone inscription which says:
“The Thirteenth Bak’tun” will be finished (on) Four Ahaw, the Third of K’ank’in. ? will occur. (It will be) the descent(?) of the Nine Support (?) God(s) to the ?.”
Whatever happens on the 21th you better be ready. I know I am: https://blackmoore.wordpress.com/2012/10/27/my-morbid-facination-for-the-post-apocalyptic/
