Hi Jack and everyone else here,
See my July 2009 post relating to this very subject (
http://projectavalon.net/forum/showp...6&postcount=46). Also check out my links in that post, as I believe this will give you a much more balanced view on the Mayan Calendar and End Date than you will get from either Ian Lungold or Carl Johan Caleman (Lungold's mentor).
Best wishes
