Number 1 – The Mayan Calendar

In the conclusion to his famous essay (the one that set the whole 2012 ball rolling...) on how the Mayan calendar predicts startling, if not calamitous, happenings for the 21st December 2012, THE HOW AND WHY OF THE MAYAN END DATE IN 2012 A.D., published in December 1994, John Major Jenkins states:

This essay is not contrived upon sketchy evidence. It basically rests upon two facts:1) the well known end date of the 13-baktun cycle of the Mayan Long Count, which is December 21st, 2012 A.D. and2) the astronomical situation on that day. Based upon these two facts alone, the creators of the Long Count knew about and calculated the rate of precession over 2300 years ago. I can conceive of no other conclusion. To explain this away as "coincidence" would only obscure the issue. For early Mesoamerican skywatchers, the slow approach of the winter solstice sun to the Sacred Tree was seen as a critical process, the culmination of which was surely worthy of being called 13.0.0.0.0, the end of a World Age. The channel would then be open through the winter solstice doorway, up the Sacred Tree, the Xibalba be , to the center of the churning heavens, the Heart of Sky.

I hope this clears that one up for you all.
