[Aztlan] Astronomical basis of Long-Count/2012

[John Major Jenkins]

I'm sure Robert Hall would agree. He noted the conjunction cycles of Jupiter and Saturn and suggested many years ago that it might have served as a basis for the katun period in the Long Count. Susan Milbrath also discussed this in her book Star Gods of the Maya. The 3 katun cycle of Venus phenomena has also been noted.

>The synodic cycle of Jupiter and Saturn averages out to a mean of 7254 days.
