[Aztlan] Astronomical basis of Long-Count/2012

[Star Heart]

The following is a list of computer assisted Jupiter-Saturn conjunctions in
Julian Calendar dates and Long-Count dates.
Does anyone see a pattern? (Triple conjunctions are listed as one with an
(*) after the Long-Count date).

The synodic cycle of Jupiter and Saturn averages out to a mean of 7254 days.
This is clearly 54 days more than a katun (7200). On pp. 71-73 of the
Dresden Codex there is what has been called the 54-Series. This is
a compilation of multiples of 54 up until 702 (13 x 54). There continues
multiples of 702 until 14040 is reached (20 x 702 = 260 x 54). Higher
multiples of 14040 are suggested. The numbers 54, 702 and 14040 are
emphasized on these pages. These are the number of additional days of mean
Jupiter/Saturn synods for cycles of 1-katun, 13-katun and 13-baktun,
respectively. This indicates a verifiable astronomical basis for what the
Mayanists now call the "Long-Count" and specifically also the 13-baktun
cycle, such as the one anticipated to conclude on December 21/23, 2012. We
also have strong supportive evidence from an authentic Maya document.

Anyone care to agree?
