[Aztlan] 819day Count

[Ivan Van Laningham]

Hi All--
I've decided to post a paper, originally written in 1999, discussing
the 819-day
count on my website.  I wrote it for, and it was scheduled to be in, Volume
VII of _U Mut Maya_, sadly now defunct.  I've shared this paper with a
couple of others over the last few years, as I had intended it for eventual
publication, but this seems as good a time as any to make it public, as I
doubt that I'll have much else to say on the subject.  In it, I discuss the
cycle that both Cliff and I refer to as the "E-Cycle", along with the
mathematics involved, in which I am primarily interested.  Thus, you will
find no discussion of astronomical phenomena that may or may not contribute
to our understanding of the 819-day count.  I explore only the mathematics,
and why I think that the true base date for the E cycle is 1 Kaban 0 Pohp *
-4.13.5.9.3.*

The paper can be found at:

Note that it is as yet not tied into my Mayan calendar pages, so you must
have the link above to reach it.

Metta,
Ivan
