[Aztlan] 13 BAKTUN Date

[Sid Hollander]

Depends on what the correlation factor is.   Correlating dates between
calendars are accomplished by passing through a 'standard' calendar called
the Julian Day Number.  This count, Invented by a fellow named Seeger was
named in honor of his father (Julius).  This is merely a numbering of the
days (much like the Maya LC.  It started on at noon of Jan 1, 4712 BC.  The
starting point was selected by coordinating 3 other cycles and projecting
backwards to a point in the past prior to any other calendar systems.

So if you  imagine the count sequencing  1, 2, 3,...98,99,  100.  If on that
hundredth day a Maya in Meso America woke and said, Today I will start the
Maya Long Count and define today as day 0.  (No days have elapsed.  On an
aside, we currently use elapsed and non-elapsed time concept.  Consider the
following statement. "The time is 1 o'clock A.M. on July 1"  In the first
part One hour has elapsed and IN the 2nd hour of the day.  In we are IN the
first day of the month ).  So the two systems are in parallel but off-set by
100 days. From this you get  the AHAU EQUATION..

JDN - 100 = MAYA  LC    or             MAYA + 100 = JDN

So the whole deal is based upon the "100",     The coefficient of
Correlation.   For sure it was not 100.  Depending upon who you ask you will
get different numbers.  Most will select either 584,283  or 584,285  and
there-in is your two day difference.

If you are doing this as a commercial type thing then I'd use the one that
will be most popular and that is the one that falls on 21st.  i.e "Ending on
the equinox"   On the other hand you can give user the option of which
correlation to use.
