MayaDate® is a calculator which is
intended for serious students of Mayan Calendrics. It is fully configurable
for those wishing to investigate alternative hypotheses. The
user can set the Long Count to modern calendar and Long Count
to Calendar Round correlations to any desired value.
The basic program function is to calculate the Base Date plus
Distance Number and the Base Date minus Distance Number. It displays
the results in both Long Count and Calendar Round. It also calculates
and displays the modern calendar date (Julian, Gregorian or Julian
Day Number), and all major sub-cycles such as the Direction /
Color, the God of the Night, and the day within the Calendar
Round, the Tzolkin, the Haab, and the 819-day cycle for each
of the three dates.
