I'd think so. You can't really have a separate Haab calendar, as a Haab date contains only "month" and "day"; no "year", which means that a Haab date does not define one unique day. Tzolkin dates are similar: only "week" and "day". Like the Gregorian 'year-month-day' calendar and the 'year-week-day' calendar, they're separate ways of counting days within the same calendar system. So you should probably make one module, which represents the date by the day number in the long count cycle, and calculate the Haab and Tzolkin names from that. Eugene
