Mayan calendar: Difference between revisions

J's <tt>todayno</tt> counts days from January 1, 1800. And, each of these date formatting routines expects a number generated by todayno, with hard coded offsets, if necessary, to make this work. (The lord of night number uses an offset of zero, in this context.)

Also, in haab, our 'chum' days are zeros from modulo arithmetic (and, thus, belong to the previous month).
