Explanatory notes:
The calendar round comprises two calendars: a religious calendar which repeats every 260 days, and a solar calendar which repeats every 365 days (corresponding to the number of days the Earth takes to orbit the Sun). Both calendars repeat every 52x365 = 73x260 = 18,980 days. In the religious calendar, the days are cyclicly numbered 1-13, and named, in repetitive order with one of the twenty day names. The solar calendar is divided into 18 months of 20 days plus one month (Uayeb) of 5 days.
The Lord of the Night is an additional cycle of 9 days. Thus, the day number, day name, day of the month, month, and Lord of the Night repeat only every 9x52x365 days, or every 468 solar years of 365 days (which equals 657 religious years of 260 days).
JD 584,283 = 13.13.0.0.0.0 is used to correlate the Mayan and Julian calendars. This is yields the same day number and day name used in modern times by daykeepers in the highlands of Guatemala.
