The Discordian calendar, as described on page 34
in the fourth edition of Principia Discordia.
Chaotic enough, it's quite simpler then the Gregorian calendar;
weeks are 5 days, and evens up on a year. Months are 73 days.
The leap day is inserted at the 60th day of the first month
(Chaos), giving the first month 74 days. The description of
the calendar is a "perpetual date converter from the gregorian
to the POEE calendar", so the leap years are the same as
the gregorians.
The Principia calls months "seasons", but for simplicity I
call them months in this calendar.
If anyone know more about how to treat the leap day - now it is
inserted in the month and week where it lands, rather then being
separated from month and weeks, I'm interested to know.
- Mirar, Pope of POEE.
