Displays the current date according to the Discordian (or Erisian) Calendar, as described in Principia Discordia. It shows the current season, day of the week and year, and includes the eleven official Discordian holidays.

The Discordian Calendar is composed of five seasons of 73 days each: Chaos, Discord, Confusion, Bureaucracy, and The Aftermath. It is aligned with the Gregorian calendar, with Chaos 1 always matching January 1st. Year 1 in the Discordian Calendar is equivalent to year 1166 BCE in the Gregorian calendar.

The Discordian Calendar is also divided in weeks of five days each (Sweetmorn, Boomtime, Pungenday, Prickle-Prickle, and Setting Orange).

In addition, once every four years (on leap years in the Gregorian calendar), one extra day is added to the Discordian Calendar between Chaos 59 and Chaos 60, matching February 29th. This day (known as St. Tib's Day) does not fall in any of days of the week.
