Discordianism Holyday Syaday
The Discordian calendar has five 73-day seasons: Chaos, Discord, Confusion, Bureaucracy, and The Aftermath. The Discordian year is aligned with the Gregorian calendar and begins on January 1, thus Chaos 1, 3173 YOLD (Year of Our Lady of Discord) is January 1, 2007 Gregorian.
There are Apostle Holydays on the 5th day of each season, named after the 5 Discordian apostles: Mungday, for Hung Mung; Mojoday, for Dr Van Van Mojo; Syaday, for Sri Syadasti; Zaraday, for Zarathud; and Maladay, for Malaclypse the Elder. There are also Season Holydays on the 50th of each season: Chaoflux, Discoflux, Confuflux, Bureflux, and Afflux.
May 31 is the 151st day of the year in the Gregorian calendar, and the Discordian Holyday of Syaday or St. Gulik
depending on whom you believe (5th day of the season of Confusion, honors Apostle Sri Syadasti)
About Sri Synaday
Sri Syadasti Syadavaktavya Syadasti Syannasti Syadasti Cavaktavyasca Syadasti Syannasti Syadavatavyasca Syadasti Syannasti Syadavaktavyasca (commonly called Sri Syadasti) is an Indian Pundit and Prince, born of the Peyotl Tribe, son of Gentle Chief Sun Flower Seed and the squaw Merry Jane. Patron to psychedelic type Discordians. NOTE: Sri Syadasti should not be confused with Blessed St. Gulik the Stoned, who is not the same person but is the same Apostle.
His name is Sanskrit, and means: "All affirmations are true in some sense, false in some sense, meaningless in some sense, true and false in some sense, true and meaningless in some sense, false and meaningless in some sense, and true and false and meaningless in some sense."
This Holiday is celebrated by altering your own consciousness in any way that is permissible to your superego and repeating the following affirmation 666 times: "Sri Syadasti Syadavaktavya Syadasti Syannasti Syadasti Cavaktavyasca Syadasti Syannasti Syadavatavyasca Syadasti Syannasti Syadavaktavyasca"
Modes of celebration
Discordian and other Holydays may be celebrated in a number of ways. One way is to go around, either in normal clothing or in robes of some sort, or perhaps naked, and hand out Pope Cards. Another way is to play an Erisian game, such as Sink or Discordian Mornington Crescent (though the latter is usually reserved for Eye Day). Yet another is to ignore the Holyday completely and act as if it did not exist. The best way is probably to avoid doing what this paragraph and this sentence say, reaffirming the Fifth Commandment which states that "A Discordian is Prohibited of Believing what he reads.".
The fact that there never was such a person as Sri Syadasti doesn't change any of this according to Discordians.
