A Whollyday occurring on 49 Chaos aka 18 February.
Celebration
Honor The Mary, who is Patron Saint, Illuminated, of Bearers of Erisian Tattoos, and also Keeper of the Holy Chao Belly (rub it for good luck--with permission, of course). This is a good day to do something for a Mary, do something Merry, or even to Marry someone. (If you are merry about marrying a Mary, you earn extra points)
This holyday was created by the Discordian Division of the Ek-sen-triks CluborGuild and occurs in many discordian calendars, Principia Harmonia and Ek-sen-trik-kuh Discordia: The Tales of Shamlicht.
