April (32 days) May (32 days) June (32 days) Grune (32 days) August (32 days) Spune (32 days) Sektober (32 days) Ember (32 days) December (32 days) Each week has eight days: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Octeday. Hogswatchnight The first of Ick is Hogswatchday, the Disc's New Year, and the winter solstice from the perspective of Ankh-Morpork. In the Astronomical Year the second midwinter (the year's midway point) is called Crueltide, but due to people using the Agricultural Year this is the same festival. The 32nd of December, or the day before the New Year, is known as "Hogswatchnight". Traditionally associated with pig-killing, to ensure there is enough food for the rest of the winter. Many Hogswatch traditions are parodies of those associated with Christmas, including a decorated oak tree in a pot, strings of paper sausages, and, of course, a visit by the Hogfather. Witches do not leave the house on Hogswatchnight more because of tradition than any practical reasons. The witch Nanny Ogg gets around this by simply inviting everyone to her house for the holiday instead. In the Omnian religion, Hogswatchnight is called the Fast of St Ossory. Omnians celebrate with fasting, prayer meetings, and the exchange of religious pamphlets. Hogswatch was also a holiday celebrated in The Dark Side of the Sun, a non-Discworld book by Pratchett. The Glorious Twenty-Fifth of May The 25th of May is quietly celebrated by the survivors of the People's Revolution, which ended the reign of Lord Winder. They wear a sprig of lilac and gather at the Small Gods Cemetery to honour the Watchmen who fell: Cecil Clapman, Ned Coates, Dai Dickins, John Keel, Horace Nancyball, Billy Wiglet, and (albeit temporarily) Reg Shoe. In the Roundworld (following Terry Pratchett's diagnosis of Alzheimer's disease), Match It For Pratchett called on fans to wear lilacs on 25 May in support of Terry. The slogan of the People's Revolution is "Truth, Justice, Freedom, Reasonably Priced Love, and a Hard-Boiled Egg!" Usage The calendar in general use in the Sto Plains and Ramtops ("Ankh-Morpork years") uses the agricultural year, and counts from the founding of Unseen University. Years and centuries are also given names by the UU's astrologers. 2005 AM, for instance, is the Year of the Prawn, the fifth year of the Century of the Anchovy. The majority of the Discworld novels are set in the 20th century AM,
