Discworld calendar

This article is about the counting and naming of years and days on Discworld. For calendar books like the Discworld's Assassins' Guild Diary 2000 see Bibliography.

General

A Discworld celestial year has 800 days and because of some interesting astronomical facts two of each seasons (two summers, two winters, etc.). This leads to the fact that many people actually do not count the astronomical years, but the half-years with 400 days, often refered to as "common years". The half-year has 13 months: Offle, February, March, April, May, June, Grune, August, Spune, Sektober, Ember, December, and Ick. Each month except Ick has 32 days, Ick has 16 days. Each week has eight days. The eighth day of each week is called Octeday.

There are two main calendars in use on Discworld. The Ankh-Morpork Calendar counts full years and starts at the founding of Ankh-Morpork, the University Calendar starts at the founding of Unseen University (in 1282 AM) and counts in half-years. Oddly enough, while the Imperial Ankh-Morpork calendar offers intellectual purity and mathematical elegance, the general populace tends to use the Weird, Wild, Wacky Wizards' calendar, which happens to correspond to the growing season.

Years and centuries

Centuries and years are named. We are currently in the Century of the Anchovy (Carpe Jugulum). It was preceded by the Century of the Fruitbat (Moving Pictures) and even earlier by the Century of the Three Lice and the Century of the Cobra (Small Gods). 2007 is the year of the Reversed Ptarmigan.

Notable past years

• The Year of the Lenient Vegetable - in which Bishop Kreeblephor converted a demon to the Omnian faith;
• The Year of the Pensive Hare - the events of Unseen Academicals take place shortly after the New Year celebrations which usher in this year.
• The Year of the Astounded Beetle ‎;
• The Year of the Notional Serpent ‎;

Special holidays

• Hogswatch (first of Ick, start of year)
• Soul Cake Tuesday
• Day of the Lesser Gods (?same as below?)
• Eve of Small Gods, first midsummer day
• Samedi Nuit Mort (celebrated in Genua)
• Creator's Birthday (28th of April)
• Wear a lilac if you were there day (25th of May)
• Koom Valley Day (5th of Grune)
• Crueltide, half-year point (end of first half-year, start of next)
• Alls Fallow, 3/4 point of 800-day year, the one day when witches and warlocks stay in bed (parodying Halloween), though in Wyrd Sisters, Esmerelda Weatherwax suggests that Hogswatch is the one day witches shouldn't go out, though this may only apply to Mistress Weatherwax, since her arrival may cause people to feel wary rather than jolly.

Seasons

• Spring Prime, first spring
• Summer : mid-point Small Gods' Eve
• Autumn Prime, first autumn
• Winter Secundus aka Spindlewinter : Mid-point Crueltide
• Secundus Spring
• Summer Two : mid-point All's Fallow
• Secundus Autumn
• Backspindlewinter : mid-point Hogswatch

Discworld seasons are 'explained' in one of four paragraphs in the footnote on page 5 of The Colour of Magic. It is written:

"Since the disc's tiny orbiting sunlet maintains a fixed orbit while the majestic disc turns slowly beneath it, it will be readily deduced that a disc year consists of not four but eight seasons. The summers are those times when the sun rises or sets at the nearest point on the Rim, the winters those occasions when it rises or sets at a point around ninety degrees along the circumference."

Zodiac

The Discworld zodiac consists of 64 (8*8) constellations, nebulae or individual stars grouped in thirteen Houses. There may be other constellations that are not part of the zodiac, but it's possible that the Discworld's unusual revolution means that the Discworld sun and/or moon enters all constellations at least once (the "zodiac" is a list of constellations in which the sun or moon [or planets, but there don't seem to be any around Discworld] can be found at some point in time). Roundworld has 88 constellations (1 of them non-contiguous), 12 of which are in the zodiac (a 13th constellation is also technically in the zodiac, but is not recognized as part of the zodiac).

Annotations

• Wezen the Doubleheaded Kangaroo: the first constellation (interesting because the wizards don't seem to recognize a kangaroo when they see it in The Last Continent-- perhaps because it was flattened and had only one head? Although in fairness you couldn't recognize anything else from it's constellation either, and it's never really obvious what is mythical and what isn't!)
• The Two Fat Cousins: possible reference to Tweedledee and Tweedledum?
• The Flying Moose: possible reference to Rocky The Flying Squirrel and Bullwinkle J Moose
• The Small Boring Group of Faint Stars: Rincewind's birth sign, usually not a wizard's sign. Was much brighter thousands of years ago when the Disc was closer to it (according to The Last Continent), so it's not clear why the ancients called it "faint"; perhaps they knew the Disc would move away from it long-term?
• The Knotted String: possible pun on "I'm a frayed knot" jokes
• Gahoolie the Vase of Tulips: the last constellation (now if we could only find that whale)
• the Triangle, mentioned in The Last Continent, possibly not part of the zodiac
