Discworld calendar

This article is about the counting and naming of years and days on Discworld. For the calendar-like-books, like Diaries, see Bibliography. For the commercial wall-calendars, see Discworld Calendars.

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, listed below. 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).

In Feet of Clay Doc Pseudopolis, President of the Guild of Gamblers, says “in a few years it’ll be the Century of the Rat.” No-one objects to this, but subsequent Discworld novels that mention the century refer to the Century of the Anchovy, perhaps suggesting that centuries are not named that far in advance (and that this is a bet Doc has lost).

• The Century of the Summer Weevil (mentioned in Unseen Academicals)
• The Century of the Dragonfly (mentioned in Reaper Man)
• The Century of the Cobra (mentioned in Pyramids)

Months Of The Discworld Year

Or rather, of the Discworld's half-year. The Celebrated Discworld Almanak clarifies previously opaque or puzzling aspects of the calendar. Quote:

This be for the Common Year, that being the four hundred days that measure the Season from Winter's Edge until the snows come again, and the Hogswatch is celebrated. All Celestial measurements, Observations and notations of Stars, houses of the firmament, and other divers heavenly bodies are taken on the Full Celestial year, of eight hundred days, which emcompasses two common years...

• Ick - only has sixteen days
• Offle - all following months have thirty-two
• February
• March
• April
• May
• June
• Grune
• August
• Spune
• Sektober
• Ember
• December

The year commences on Hogswatch Day and ends on the following Hogswatch Eve.

Inconsistencies with the order of months

None of the books mention the specific order of the months or dayes of the week, so we are left with secondary sources - which are not always consistent. Of note, various editions of the Discworld Companion (right up to The Ultimate Discworld Companion), as well as the Discworld Roleplaying Game, specify that the year begins with Offle and ends with Ick. Neither of those sources give a date for Hogswatchnight, but the roleplaying game does specify its the last night of the year, so presumably in that calendar it occurs on the 16th of Ick, rather than the 32nd of December. (See also Crueltide.)

Special holidays

• Hogswatch Eve, the end of the old common year.
• Hogswatch Day (first of Ick, start of the new common 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). According to research wizard "Numbers" Riktor, who meticulously counted them, there are, or were at the time of counting, 49,873 visible stars in the Discworld heavens. Which is ample raw material for the cosmic Rorschach test that creates constellations.

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 its 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
