Tutorial Calendar

This example Calendar shows the pieces a calendar can carry: months, seasons, an optional named week, and optional holidays.

Months

This calendar has twelve months of 30 days each, for a 360-day year. Months are listed in order, and their days should add up to the world timeline’s year length. A month can also carry a short abbreviation (such as “FRM” for Firstmoon). A month flagged intercalary sits outside the numbered months — a real day of the year that has no weekday and does not advance the weekday cycle.

Seasons

Four seasons mark where spring, summer, autumn, and winter begin. Each season’s Northern and Southern Hemisphere names are opposites — when the north is in summer, the south is in winter.

Week

An optional, ordered list of weekday names — here a five-day week. starts_on sets which weekday the calendar’s first counted day (year 1) falls on; here the year opens on Onesday. The weekday cycle runs continuously across years and skips any intercalary days, which carry no weekday and don’t advance it.

Holidays

Optional recurring dates and festivals, each with a category (religious, historical, civic, seasonal, geographical, cultural, astronomical, dynastic, agricultural, or commercial). This calendar has one example, Founding Day.

Leap years

Optional leap rules make some years longer. You can stack more than one. Here two rules both run every fourth year, when Secondmoon and Eighthmoon each gain a day (31 instead of 30). Unlike an intercalary day, a leap day is a normal day — it has a weekday and the cycle counts through it.
