Year calendar
A jear may be subdivided into 2 years, a long year of 122 trips or 366 days followed by a short year of 121 trips or 363 days. Leap trips turn a short year into a long year.
Years may be subdivided into 12 months of either 10 trips (short month) or 11 trips (long month), i.e. 30 or 33 days. The sixth and, in long years, the twelfth month would be long months.
An even lunar year usually consists of 13 moons (351 days), whereas an odd one always has 14 moons (378 days). Every 40th lunar year (or every 20th even one) also has 14 moons, but every 400th lunar year has an extraordinary 15 moons. Thus, there are 211 extra moons (i.e. 14th and 15th) in every 400-year cycle.
