Leirian calendar

The Leirian calendar, a lunar calendar used in Elendar, is a calendar using the lunar cycle of 31-day months resulting in a lunar year of 372 days, 4 days more than the solar calendar.

Etymology

The Leirian calendar takes its name from the goddess Leira, one of the three primary lunar deities. The irregular (with relationship to the solar calendar) nature of the lunar cycles is said to be related to Leira's reputation for loving randomness and trickery.
