Remonitionist calendars

Lunar

This is a variation of the Islamic calendar meant to take into account the Metonic cycle. Counterintuitively, the Remonitionist lunar calendar does so by shortening every fourth year by a lunar month. This way 20 lunar years are 235 months, the same as 19 solar years.

Solar

The Remonitionist solar calendar consists of 19 solar months, each with 19 days. Four or five additional days are inserted at the end of each year.
