Central Dzózó calendar

The Central dzózo calendar is a luni-solar calendar used in large parts of Dzózó. The names of months and days along with some other details are subject to local variations.

Months
The months of the calendar are based on the phases of Winter's smaller moon. Months are generally 10 days long with 11 day leap months being inserted three times along a 23 month cycle. The leap months are generally the first, 8th/9th and 16th/17th month of the cycle with the exact pattern varying regionally.

Intercalation
Regular years consist of 25 months. To prevent this period (253.25 days) from drifting out of sync with the shorter solar year (251.8 days), every 7th year is shortened to 24 months (243.12 days). This reduces the drift to just one day every 350 years.
