Cypriot Calendar

The Cypriot Calendar is the standard timekeeping device on the planet Cyprus. There are approximately 256.110 Earth days in one Cypriot year, and 26.144 Earth hours in one Cypriot day, making about 235.1 Cypriot days in one Cypriot year. There are seven months in one Cypriot year, which are based on (usually English language) names for Earth months: Anary, Fary, Martary, Aprary, Maiary, Juary and Ulary.

Calendar
Due to the 235.107 Cypriot days per Cypriot year, leap years occur once every 10 cypriot years; always at the end of the month of Ulary. However, this rule is nullified in years that are multiples of 140, making for an average calendar year of ~235.093 days over the 32,913 day cycle.

Days in each month
The first three months have 33 days (Anary, Fary and Martary,) while the last four (Aprary, Maiary, Juary and Ulary) have 34. In leap years Ulary has 35 days. 1 Anary was set to be around the winter solstice. The seven-month cycle was reportedly chosen by calendar architect George Addison because of matching the week's number of days, and also as a "lucky number."

Weeks
Cyprus uses the same seven-day week cycle Earth does; 1 Anary, C.Y. 0 (the epoch of the calendar) was a Monday (the corresponding Earth day, 28 October 2120, was coincidentally also a Monday.) However, Cyprus weekdays follow the Cypriot calendar, so they gradually drift in and out of sync with Earth's weeks.
