First a reminder of the harmonics:
The three moons of Unity cycle in a 1:2:5 harmonic orbit, with 48 local days between full moons. The year is 432 days long, and so the middle moon divides that year into 9 perfect segments.
The calendar:
The conventional month is 24 days long, half a "long-month", or two phases of the blue moon. There are 18 such months in a year, each month is divided into 4 weeks of 6 days. Every month represents a half-orbit of the middle moon. That's it... that's the entire calendar. There are no leap days, no irregularities.
A reminder of the seasons (on Unity):
There are three major (4-month) and three minor (2-month) seasons in alternation. Starting with winter, a major season: winter, thawing, spring, heat, descent, fall, winter, and so on.
The heat is the peak of the year, but only lasts for two months.
The descent marks the typical months when most places get the most rain.
Fall is fall
Winter is winter, and the new year begins the moment it ends.
Thawing leads into the spring (fertility) months
The spring is a gradual incline, culminating in the heat.

For Mars, the calendar is tracked the same as on Unity. For Viden, only local events are tracked relative to local horology.
