Calander of Martapa

So the calender...which I seemed to overlook...is as follows:
There are 365 days in a year. This is known thanks to the residents of Tayke.

There are 12 months of 30 days with 5 holy days.

The 5 Holy Days are each of the equinoxes and solstices, as well as Year's Renewal.

Weeks are 5 days long and termed a "a five day". Each month has six. Holy Days are not included in each month. They are separate.

Days are 24 hours long.

The day is broken up into: Sun Rising (6 AM is), Sun High (noon), Shadow Fall (5 pm ish), Dark (8 PM ish) and Full Night (Midnight).

Days of the Week are simply numbered.

Months: Cold Dark (Jan), Deep Snow (Feb), Melting Snow (march), River Rain (April), River Swell (May), Green Planting (June), Warm Sun (July), Sun Scorch (Aug), Harvest (Sept), Leaves Turn (Oct), Leaf Fall (Nov), No Grass (Dec).

So for example if you wanted to do something on the 1st day of the 3rd week of July you would say: On the 1st day in the 3rd week of Warm Sun.
