How many of you have come up with calendars for your cultures?
Do you base them on a 365.25 day year? Or do you invent your own astronomy to come up with different days?
Is is lunar? Solar? Both?
Do you have weeks? How long are they?
How many months?
How many seasons are there?
I just finished designing a calendar for one of my concultures. I have it set in an alternate solar system where there are 309.33 days in a year.
There is no moon, so months never evolved. There are 8 seasons instead, of 37 or 39 days each, depending on which part of the elliptical orbit the planet is. There are waxing seasons and waning seasons centered around either the equinoxes or the solstices. They do not count as falling in a season; they only mark the divisions, and they function as festival days. There is aslo a New Year's Day and (every three years) a Leap Day.
This totals up to 309 or 310 days a year. The date is given as days away from the nearest holiday, such as, it is the 31st day until solstice, or the 12th day since equinox.
They have weeks of 10 days each, and they rest on the 1st and 6th of each week. They skip a day of the week if there is no Leap Day that year, such that there are exactly 31 weeks in a year and holidays always fall on the same day of the week.
Anyhow, what about the rest of you? How much detail do you have?
