The Religious Calendar of the Ruzi
The Standard Calendar of the Aznowa Confederation
The Standard Calendar of the Aznowa Confederation was a Solar Calendar that had 12 months of different lengths. Every 3rd year an intercalary day was added to the last month of the year. This calendar used a week of 7 days.
The days of the months were as following
- 27 days: 2nd, 4th, 5th, 8th, 10th, and 11th month
- 28 days: 6th and 12th month, except in leap years
- 29 days: 1st, 3rd, 7th, 9th, and 12th month in a leap year.
The calendar had a total of 334 days, with 335 in leap years.
The Qakhomatzian Calendar
The Qakhomatzian calendar was a semi-lunar calendar of 11 months of 29 days, except for the first and last month of the year. To keep the calendar in sync with the stars, an intercalary month would be added by royal decree. Most years therefore had 317 days, with the odd leap year enjoying 356 days. Like the Aznowa calendar, each week had 7 days.
The Zjonyo Calendar
The days of the months were as following:
- 30 days: 2nd, 4th, 5th, 6th (except in a leap year), 7th, 8th, and 10th
- 31 days: 1st, 3rd, 6th (in a leap year), 9th, 11th
After having been in use for almost 360 years, it was obvious that this calendar drifted compared to the stars. To deal with this drift, 622 a.Q. had 1 day added to each month, with 1 additional day added to the 4th month, making it also 32 days long, which made 622 a.Q a 346 days long year. The year after, the current calendar was introduced.
The Illome Calendar
The current calendar, the Illome calendar, is a lunisolar calendar. Since its introduction in 623 a.Q, the calendar is calculated to only having drifted ahead of the stars by half a day in 490 years.
