The Simterran Year

The Simterran year is 365 days with 13 months of 28 days and an extra day at the end of the year. (The calendar is similar to the International Fixed Calendar of our world). Because of the nature of the calendar, the months and weeks are fixed with the 1st day always occurring on a Sunday and the last day occurring on a Saturday, with few exceptions.

*An intercalary day or leap day occurs once every fourth year and is commonly called Toad Hop. It is named for the elusive umai, a reptilian race. This extra day occurs during the month of Suluary (northern hemisphere) or Apollon (southern hemisphere), a month between February and March. The day is typically called Sunturday on the calendar so as not to disrupt the days of the week schedule and is always calculated as Suluary 29th (the 26th day of March on the Gregorian calendar).

**The final day of the year (inserted after December 28th and equivalent to December 31st) is called Year’s End (also New Year’s Eve) and does not belong to any week (though it is commonly calculated as December 29th). The day is typically called Sunterday, similar to Toad Hop.

Real-World Correlations

This chart over on my Google Drive shows real-world dates based on the Gregorian calendar, compared to dates on Simterra. Because Simterra has 13 months instead of 12, the zodiac signs have also shifted a bit. See more on astrological signs below.

Seasons

In the Northern Hemisphere, seasons are similar to Eorthe. Winter begins in December, spring starts in March, summer  kicks off in June, and autumn commences in September. There are four months of winter, three months of spring, three months of summer, and three months of autumn. In the Southern Hemisphere, the seasons are the opposite (and there are 4 months of summer). 

Seasons	Northern Hemisphere	Southern Hemisphere
Spring	March-May	September-November
Summer	June-August	December-Suluary
Autumn	September-November	March-May
Winter	December-Suluary	June-August
