The four quarters of the year are also arranged so that they roughly represent the Spring, Summer, Autumn and Winter of Earth's northern hemisphere, although the leap week rule can sometimes result in up to 2 weeks deviation from the Earth meteorological calendar.

	This design is intended to make sure that December 31 will always be in week 43 of the subspace calendar (the last week of Jovus), and therefore will always occur between 22 Jovus and 28 Jovus of each year. This was done to ensure that the Christmas holiday (which will eventually have a functionally equivalent festival in the Intryon universe) is always at the same time each year (at the end of Jovus, in weeks 42 and 43).

	The start date for the calendar is 1~~-A-~~2000, which is the same date as Monday 6 March 2000. This makes 1~~-K-~~2000 equal to Monday 1 January 2001. The last day of the year, 28~~-L-~~2000, is equivalent to Sunday 11 March 2001; the subspace year 2001 then starts on Monday 12 March 2001.		The start date for the calendar is 1 Astrus 2000, which is the same date as Monday 6 March 2000. This makes 1 Karus 2000 equal to Monday 1 January 2001. The last day of the year, 28 Liminus 2000, is equivalent to Sunday 11 March 2001; the subspace year 2001 then starts on Monday 12 March 2001.

	The mechanism to determine if a particular year is a leap year is basically as follows: Get the day-of-the-week of the Gregorian calendar's December 31 for both the year being checked and the year after it. If the year you want to check has a day-of-the-week that comes later than the following year's day-of-the-week, this year is a leap year.

	The names of the months were derived from Latin~~. They were chosen so that they~~ start with the first 12 letters (A through L). Written dates can then simply use the letter for the month, which avoids the confusion of date ordering (10-A-8000 and A-10-8000 are not ambiguous, whereas 10-1-8000 and 1-10-8000 are). This also lends itself well to computerized date ordering, which can be formatted as YYYY M DD for easy sorting, using the letter (since this will still sort) and remaining unambiguous.
