Version 2 of the Rational Calendar

My previous suggestion was too messy. Here’s how it should be, from the beginning:

• The 12 months are abolished. Day counts should follow seasons instead of pretending to follow the moon’s cycles.
• New year is fixed to the day of winter solstice. This day also marks the beginning of Winter.
• Each season is defined as 91 days long. The first day of Spring, Summer and Autumn is called the calendrical vernal equinox, summer solstice and autumnal equinox respectively (this distinction because the natural events may fall on other dates).
• 91 days times 4 seasons is 364 days. The extra one day (or the two in leap years) is a holiday.
• The week is also redefined, as 10 days long. The 10th day is a weekly holiday.
• The 91st day of each season is a seasonal holiday, and is outside the week system. 
• The annual holiday (or days) are outside both week and season systems.
• The 1st day of each season is a holiday as well, as this is the day of solstice or equinox. They are not outside week or season systems.

Here I’ve tried to visualize this:

The holidays line up in such a way that the transition from one season to the next is marked by a series of holidays, in ascending order (if you think of the rare as higher than the common). New year, for ezample, is preceded by three or four holidays: first a weekly, then seasonal, and finally the annual holiday or days. The moment of New Year is of course midnight between the last day and the day of winter solstice. And since the day of solstice is a holiday as well, New Year is associated with a four or five day vacation. Seasonal transitions are associated with a three day vacation.

This makes for a most orderly calendar. The only unknown is when leap years come in, as it is determined by the astronomical event of winter solstice. But this uncertainty is of minimal importance, as weeks and seasons are defined as unaffected.
