International Fixed Calendar





RULES

The calendar year has 13 months each with 28 days plus an extra day at the end of the year not belonging to any month. Each year coincides with the corresponding Gregorian year.

The months are named the same as for the Gregorian Calendar except that a month called ''Sol'' or ''Midi'' is inserted between June and July.

In Leap Year s, a Leap Day , also belonging to no month is inserted between June and the new month. Common Year s are 365 days long; leap years are 366 days long.

The first day of each year, January 1 , is deemed a Sunday and every subsequent day that belongs to a month is deemed to be in the conventional 7-day week (the days of which go, in order, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday, followed by Sunday of the next week).

Days that do not belong to a month are deemed to be outside the Week and always occur between a day deemed to be Saturday and a day deemed to be Sunday.

Since each month consists of exactly four weeks, the first day of each month and every seventh day after that for the rest of the month is deemed to be a Sunday, the second day of each month and every seventh day after that for the rest of the month is deemed to be a Monday, and so on. So each month begins on a Sunday and ends on a Saturday, just like each conventional week.

This causes all months to look like this:

The 13 months and extra days occur on the following Gregorian dates:
January Jan 1 - Jan 28 July Jul 16 - Aug 12
February Jan 29 - Feb 25 August Aug 13 - Sep 9
  • September Sep 10 - Oct 7

  • - Apr 22--- October Oct 8 - Nov 4

  • - May 20--- November Nov 5 - Dec 2

  • - Jun 17--- December Dec 3 - Dec 30

  • Leap Day June 17 Extra day December 31

Sol/Midi Jun 18 - Jul 15
  • These dates are a day earlier in a leap year
