I've just created the calendar for Watya'iya`isa. W. is spoken on another planet, so it's based on different measurements than ours. This took me a few hours to work out. If you're interested, the day is 27 hours, 19 minutes, and 42.3 seconds; the year is 407 days, 19 hours, 55 minutes, and 4 seconds (Earth time). The calendar is a lunisolar calendar with 16/17 months. In the oldest (and by far simplest) of the systems in use is the 5-year calendar. In every 5-year period, the second and fourth years are 17 months and the first, third, and fifth are 16 months. In addition, every 75th cycle (375 years) has only one 17-month year (the third year). The months themselves are 22/21 days. In short years (16-month years), the first, ninth, and sixteenth months are 21 days; in long years (17-month years), the first and ninth months are 21 days. All other months are 22 days long. However, in the 12th cycle, the first short year has only two short months (1st and 9th). In addition, there are three newer calendars in use by different descendant-tribes. Five is considered an unlucky number, so there was a push to abandon the five-year calendar. The three others are: 3-Year A: 16-16-17, with the fifth cycle 17-16-17 (they couldn't completely avoid the number five) 3-Year B: 16-17-16, with the fifth cycle 17-16-17 6-Year, the most complicated (also, the one that stays closest to the five-year calendar): 16-17-16-16-17-16 followed by 16-17-16-17-16-17, these are repeated, followed by another 16-17-16-16-17-16 period (30-year cycle overall). 3-Year A is the furthest off from 5-Year, 2 out of every 3 years are one month behind (there have been proposals to add one month, making it one month ahead 1 out of every 3 years), the other 1 out of every three is even with the 5-Year calendar. All three of these keep the same method of determining the length of days. Also, all three keep the longer 375-year cycle, thus the 125th cycle of 3-Year A is 16-16-17, and of 3-Year B is 16-17-16; the six-year calendar also drops a month ever 375 years. Some have instead adopted a solar calendar of 358 days (10 months of 22 days, 6 months of 23 days), with a leap year every 6 years, unless divisible by 120. The humans use a 12-month calendar with 11 months of 30 days, and 1 of 28 (February, by tradition, also the month of the leap year). As soon as I work out names for the months of Watya'iya`isa, I'll post them. -- "A silent mouth is sweet to hear" - Irish proverb ICQ: 18656696 AOL: NikTailor
