Hey! Please also see "Calendar systems". I divided my thoughts and questions into two mails this time, because they're IMO not so directly related. Here are my first thoughts. Turn on a monospaced font to see some things correctly, please! As I already have said for the Daléian calendar, one Arecan year has about 455.75 days. That means all four years, one day must be dropped because you usually count with 456 days/year: each year +0.25 days. What I did not think about last time was what can be done with observing the moon. For the Daléian calendar, I had 18 months with an average of 25.333 days in 456d years (actually 25.3194444 when counting with leap and solar (?) years). So for the time being, I thought it would be quite interesting to have two moons -- though I haven't done my homework about how long the moons' cycles must be and how far they are away from the planet etc. etc. Without any scientific justification, I assumed Moon A to have 24-day cycles and Moon B to have 60-day cylcles. Furthermore, I assumed that the moons both have irregular orbits, like when drawing something with the Spirograph if you know that thingy. So Moon A needs ~1/4 year (455.75/4 = 113.9375 days) to be at the same position where it started and Moon B needs ~1/2 year (455.75/2 = 227.875 days) for that. These second cycles s/would be best called "big cycles" I guess, the month cycles "small cylces". Distinctive points then would then be (S = sun; P = planet; A = moon A; B = moon B; yrs = years; ds = days): [B] [B] [A] | | | (P) [A]-(P) [B][A]-(P) [B]----(P) | | | | | | | [A] | | | | | | | | ((S)) ((S)) ((S)) ((S)) 0 0.25 0.5 0.75 yrs 0 113.9375 227.875 341.8125 ds [A] | (P) (P)-[A] (P)-[A][B] (P)----[B] | | | | [A] | | | [B] [B] | | | | | | ((S)) ((S)) ((S)) ((S)) 1 1.25 1.5 1.75 yrs 455.75 569.6875 638.625 797.5625 ds That would mean there'd be a lunar and/or solar eclipse every quarter year? Is that much or is it the same with the Earth? But at the same place at the same time?! Would it be better to grow the "big cycles" rather to years than months? However, looking at this picture above, you could extremely well divide the year into 4 months, and have another period of 2 years. Maybe the standard period could be 2 years as well, because there are as I assumed no such seasons as on the northern/southern hemisphere? I hope you enjoyed.
