Hi Dan

what do you think of Issac Asimov's calendar?

The simplicity is quite stunning to me.

The Asimov calendar is fine if you like 13 of something in a period, and 7 of something else in another, which means it's not really fine. Even if you keep 7-day weeks, 13 weeks aren't easily divisible and are probably too long for fiscal periods (salary, rent, etc.).

Hi Paul

7 x 13 = 91 x 4 = 364 plus year end reconciliations to the solar and lunar cycle

x 8 to get lunar cycle so 2912 days or 56 lunar x 52 solar days

very simple very efficient

my birthday is 20th march who knows what day this will fall on?

It is day 79 season 1 always and forever in the Asimov calendar

i like this because i never remember birthdays

If you want 7 and 13 in there, might I humbly suggest 13 months of 28 days each, plus one extra? That way the lack of divisibility is confined to the year instead of the months.

It no longer correlates with the seasons as well, but given how much they vary over the globe, that may not be a problem. Presumably everyone would remember when their seasons were on the calendar...

There are a bunch of interesting smooth numbers just below 365, especially 360 = 2^3 * 3^2 * 5, 361 = 19^2, 363 = 3 * 11^2, and 364 = 2^2 * 7 * 13. Perhaps some of these cycles may prove interesting.

Well, the 52-week (364-day) approximation of a year is already fairly common. For example, my stated "annual" salary is actually that for 26 biweekly pay periods, and I get an "extra" 27th paycheck in 8.875% of years.

But please, start a new thread for this discussion, and leave this one for lunisolar calendar proposals.

Doesn't Oschkar have a lunisolar proposal too? I recall he's mentioned it, but don't recall him having written it up anywhere.

Is the topic of this thread supposed to be the Hebrew calendar only, or lunisolars in general? If the latter, I should probably write something up on the Chinese calendar too.

It would seem not, since it's not lunisolar.
