Moonkey & Meyer-Palmen 6840-year cycles RE: Month Names for the Lunar Olympiad Calendar
Dear Calendar People
The two cycles differ by the number of days in them.
While the Meyer-Palmen 6840-year cycle has exactly 2498258 days, the Moonkey 6840-year cycle, which follows the 33-year cycle, has 6840*12053/33 = 2498258 2/11
days and so is 2/11 day longer. The 2/11 day can be eliminated by restarting the 33-year cycle after 6840 years. The last 33-year cycle is then truncated to 9 years, like in Walter’s suggested 900-year cycle.

As a Solunar epact-based calendar system (using figure 2 at the above link) this Moonkey system has the advantage that all lunations
are either 29 or 30 calendar days in length (unlike the Meyer-Palmen and Gregorian lunar calendars which have, for instance, 31-day lunations).
Coincidentally, I have just recently made available my design for a Moonkey Easter Computus for the Dee-Cecil (and Dee) calendars,
implemented as a cylindrical table for the 6840 years from AD 1572 to 8411. There are two sizes available for download (by clicking the red down-arrows at right) as pdf files (MoonkeyYrs17med and MoonkeyYrs17small) at the foot of
The "med"(ium) size version prints on US legal-sized paper and is intended for mounting on a Trader Joe's coffee bean can (12 oz.
The "small" version prints on US letter-size paper for mounting on standard 3-inch diameter cardboard mailing tube cylinders. This
small version includes triplicate collars to allow some practice at cutting out the collar's fiddly key-shaped Sunday-letter decoding window.
