That’s not the only messed up clock… https://image.nostr.build/427a5158f6b532fd48c2c0ba4a84a957796f64b777c24cf56e0cabf2ac3369a7.jpg
Big if true….wasn’t the calendar modeled on moon cycles?
Apparently there are many types of calendars including hybrid 12 & 13 month long… “In a Metonic calendar (a type of lunisolar calendar), there are twelve years of 12 lunar months and seven years of 13 lunar months. In the Babylonian and Hebrew lunisolar calendars, the years 3, 6, 8, 11, 14, 17, and 19 are the long (13-month) years of the Metonic cycle. This cycle forms the basis of the Greek and Hebrew calendars.“ https://en.m.wikipedia.org/wiki/Metonic_cycle
International Fixed Calendar was used by Kodak… “By 1928, Kodak had implemented Costworth's calendar and Eastman himself took on the responsibility of promoting it to the world on his dime.” “Favored by leaders in transportation and logistics, the International Fixed Calendar was a favorite of Kodak founder George Eastman, whose company used it until 1989.” https://en.m.wikipedia.org/wiki/Metonic_cycle
