How many days were there in ancient Greece?

The ancient Greek calendar is a kind of lunar calendar, with the summer solstice as the beginning of a year, and the summer solstice from the summer solstice to the next year as 1 year, while the month adopts a new moon [that is, 29.5306 days], the big month is 30 days, and the small month is 29 days, usually alternating in size, and there are also continuous big months, so1February is about 354 days.

In 334 BC, Calippe proposed a new law. He takes 19 as four times, that is, 76 years as a cycle. In this cycle, the total number of days is reduced by 1 day compared with the four times of Mo Dong's composition. That is to say, it took him 76 tropic years, including 940 moons and ***27759 days, which is called Kalipei Week and its correspondence. In 125 BC, Hipacus found that the length of the tropical year and the lunar month used by Kalipei was too long, so he subtracted 1 day from the four times in Kalipei's week, so that there were 3760 lunar months in 304 tropical years,1kloc-0/035.
