Analysis:

The twelve constellations in the modern west originated from the astrology of Babylon.

So the Babylonian calendar is used, and the Babylonian calendar is a lunar calendar (based on the change of the moon), so it is different from all calendars used now.

Babylon national calendar

Even as early as prehistoric times, following the footsteps of the past, people can already know when to hunt migrating wild animals and when to find shelter for the coming winter. But just before the highly civilized Tigris-Euphrates river basin appeared, the real calendar system appeared for the first time because of the need to decide what crops to plant or prepare for the flood period.

Around 2000 BC, the Babylonians designed a calendar according to the average period of two new moons of 29 1/2 days. In this calendar system, a year is divided into twelve lunar months, totaling 354 days. Because this algorithm is less than the solar day 1 1 day, the harvest festival will be held in the wrong season soon. In order to ensure the correct relationship between festivals and seasons, the priest suddenly came up with a set of methods that are still in use today-leap method, which corrects inconsistent astronomical cycles by adding extra days or months to make the calendar system and natural festivals harmonious. At first, the addition of months was based on the pleasure of the priest, but it soon appeared in a certain program: seven extra months were scattered in the loop of 19, so that the months and years were synchronized. The Babylonian calendar is a model of Hebrew origin and hijri, but both of them have undergone a major change: Jews adopt seven days a week-a time unit equivalent to a quarter of the lunar calendar; However, followers who use hijri abandon the revised calendar and use the lunar calendar purely, which is still the case today.
