Who can tell me the calendar of the Zhou Dynasty?

The calendar of the Zhou Dynasty is the solar calendar, that is, according to the sundial, the earth is first regarded as a stationary point, and then 365.25 days are divided into four seasons: spring, summer, autumn and winter, cold, wind, slow, hot, rain, dryness, Tibet, health, growth, harmony and formation. It can be seen that the importance of the Zhou calendar lies in determining the division of seasons according to the growth cycle of animals and plants on the earth.

The reason why the weekly calendar is a solar calendar is because it is marked by the "Winter Solstice Festival". In fact, so is the winter solstice festival.

The sun moves to the southernmost end of the relative earth movement cycle, and after the winter solstice, the sun begins to move northward relative to the earth. Therefore, Zhou people regard the winter solstice as the beginning of a new year, and divide a solar year into 24 solar terms, with two solar terms per month.

The summer calendar is the current lunar calendar, which is also called the lunar calendar because it conforms to the season of agricultural cultivation. The Shang calendar takes December of the current lunar calendar as the first month, which is one month worse than the summer calendar; The weekly calendar takes 1 1 month of the current lunar calendar as the first month, which is two months worse than the summer calendar.
