What day is September 10?

Weeks, also called weeks, are a unit of time and the basis for working days and rest days.

Zhou originated in Babylon as a time period. The world week system was formally established by the Roman emperor Constantine the Great on March 7th, 32 1 year.

China called it "Seven Obsidian" in ancient times. During the Xia, Shang and Zhou Dynasties in China, Seven Obsidian refers to seven main stars, such as the sun, the moon and the five major planets, which was an important part of astronomical astrology at that time. Later, it was borrowed as a time unit of seven days, so it was called "week".

Historical origin

Zhou originated in Babylon as a time period. The world-wide seven-day week system was first formulated by the Roman emperor Constantine the Great, who officially declared seven days as a week on March 7th, 32 1 year, and this system has been in use ever since. In China, when Christianity spread in China in the late Ming and early Qing Dynasties, Zhou gradually became known. After the use of the Gregorian calendar was stipulated in the Republic of China, the week gradually became popular.
