Extended information:
The week in ancient China was called Qiyao. During the Xia, Shang and Zhou dynasties in China, Qiyao refers to the seven major stars including the sun, the moon, and the five planets. It was an important organizational component of the astronomical phenomena at that time. Later, it was borrowed and used as a time unit of seven days per week, so it was called a week. A week, also called a week, is a unit of time and is also the basis for formulating working days and rest days.
