What does Sunday mean?

Sunday is a marketing strategy of hotel marketing and a way to attract more customers. The Arabic numeral 8 looks like the sun, so Sunday is the code name of Sunday. Because of the particularity of Sunday, many shops will use it as their store name, which is not only easy to remember, but also eye-catching. For example, there is a famous experience sharing website called "Sunday", and a movie released on 20 17 is also called "Sunday", as well as cafes and billiards rooms.

In addition, many people will use the Eight Dynasties to refer to things that don't exist. For example, meeting on the eighth day means never meeting again, or looking for it on the eighth day means never finding it again.

The origin of a week

Zhou originated in Babylon and was formally established on March 7, 32 1 year. Week, also called week, is a unit of time, which is the basis for making working days and rest days. In ancient China, Zhou was called "Seven Obsidian", referring to seven main stars, such as the sun, the moon and the five planets, which was an important part of astronomical astrology at that time.

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.

China's seven obsidians did not begin as a unit of time. In the west, the ancient Babylonians first used seven days as a week. Later, the Jews spread it to ancient Egypt and from ancient Egypt to Rome. After the 3rd century AD, it spread widely to European countries.
