1, the origin of international practice:
According to Genesis, God created the world from Monday to Saturday and rested on Sundays, so Judaism and Christianity worship on Sundays.
They are called "Sunday" on this day, and a week is called "week" of seven days. Things like worshipping God are urgent, so put them on the first day of the week, so Sunday is the first day of the week.
In addition, semantically speaking, Sunday means Sunday. For people in all celestial bodies, the sun is the largest. This day is of course the most important day of the week, and we should worship God with nature.
2, the difference between China practice and international practice:
Although western countries and most countries/regions regard Sunday as the first day of the week, countries do not follow this practice. First of all, all documents, dictionaries and dictionaries in the country will be called Saturday and Sunday.
It is said that Sunday is the end of the week, not the beginning. Secondly, in the official documents, laws and regulations of the government, the weekend is written on Saturday and Sunday. We can see that Saturday is followed by Sunday, so in China, Monday is the first day of the week.

Historical origin:
Zhou originated in Babylon as a time period. At present, the system of seven days a week, which is widely practiced all over the world, was first formulated by the Roman emperor Constantine the Great. On March 7th, 32 1 year, he officially announced a seven-day week, 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.
Zhou is called the Seven Obsidian in China. During the Xia, Shang and Zhou Dynasties in China, Seven Obsidian refers to the seven main stars, such as the sun, the moon and the five planets, which was an important part of astronomical astrology at that time. 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. Both Islam and Christianity have weekly religious worship activities, so in many dialects, "worship" gradually has the meaning of "week".
The origin of the week should be the cycle connected with the moon, because seven days is about a quarter of the moon's week.
In ancient China, the ancients regarded the five planets of Sun, Moon, Jin Mu, Fire, Water and Earth as seven nights, which also made them the Seven Wonders. In the Preface of Biography of the Liang Dynasty by Fan Ning in the Eastern Jin Dynasty, there are seven records of "interference" among prostitutes.
