From the first chapter of Genesis, the Christian Bible, God created water and air on the first day, plants on the third day, the sun and the moon on the fourth day, fish, birds and other creatures on the fifth day, and livestock, insects, wild animals and people in charge of all this on the sixth day.

On the seventh rest day, human beings worship God to thank him. Since then, when people make calendars, they take seven days as a cycle and rest on the seventh day, but they must worship God. This is the origin of "Sunday".

The weekly system founded by Babylonians first spread to ancient countries such as Greece and Rome. On March 7th, 32 1 year, Emperor Constantine officially announced that all citizens' craftsmen would be put to death if they worked on the sacred Sun Day (church history), which was later called "Sunday" because Christians had to take Sunday as a religious ritual cycle to pay homage to God.

Sunday is also called Sunday. But Sunday came from Genesis, and later Christians called it Sunday. With the introduction of Christianity, the word "Sunday" was applied. Sunday, also known as Sunday, originated in the two river basins of Babylon. According to astronomy (several planets in the solar system), they calculated the dates of stars with a period of seven days.

Week is the date of the stars. Later, with the introduction of Islam into China, the word "Zhou" was used. China is the hometown of Obsidian. For example, Obsidian Day is Sunday, also known as Sunday, the first day of the week. And the Sabbath of the Bible is the seventh day-Saturday.
