The origin of New Year's Day?

People call 1 day in the solar calendar every year "New Year's Day". Why?

It turns out that in Chinese, "yuan" is the beginning, that is, the first; "Dan" means a day or morning. Together, these two words mean the first day of the New Year. But this is not fixed from the beginning.

In the calendar, people are used to calling the 1 period of the earth around the sun 1 year. However, because the earth's orbit around the sun has no fixed starting point and ending point, the starting point and ending point of a year are artificially stipulated, which leads to the inconsistency of various calendars. According to legend, the word "New Year's Day" comes from Zhuan Xu, one of the earliest emperors in China. He defined the first month of the lunar calendar as "Yuan" and the first day as "Dan". Later, some dynasties changed the date of New Year's Day, but in principle, the first day of each year is still regarded as New Year's Day. For example, the Xia Dynasty regarded the first day of the first month as New Year's Day, but the Shang Dynasty regarded it as New Year's Day. The Zhou Dynasty was 1 1, and the Qin Dynasty was 1. It was not until Emperor Wu of the Western Han Dynasty that the great historian Sima Qian and others reformulated the calendar, stipulating that the first day of the first month of the first month of each year was New Year's Day, and it has not changed since then.

19 1 1 After the success of the Revolution of 1911, it was decided to adopt the international Gregorian calendar, so the New Year's Day of the lunar calendar was changed to "Spring Festival" and 1 day of the Gregorian calendar was called New Year's Day. When New China was founded, the "AD Chronology Law" was officially used, and the annual Gregorian calendar 1 was designated as New Year's Day.

At present, most countries in the world take 65438+ 10 1 as New Year's Day, because most of them adopt the international Gregorian calendar. However, some countries and nationalities have different New Year's Day dates because of their local calendar traditions, religious beliefs, customs and seasonal climate, which makes the world more colorful and ethnic.
