The origin of New Year's Day (abbreviation)

New Year's Day, called "New Year" in most countries in the world, is the first day of the Gregorian New Year. Yuan, meaning "first"; Dan means "day"; New Year's Day means "the first day". The word "New Year's Day" first appeared in the Book of Jin: "It is actually the spring of New Year's Day when the emperor was transferred to the first month."

In ancient China, the first day of the twelfth lunar month and October were regarded as New Year's Day. The first day of the twelfth lunar month and the first day of October are 1 in the lunar calendar and 1 in the solar calendar in the Republic of China. 1949, People's Republic of China (PRC) took 65438+ 10/0/as New Year's Day, so New Year's Day is also called "Gregorian calendar year" in China.

It is said that New Year's Day began in Zhuan Xu, one of the three emperors and five emperors, with a history of more than 5,000 years.

New Year's Day in China always refers to the first day of the first month of the summer calendar (lunar calendar and lunar calendar). The calculation method of the first day of the first month was also very inconsistent before the period of Emperor Wu of the Han Dynasty. Therefore, the New Year's Day of the past dynasties is not consistent.

Meng Xiyue (1 month) is the first month of the Xia calendar, the twelfth month of the Shang lunar calendar (1February) and the winter month of the week calendar (1 1 month). After Qin Shihuang unified China, Yangchun month (October) was the first month, that is, the first day of October was New Year's Day.

Before Emperor Wu of the Han Dynasty, New Year's Day was also inconsistent because of the different calendars in previous dynasties. In the seventh year of Yuanfeng (BC 104), Emperor Wu ordered the calendar to be changed, taking Meng Yue (the first month of the summer calendar) as the beginning of the year, and the first day in Meng Yue was called New Year's Day, which was used until the end of the Qing Dynasty.
