New Year's Day is the lunar month.

New Year's Day in Gregorian calendar is 1+0.

Most countries in the world usually call it "New Year". On new year's day, yuan is called "start", and the beginning of each number is called "yuan"; Dan means "heaven"; New Year's Day means "the first day". New Year's Day is also called "three yuan", that is, year yuan, month yuan and time yuan.

The word "New Year's Day" in the history of China first appeared in the Book of Jin. In the history of China, "New Year's Day" means "the first day of the first month". The calculation method of "the first month" was very inconsistent before the period of Emperor Wu of the Han Dynasty, and the date of New Year's Day in previous dynasties was also inconsistent. From the beginning of Emperor Wu of the Han Dynasty, January of the lunar calendar was defined as "the first month", and the first day of January was called New Year's Day, which was used until the end of the Qing Dynasty.

After the Revolution of 1911, it was decided to use the Gregorian calendar in the first year of the Republic of China (actually used as 19 12), and it was stipulated that the Gregorian calendar 65438+ 10/was called "New Year's Day", but it was not called "New Year's Day". 1949, People's Republic of China (PRC) took 65438+ 10 1 as New Year's Day, so New Year's Day is also called "solar year", "new calendar year" or "Gregorian year" in China.
