When did China begin to spend New Year's Day in Zhihu?

In modern times, New Year's Day refers to the first day of the first year of the year. Since the Gregorian calendar was introduced into China, the word New Year's Day has been dedicated to the New Year, and the traditional old calendar year is called the Spring Festival.

Before that, New Year's Day always refers to the first day of the Chinese New Year. Yuan means "early" and "beginning", but it means "day". New Year's Day is called "the first day" and is the first day of the year.

1On September 27th, 949, the first plenary session of the China People's Political Consultative Conference decided that "the people of China and the national calendar should adopt the AD calendar method", which is what we call the solar calendar. In order to distinguish between the two New Years, and in view of the fact that the "beginning of spring" in the 24 solar terms of the lunar calendar is just around the Lunar New Year, the first day of the first lunar month is changed to "Spring Festival" and the solar calendar is January.
