The "first day of the first month" in the current lunar calendar is historically known as Yuanshuo, Yuantian, Xinyuan, New Year's Day, Zhengri, Yuanchen, Xinzheng, etc. The name "Spring Festival", which is now celebrated on the first day of the first month of the lunar calendar, was not used in ancient times (generally known as New Year and New Year's Day in ancient times) and was created by the government of the Republic of China. The concept of "Spring Festival" was gradually raised during the Republic of China. During the period of the Republic of China, the Gregorian calendar was introduced, and the lunar calendar became the standard for farming. In 1914, the government of the Republic of China mentioned in the document submitted by the Ministry of Internal Affairs that "it is proposed to set the New Year's Day of the lunar calendar as the Spring Festival". Therefore, the Spring Festival has gradually spread.
