The origin of New Year's Day can be traced back to Zhuanxu, one of the three prehistoric emperors and five emperors. According to legend, Zhuanxu "took the first month of Mengxia as the yuan", which means that the first day of the first lunar month every year must be "New Year's Day" or "Yuanzheng". This legend has a history of more than 5000 years. Subsequently, different dynasties had varying opinions on the specific date of New Year's Day. The Yin Shang Dynasty established the first day of the twelfth lunar month as New Year's Day, the Zhou Dynasty designated the first day of the eleventh lunar month as New Year's Day, and the Qin Dynasty established the first day of the tenth lunar month as New Year's Day. In the first year of the Taichu reign of Emperor Wu of Han (104 BC), the famous historian Sima Qian pioneered the "Taichu calendar", which takes the first day of the first lunar month as New Year's Day. This method returns to the original provisions of the "Xia Xiaozheng" (the earliest surviving calendar in China that records agriculture), and is therefore also known as the "Xia calendar". This regulation spans a long historical time and space and continued until the Xinhai Revolution.
Sun Yat sen designated January 1st of the Gregorian calendar as New Year's Day for the first time
In 1912, the Provisional Government of the Republic of China was established. Mr. Sun Yat sen established the first day of the first lunar month as the Spring Festival, and the first day of the first lunar month in the Gregorian calendar (Gregorian calendar) as the New Year's Day, also known as the New Year, in order to follow the lunar calendar. In this sense, New Year's Day is a product and symbol of the evolution of modern and contemporary society in China. In September 1949, the first plenary session of the Chinese People's Political Consultative Conference, which was held on the eve of the founding of the People's Republic of China, passed a resolution to adopt the "AD chronology method", which legally designated January 1st of the Gregorian calendar as New Year's Day and the first day of the first lunar month as the Spring Festival. At this point, New Year's Day has officially become a statutory holiday for all ethnic groups in China.
