New Year's Day (new year) is January 1 of the Gregorian calendar, also known as the Gregorian year, the new calendar year, and the solar calendar year, marking the arrival of the new year.
In fact, China's "New Year's Day" has always referred to "the first day of the first month", and the calculation method of "new month" was also very inconsistent before the time of Emperor Wu of the Han Dynasty. The summer calendar of the summer period takes spring and January as the first month, the Yin calendar of the Shang period takes winter December as the first month, and the weekly calendar of the Zhou period takes winter November as the first month. After Qin Shi Huang unified China, the winter October was the first month, that is, the first day of October was New Year's Day. From the time of Emperor Wu of the Han Dynasty, the spring month was stipulated 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.
In 1949, when the First Chinese Political Consultative Conference established the People's Republic of China, it also decided to adopt the common common common era chronology (that is, the solar calendar) in the world, with January 1 of the Gregorian calendar as New Year's Day. The first day of the first lunar month of the summer calendar coincided with the "spring" in the twenty-four solar terms, so the first day of the first month of the summer calendar was renamed "Spring Festival".
Legend has it that more than 4,000 years ago, when Yao was in power, he was diligent in government and was widely loved by the people, but because his son had no talent and was not a great instrument, he passed the position of the leader of the "tribal alliance" to Shun, who had both moral character and ability, and later Shun passed on the throne to Yu, who had made meritorious contributions to the flood. Later, people regarded the day when Emperor Shun sacrificed heaven and earth and the first emperor Yao after Yao's death as the beginning of the year, and called the first day of the first lunar month "New Year's Day". It is said that this is the origin of the ancient "New Year's Day".
