1. Traditional Xi customs: In traditional Chinese Xi customs, Chinese New Year's Eve is the last day of the year, and people will carry out activities such as cleaning, sticking Spring Festival couplets, and keeping the New Year on this day to welcome the arrival of the new year. The Spring Festival is the first day of the new year, and people will celebrate by greeting the New Year, setting off firecrackers, and eating Chinese New Year's Eve dinner. Therefore, there is a difference in time between Chinese New Year's Eve and Spring Festival.
2. Statutory holiday arrangement: According to China's statutory holiday arrangement, the Spring Festival holiday usually starts on Chinese New Year's Eve and lasts until the seventh or eighth day of the first lunar month. That said, Chinese New Year's Eve itself is part of the Spring Festival holiday.
3. Working day adjustment: In some places, due to the needs of work and life, the government will adjust Chinese New Year's Eve to a working day so that people can work normally on Chinese New Year's Eve and then take a holiday during the Spring Festival. In this case, although Chinese New Year's Eve is no longer a rest day, the Spring Festival holiday still includes the day of Chinese New Year's Eve.
In general, Chinese New Year's Eve is not a Spring Festival holiday, mainly because of the difference in time between the two and the difference in traditional Xi customs and statutory holiday arrangements.
