The Chinese New Year, or Spring Festival as it's been called since the 20th century, remains the most important social and economic holiday in China. Originally tied to the lunar-solar Chinese calendar, the holiday was a time to honor household and heavenly deities as well as ancestors. It was also a time to bring family together for feasting. With the popular adoption in China of the Western calendar in 1912, the Chinese joined in celebrating January 1 as New Year's Day. China, however, continues to celebrate the traditional Chinese New Year, although in a shorter version with a new name–the Spring Festival. Significantly, younger generations of Chinese now observe the holiday in a very different manner from their ancestors. For some young people, the holiday has evolved from an opportunity to renew family ties to a chance for relaxation from work.
