China's official public holiday calendar centres on a small number of statutory holidays, but these are expanded into extended breaks through weekend work-day swaps arranged by the State Council. National Day on October 1st creates the Golden Week, a seven-day holiday that is the longest annual break and triggers the world's largest human migration. Labour Day in early May provides another extended break. The most culturally significant celebration, Chinese New Year (Spring Festival), follows the lunar calendar and is not represented in this fixed-date list.
