China has 7 legal festivals in a year, on which all Chinese people will be on vacation. They are New Year’s Day, Chinese New Year (Spring Festival), Qingming Festival, May Day, Dragon Boat Festival, Mid-Autumn Festival and National Day. Four of these are three-day holidays. There are two week-long national holidays in China: Chinese New Year or Spring Festival, in February, and National Day holiday, which is the first week of October.
A unique feature of Chinese holidays is that weekends, which are usually days off for office workers, are worked if there is a public holiday that week. For example if Monday to Wednesday was a public holiday then the weekend before would be worked, so the statutory holiday is effectively only one day.
