There are currently seven official public holidays in mainland China. Each year's holidays are announced about three weeks before the start of the year by the General Office of the State Council. A notable feature of mainland Chinese holidays is that weekends are usually swapped with the weekdays next to the actual holiday to create a longer holiday period. History Festivals in China have been around since the Qin dynasty around 221–206 BC. During the more prosperous Tang dynasty from AD 618–907, festivals involved less sacrifice and mystery to more entertainment. Culminating to the modern era Between the 1920s until around the 1970s, the Chinese began observing two sets of holidays, which were the traditional and what became "official", celebrating the accomplishments of the communist regime. There was then a major reform in 2008, abolishing the Labour Day Golden Week and adding three traditional Chinese holidays (Qingming Festival, Duanwu Festival, and Mid-Autumn Festival).

The week-long holidays on May (Labor) Day and National Day began in 2000, as a measure to increase and encourage holiday spending. The resulting seven-day or eight-day (if Mid-Autumn Festival is near National Day) holidays are called "Golden Weeks" (), and have become peak seasons for travel and tourism. In 2008, the Labor Day holiday was shortened to three days to reduce travel rushes to just twice a year, and instead, three traditional Chinese holidays were added. Generally, if there is a three-day or four-day (if Mid-Autumn Festival is near National Day) holiday, the government will declare it to be a seven-day or eight-day holiday. However, citizens are required to work during a nearby weekend. Businesses and schools would then treat the
