The National Day of the People's Republic of China, also known as National Day, National Day, China National Day, or National Day Golden Week, is a public holiday in the People's Republic of China aimed at celebrating National Day. It falls on October 1st every year. According to Article 2 of the State Council's "National Holidays and Commemorative Days Holiday Measures", the National Day holiday lasts for 3 days each year, on October 1st, 2nd, and 3rd.

On October 1, 1949, the Central People's Government of the People's Republic of China was established; On December 2nd, the Fourth Meeting of the Central People's Government Committee accepted the proposal of the National Committee of the Chinese People's Political Consultative Conference and passed the "Resolution on the National Day of the People's Republic of China", deciding to designate October 1st every year as the National Day of the People's Republic of China. After the founding of the People's Republic of China, the form of celebrating National Day has undergone several changes. From 1950 to 1959, large-scale celebrations were held every year, accompanied by military parades. From 1960 to 1970, grand rallies and mass parades were held annually in front of Tiananmen Square, but no military parades were held. From 1971 to 1983, it was celebrated annually through large-scale park activities and other forms, without any mass parades. In 1984, a military parade and mass celebration parade were held again. After 1985, National Day was mostly celebrated in other forms, without military parades or mass celebrations. Only in 1999, 2009, and 2019, military parades and mass celebrations were held again.

National Day is a characteristic of the country, which emerged with the establishment of the People's Republic of China and became particularly important. It has become a symbol of an independent country, reflecting China's national and political system. National Day is a new and universal holiday form that carries the function of reflecting the cohesion of China and the nation. At the same time, the large-scale celebration activities on National Day are a concrete manifestation of the government's mobilization and appeal. Displaying strength, enhancing national confidence, reflecting cohesion, and exerting appeal are the three basic characteristics of the National Day celebration.
