National Day of the Republic of China (Taiwan National Day)

The National Day of the Republic of China, also referred to as Double Ten Day, Double Tenth Day, or Taiwan National Day, is a public holiday on 10 October, now held annually in the Taiwan Area of the Republic of China (ROC).

It was also celebrated during the ROC rule in mainland China before 1949. The date continues to be observed by the subsequent People's Republic of China (PRC) as the Anniversary of the Xinhai Revolution but not as a public holiday. It commemorates the start of the Wuchang Uprising on 10 October 1911 which ultimately led to the collapse of the imperial Qing dynasty and establishment of the ROC on 1 January 1912.

Following the outcome of the Chinese Civil War, the ROC government lost control of mainland China to the Chinese Communist Party and retreated to the island of Taiwan in December 1949.

The National Day is mainly celebrated in ROC-controlled territories, but it is also celebrated by many overseas Chinese communities.
