National Day, also known as Double Ten Day, is observed in Taiwan every October 10. This holiday commemorates the Wuchang Uprising of 1911, which initiated the Xinhai Revolution and led to the establishment of the Republic of China. Celebrations typically begin with a flag-raising ceremony in front of the Presidential Building, where the public sings the national anthem. The official events may include a military parade, followed by traditional festivities that showcase Taiwanese and Chinese culture. The President of Taiwan addresses the nation before a fireworks display. The scale of the celebrations can vary based on the political and social context, as seen in 2009 when government-sponsored festivities were canceled due to Typhoon Morakot. National Day is exclusively celebrated in Taiwan and is not recognized in mainland China.
