Constitution Day in Taiwan Date in the current year: December 25, 2024

The first Constitution of the Republic of China was adopted in 1912 after the Xinhai Revolution that overthrew the Qing dynasty. It was a provisional constitution framed by the Provisional Government led by Sun Yat-sen. Another provisional constitution was promulgated in 1931 by the nationalist government led by Chiang Kai-shek.

The current Constitution of Taiwan was adopted in 1946 in the aftermath of the Second Sino-Japanese War. Chiang Kai-shek was pressured into adopting a democratic constitution that ended one-party rule of the Kuomintang. The National Assembly adopted the Constitution on December 25, 1946. The document came into effect one year later, on December 25, 1947.

December 25 was officially designated as Constitution Day in 1963. It is not a national holiday, so many businesses remain open. Over the years, Taiwan's Constitution Day has lost its significance. It coincides with the Christmas day, and many people celebrate Christmas instead.
