The Qingming or Ching Ming Festival, also known as Tomb-Sweeping Day in English, is a traditional Chinese festival on the first day of the fifth solar term of the traditional Chinese lunisolar calendar. This makes it the 15th day after the Spring Equinox, either 4 or 5 April in a given year. Other common translations include Chinese Memorial Day and Ancestors’ Day.
Qingming has been regularly observed as a statutory public holiday in China. In Taiwan, the public holiday is now always observed on 5 April to honor the death of Chiang Kai-shek on that day in 1975. It became a public holiday in mainland China in 2008.
