The Qingming Festival (traitional Chinese: 清明節; simplified Chinese: 清明节; pinyin: Qīngmíngjié, Vietnamese language: Tết Thanh Minh), meaning Clear and Bright Festival, is a traditional Chinese festival on the 104th day after the winter solstice (or the 15th day from the Spring Equinox), usually occurring around April 5 of the Gregorian calendar (see Chinese calendar). Every leap year, Qing Ming is on April 4. Astronomically, it is also a solar term (See Qingming). In solar terms, the Qingming festival is on the 1st day of the 5th solar term, which is also named Qingming. Its name denotes a time for people to go outside and enjoy the greenery of springtime (踏青 Tàqīng, "treading on the greenery"), and also to tend to the graves of departed ones. It is an official public holiday in the People's Republic of China, Taiwan, Hong Kong and Macau. Prior to 2008, the holiday was not official in the People's Republic of China since the Communist Party of China classified it as superstition. It was officially celebrated as a public holiday for the first time on April 4, 2008.
