The Qingming Festival or Ching Ming Festival, also known as Tomb-Sweeping Day in English, is a traditional Chinese festival observed by ethnic Chinese in mainland China, Hong Kong, Macau, Taiwan, Malaysia, Singapore, Cambodia, Indonesia, Philippines, Thailand, and Vietnam. A celebration of spring, it falls 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, 5 or 6 April in a given year. During Qingming, Chinese families visit the tombs of their ancestors to clean the gravesites and make ritual offerings to their ancestors. Offerings would typically include traditional food dishes and the burning of joss sticks and joss paper. The holiday recognizes the traditional reverence of one's ancestors in Chinese culture.

The traditional Chinese calendar is a lunisolar calendar, combining the solar, lunar, and other cycles for various social and agricultural purposes. More recently, in China and Chinese communities the Gregorian calendar has been adopted and adapted in various ways, and is generally the basis for standard civic purposes, though also incorporating traditional lunisolar holidays. Also, there are many types and subtypes of the Chinese calendar, partly reflecting developments in astronomical observation and horology, with over a millennium's worth of history. The major modern form is the Gregorian calendar-based official version of Mainland China, though diaspora versions are also notable in other regions of China and Chinese-influenced cultures; however, aspects of the traditional lunisolar calendar remain popular, including the association of the twelve animals of the Chinese Zodiac in relation to months and years.
