What Day off for Chuseok Holiday marks

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, Myanmar, Thailand, and Vietnam. A celebration of spring, it falls on the first day of the fifth solar term, also called Qingming, 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 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.
