Chuseok, literally "Autumn eve", also known as hangawi, is a major harvest festival and a three-day holiday in both North and South Korea celebrated on the 15th day of the 8th month of the lunar calendar on the full moon. Like many other harvest festivals around the world, it is held around the autumn equinox, i.e. at the very end of summer or in early autumn. It is one of the biggest traditional holidays.
