Chinese Mid-Autumn Festival
The Mid-Autumn Festival (中秋節) is a harvest festival celebrated notably by the Chinese and Vietnamese people. In Korea, a similar celebration called “Chuseok” is observed, and in Japan “Tsukimi” is celebrated. The festival is held on the 15th day of the 8th month of the lunar calendar with a full moon at night, corresponding to mid September to early October of the Gregorian calendar.
Mooncakes, a rich pastry typically filled with sweet-bean or lotus-seed paste, are traditionally eaten during the festival. Read more on the Mid Autumn Festival Wikipedia page.
