The Mid-Autumn Festival (Moon Festival, Lantern Festival, Moon Cake Festival) is a popular East Asian celebration of abundance and togetherness, dating back over 3,000 years to China's Zhou Dynasty.

The Mid-Autumn Festival falls on August 15th of the Chinese lunar calendar (usually around mid- or late-September). This is the ideal time, when the moon is at its fullest and brightest, to celebrate the summer's harvest. The traditional food of this festival is the mooncake.

The festival is one of the two most important holidays in the Chinese calendar (the other being the Chinese Lunar New Year). The celebrations include eating moon cakes outside under the moon, carrying brightly lit lanterns, shops selling mooncakes, often display pictures of Chang'e (嫦娥, Cháng'é) floating to the moon, which is a familiar legend to most Chinese citizens.
