The Mid-Autumn Festival in 2026 will fall on September 17th. This traditional Chinese holiday, also known as the Moon Festival, is celebrated on the 15th day of the eighth lunar month. The date varies each year because the lunar calendar is based on the phases of the moon, which are not synchronized with the Gregorian calendar used in the United States. In 2026, the lunar calendar aligns such that the Mid-Autumn Festival occurs on September 17th. This date is significant for the Chinese community in Pennsylvania, as it provides an opportunity for cultural celebration and family gatherings. The festival is characterized by moon观赏, mooncakes, and lanterns, and it holds great importance in Chinese culture, symbolizing reunion and prosperity.
