Excuse me, what festival is August 15th?

Mid-Autumn Festival, also known as Moon Festival, Moonlight Birthday, Moon Festival, Autumn Festival, Mid-Autumn Festival, Moon Festival, Moon Festival and Reunion Festival, is a traditional folk festival in China. The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from the worship of the autumn moon in ancient times. At first, the festival of "Sacrificing the Moon" was held on the "Autumn Equinox" of the twenty-four solar terms in the Ganzhi calendar, and later it was moved to August 15th in the summer calendar (lunar calendar). In some places, the Mid-Autumn Festival is set on August 16 in the summer calendar. Since ancient times, Mid-Autumn Festival has had folk customs such as offering sacrifices to the moon, enjoying the moon, eating moon cakes, playing with lanterns, enjoying osmanthus and drinking osmanthus wine. It has been circulating for a long time.

The Mid-Autumn Festival originated in ancient times, popularized in the Han Dynasty, shaped in the early Tang Dynasty and prevailed after the Song Dynasty. Mid-Autumn Festival is a synthesis of autumn seasonal customs, most of which have ancient origins. The Mid-Autumn Festival is a colorful and precious cultural heritage. The full moon is a symbol of people's reunion, a sustenance for missing their hometown and relatives, and hopes for a bumper harvest and happiness.

Mid-Autumn Festival, Spring Festival, Tomb-Sweeping Day and Dragon Boat Festival are also called the four traditional festivals in China. Influenced by China culture, Mid-Autumn Festival is also a traditional festival for overseas Chinese in some countries in East and Southeast Asia, especially local Chinese.
