Lantern Festival is the fifteenth day of the first lunar month.
Because the first month is the first month of the lunar calendar, the ancients called the night "dawn", so the fifteenth day of the first full moon in a year is called the Lantern Festival.
Introduction of Lantern Festival:
Lantern Festival is a traditional festival in China, which existed as early as 2,000 years ago in the Qin Dynasty. According to data and folklore, the fifteenth day of the first month was paid attention to in the Western Han Dynasty. On the first night of the first month of the first month, Emperor Wu of the Han Dynasty offered sacrifices to "Taiyi" (Taiyi: the God who rules everything in the universe) in Ganquan Palace, which was regarded by later generations as the forerunner of offering sacrifices to the gods on the fifteenth day of the first month.
Yuanxiao originally meant "the night of Shangyuan Festival", because the main activities of Shangyuan Festival on the fifteenth day of the first month were to eat glutinous rice balls and enjoy the moon at night, and later the name of this festival evolved into "Lantern Festival". On the night of Lantern Festival, the streets are decorated with lanterns and colorful decorations, and people enjoy lanterns, solve riddles on the lanterns and eat Lantern Festival, which pushes the celebration activities started on New Year's Eve to another climax and becomes a custom handed down from generation to generation. Yuanxiao was only called the fifteenth day of the first month, the first half of the first month or the full moon when the early festivals were formed, and it was called Yuanxiao or Yuanxiao after Sui. Influenced by Taoism in the early Tang Dynasty, it was also called Shangyuan, but it was only in the late Tang Dynasty that it was occasionally called Yuanxiao. But since the Song Dynasty, it has also been called Dengxi. In the Qing dynasty, it was also called the Lantern Festival.
