The story behind the day
Lunar New Year opens the first month of the Chinese calendar, on its first day. In China it is called the Spring Festival; Koreans keep it as Seollal and Vietnamese as Tết. It closes one year and opens the next: households clean, families gather for a late dinner on the eve, ancestors are honoured, and children receive red envelopes. The season runs until the Lantern Festival on the fifteenth day. Chinese folk religion and Confucian ideas of filial duty both shape the rites for ancestors.[1–11]
Origins

Chinese folk tradition explains the noise and colour of the season with the story of Nian, a fierce creature said to have preyed on villages on the final night of the lunar year. Firecrackers are lit to drive demons off, and the Smithsonian notes that fireworks were used to scare off evil spirits during the festival. Alongside the legend sits the older business of ritual: at the turning of the year, offerings go to the gods and to the ancestors. The legend is a popular explanation, and the ancestral offerings are the practice it grew around.[13–15]
What it marks
The festival marks the end of the old year and the start of the new. Confucian thought frames the honouring of ancestors as a way of fulfilling filial responsibilities, while folk belief holds that ancestors are the dead whom descendants feed, and that the dead who go unvenerated may become wandering ghosts. Both views give the family table and the family grave a weight beyond sentiment, and many people travel long distances to be home for the turn of the year.[9–11, 16]
How it came to be
The lunar year opens with the first new moon of its first month. After the founding of the Republic of China in 1912 its government adopted the Gregorian calendar for public use. Sources differ on when the lunar New Year came to be called the Spring Festival: a Columbia University guide ties the name to that reform, while a Wake Forest museum page dates the renaming to after 1949. In Korea, the Joseon dynasty built its social order on Confucian ritual. Ancestral rites were counted among four cardinal family rites, and Zhu Xi's Family Rituals was the manual from which Koreans took the rules of ancestor worship.[1, 17–18]
How it is kept

Beforehand people tidy their houses, lay in supplies and cook. On the eve of the new year families share a dinner and keep vigil late into the night; paired guardian prints are pasted at the main entrance, and elders give children red envelopes of money. Lion dances are a favourite of the season, and troupes may visit houses and shops to bring good luck. The celebration runs for about two weeks and ends on the fifteenth day with the Lantern Festival.[3–6, 19–20]
Across traditions

In Korea the day is Seollal. Families hold charye, a memorial service for ancestors, and tteokguk, sliced rice-cake soup, is a seasonal dish. Younger people then perform sebae, a deep bow to their elders. Vietnamese keep the new year as Tết. The festival is also widely celebrated wherever there is a large overseas Chinese population, and in the United States it is often known as Chinese New Year.[2, 7–8, 12, 21–22]
