Chinese New Year, also known as the Spring Festival, is celebrated from the first day of the lunar new year until the 15th day. It is the most important celebration in the Chinese calendar. Traditions include cleaning houses to sweep away bad luck, decorating with lucky phrases, having large family meals, setting off fireworks at midnight, giving children red envelopes with money, and dragon dances. The festival concludes with the Lantern Festival on the 15th day where people hang lanterns and carry them in the moonlight.
