Korean New Year (Korean: Seollal; hangul: 설날 or 구정, hanja: 舊正) is the first day of the lunar Korean calendar. It is the most important of the traditional Korean holidays. It consists of a period of celebrations, starting on New Year's Day. This is the day of the second new moon after the winter solstice, unless there is an intercalary eleventh or twelfth month in the lead-up to the New Year. In such a case, the New Year falls on the day of the third new moon after the solstice. (The next time this occurs is in 2033.)
