Winter holidays in Lithuania have roots in pre-Christian traditions but became associated with Christian dates. Key winter holidays include Christmas Eve celebrated on the longest night with a large supper and rituals after dark. Christmas is a three-day celebration of the return of the sun that involved religious rituals and social gatherings. New Year's Eve involved divination of the next year's harvest. Epiphany marks the end of Christmas celebrations and involves processions where people dressed as supernatural beings and the Three Kings visited homes bringing well-wishes.
