Twelve. According to the song "The Twelve Days of Christmas," the first day of Christmas is celebrated on December 25th, and each subsequent day is celebrated until the twelfth day of Christmas on January 5th. During these twelve days, gifts are given to represent the gifts that the Magi brought to baby Jesus, symbolizing the gifts of faith, hope, and love. Each day has its own specific gift, such as seven swans a-swimming or nine ladies dancing.
