There are 12 days of Christmas in the traditional Christmas carol. Each day, a different aspect of the Christmas season is celebrated and included in the song, starting with the first day of Christmas on December 25th and ending with the twelfth day of Christmas on January 5th. Each day is associated with a different gift or celebration, such as the partridge in a pear tree on the first day, two turtle doves on the second day, and so on.
