The 12 days of Christmas is a traditional English Christmas carol that dates back to the 18th century. The carol tells the story of a young man who is in love with a wealthy woman. On each of the 12 days leading up to Christmas, he sends her a gift that represents one of the 12 days of Christmas. The gifts range from partridges in pear trees to ladies dancing and lords a-leaping. The carol has become a beloved Christmas tradition, and the 12 days of Christmas are often celebrated with parties and other festive activities.
