The Twelve Days of Christmas is a traditional Christmas carol that originates from England. It's a cumulative song, meaning each verse builds on the previous one. The lyrics detail a series of increasingly extravagant gifts that are given to the singer over the span of twelve days, starting on Christmas Day. The gifts are typically associated with different aspects of the Christmas season and include things like partridges in pear trees, calling birds, French hens, golden rings, and more. The song is often sung as a fun way to celebrate the season and remember the story behind each gift.
