The 12 Days of Christmas is a traditional English Christmas carol that originated in the 18th century. The exact origins of the song are not entirely clear, but it is believed to have been written by a clergyman named Robert L. Mayhew as a way to teach children the 12 days of Christmas. The song quickly became a popular part of the Christmas season, with each verse representing one of the 12 days between Christmas and the Epiphany. The 12 Days of Christmas has been performed and enjoyed for generations and remains a beloved holiday song today.
