How did the song ‘Twelve Days of Christmas’ start?

The first known publication of the carol was in the English children’s book “Mirth Without Mischief,” published in 1780.

Historians speculate that “the Christmas carol started out as a ‘memory-and-forfeit’ game in 1800s England,” per Good Housekeeping.

A memory-and-forfeit game is where one child starts the song, then each child builds upon the song and must repeat the past lyrics.

The popular version of the song we know was composed by Frederic Austin in 1909.

Like Andy Bernard aptly points out when he tries to gift his office crush the gifts from the carol on “The Office,” “Is it my fault the first eight days is basically 30 birds?”

Historians also theorize that “during a time when Christians were punished for worshiping openly,” the song served as a means to honor Jesus Christ and their religion with symbolism, according to Metro UK.
