Although many people think the song counts down the days to Christmas, the 12 Days of Christmas are the days after Christmas that count down the days to Epiphany, the day the wise men appeared to bring gifts to the Baby Jesus.
Of course, the song is a folk song that really has little to do with the Bible story, Unless one believes the theory that when Christians were persecuted, the song was written with each idea representing something in the Bible, for example the partridge represents Christ, the two turtle doves represent the Old and New Testaments, and so on.
I've always loved the song and decided to find a few printables to share with you. What you'll do with them, well, I don't know. I think I'll just walk around singing for a few days, attend mass as much as possible, and appreciate that we can celebrate the Christmas season just a little longer.
