The song is based on the Twelve Days of Christmas, but the "8 Days" in the title is a reference to Hanukkah, but the holiday is never mentioned in the song. Knowles stated during the "8 Days of Christmas" video premiere at 106 & Park in Fall 2001: "Actually we wrote the song two years ago, when we went in the studio to do some Christmas something. That's what started the idea of doing a Christmas album."
A video was filmed for "8 Days of Christmas" and was released in the winter of 2001. It was directed by Sanaa Hamri. All 3 members appear in Santa-like clothing at a toy store on a snowy day. Throughout the video the group shops for various gifts and in between cuts, Knowles rides on a carousel. At the end of the video, many children begin rushing into the toy store where the group gives out gifts.
