Yesterday, my children came home from Primary with a handout listing scriptures to read on each of the 12 days of Christmas, beginning December 14. This irritates me mightily. The 12 days of Christmas begin on Christmas Day, and extend until January 6, when the season of Epiphany begins. December 14-24 properly belong to the season of Advent.
A little knowledge of the Christian calendar would help Mormons understand the rest of the Christian world better, and would also help to center our lives around religiously meaningful markers of time, rather than American cultural markers largely designed to increase material consumption.
That is all. Thank you for your attention.
