Growing up, my parents would graciously decline the birthday party invitations that we received when they were scheduled for a Sunday. Many of these parties involved going to places, such a pizza parlors, that most Mormons would eschew on Sundays. But others were merely gatherings at homes. Still, they got the same treatment. I also remember Halloweens that fell on a Sunday. Some members would not let their children participate and sponsored special Saturday Trick-or-Treats. But my parents, it turns out, didn’t have an objection to trick-or-treating on Sunday. More recently, I’ve been to wards where church activities were not allowed to be held on the Friday and Saturday before fast Sunday. In other wards, this seems fine.
