Alas, I missed Christmas (and Advent?) in July, so this question isn’t as timely
Looking ahead, though. I want to have an Advent wreath in my dorm room, and I already know laypeople can bless them. However, I’ll likely be travelling back to campus on the first Sunday of Advent. So unless I bring my wreath with me, I’d miss the proper day to bless one. Is it permissible, then, to just bless it on the Monday instead?
