I don't know how to put it into words but I believe it has something to do with the memmory wipe thing. Maybe everyone has to be indoors or not in contact with eachother once the new day starts (that's midnight) in order for the memmories to not return. Or maybe the brainwash is renewed at that point of the day. I also think that TSoR and Rebecca broke that rule and that's how they regained the memmories of their relationship.
