master post here, still taking prompts!01: how soon is too soon for Christmas decorations in a) shops and b) people's houses / gardens, and do you care?Shops: No sooner than a month before Christmas. I know that they want to sell As Much As Possible Zomg, but really the whole trend of "it's September, here, have some Christmas stuff next to the Halloween stuff" drives me batshit. And that's for having a section of Christmas stuff -- with an exception made if necessary for places that keep holiday items in stock year-round, though I don't know whether those exist.
Christmasifying stores and playing obnoxious pop carols over the sound system ought, in a proper world, never to happen; but since it does, two weeks before at the very least. And I feel so, so sorry for retail workers that have to put up with that shit during all of their working hours (and without going into a frothing rage and hacking the loudspeakers to pieces).
Houses and gardens: Depends on what. Lights along the roof edge, you can get away with a lot earlier. Actual holiday stuff? Not before December. I get a little less frothy about personal homes than about stores, but it is utterly, utterly wrong to have it up before December.
In an ideal world, of course, there would be a societally acceptable boundary between religious Christmas (celebrating the birth of Jesus, and only really relevant to Christian religions) and secular Christmas (bright lights and warm drinks and presents and eggnog -- and, at least in the Northern hemisphere, snow). A separation, even, that extends to being a completely different date. Maybe secular Christmas, which needs a different name, could be on the solstice, or could cohabitate the New Year boundary.
In which case items and decorations relating to religious Christmas, which would hopefully be less pushed upon the masses in general, would start with Advent and end with Epiphany; and items and decorations relating to secular not-Christmas could maybe get away with starting mid-November because cold, and could run through December and then ... stop.
Or maybe continue in lieu of Valentine's Day stupidities.
