Great topic! First weekend of December for us. Harks back to a year when the kids where little won’t bore you with the story. But has stayed a tradition with us since even though it’s just us now. I wouldn’t stop putting the decs and a tree up because the kids aren’t around but each to their own. Definitely wouldn’t put up in November but to me in a world where stress and depression are becoming so prevalent, if putting your Christmas tree makes you happy then I don’t see why not!
I think traditionally the 12 days of Christmas is from Christmas Day until 6th Jan, could be wrong on that though!
