Ours stay up until 6th, that is when Xmas ends, not boxing day or even new year, though I fully understand that those who are working will probably take them down this weekend. I always looked forward to coming home to them after the first dreary return to work days in the new year, and I'm now keeping to that for my son who has to go out to work some days of the week. And, apart from a dustpan and brush to deal with a few crumbs, it's a holiday from housework as well and a thorough dust and hoover will be done after all the decorations have been taken down.
