One year we waited until about May to take it down. Mid January works for me. When you're tired of all the pie and ham and turkey leftovers, and the Christmas presents have all but migrated out of the living room, and everythings boxed up to go in the shed/garage/basement, you should have your tree down. Some people in my neighborhood were out taking their lights down on the 26th. Mid January is the time IMHO. What miffs me, is that the radio stations stop playing xmas music immediately at 12am on the 26th. They start on Halloween, and play nothing else, and since I still live with the folks, I listen to them all the time on the radio. By the week before Xmas, I have stopped hating the holiday and the rush and the constant onslaught of the hated music, and by Christmas Eve, I have decided that I actually enjoy Christmas, and then it's over! I shouldn't complain, I wash it all down on New Years Eve.
