Epiphany as well, with no real pressure. But much past the 15th, and you start to look really lame.
So I usually pack up the first weekend AFTER the 6th. Like one of the PPs, I don't put my decorations or tree up until late, so I'm in no hurry to get it down.
Of course, if the tree is disintegrating, it goes down sooner. This year's tree is STILL drinking really well (we bought it from a corner stand on Dec. 23, which is late, so I'm really surprised), so we kinda wish we could leave it up. But I think we'll be taking it down on Sunday or Saturday.
