So, when would you put up the tree?

Monday morning I went out and looked at trees at Hobby Lobby. They had very little in the range of "not enormously tall and expensive."

So, I got my tree at Wal-Mart. I had looked at the various ones on display and matched up boxes and prices to trees, but there was one stack at the end with some kind of species of tree I didn't know-- a Black Fir. You know how they name the artificial trees after some kind of real tree that they're supposed to resemble, right?

Turns out that there is no Black Fir. There are fir trees, and this one...happens to come in the color black.

I couldn't resist. I now own a black Christmas tree. It's cheap and plastic and only 5' tall, but it's mine and I picked it out.

I am planning on asking the kid if she wants to put up the tree on my birthday (which is Sunday) or on Black Friday, as a tradition. We'll have a little chat about calendars and moving holidays and discuss how Thanksgiving is on the 4th Thursday, and thus Black Friday is on the Friday after the 4th Thursday, and see if she can deduce for herself whether my birthday can fall after Black Friday or not. (For those of you not willing to fiddle about with paper and pencil, Black Friday can fall on the 23rd through the 29th inclusive, so my birthday can fall ON it, but not AFTER it.)

This is the kind of wicked math puzzle my uncle used to set me, and I loved it.

I know some folks prefer to put up the tree later, like the 1st or even the 24th; what would you do?
