We always got a tree on my sisters birthday. December 14th
Until about ten years ago, we always had a real tree and put it up in mid-December. In recent years, we've used an artificial tree and put it up shortly after Thanksgiving.
We always get a real tree so about two weeks before X-mas works well.
My mother never put up a tree until about the end of the second week of December, and as a kid I was more than ready by then...
Usually right after Thanksgiving, but this year I bought a new tree and I put it up the other day. But we won't turn it on until mid-December.
It seems pretty early to put it up in November. I put mine up in early to mid December.
Or 1st December.
The perfect time is about December 1.
1973 was the last time I did a Christmas tree.
