Thanksgiving is not the same day for us here in Canada.
As for what it too early? It's never too early for me. I'm terribly in love with the holiday. I was just saying on another thread that last year it was in August and I told my partner that I was done Christmas shopping, everything was wrapped, and I wanted to put up the tree. He said no so we didn't.... but I would have if I was alone.
Something about the lights, tree, decorations, and wrapped presents under the tree just makes me in such a great mood.
...but I'm weird like that.
