When do you put up a Christmas tree?

Basically the title! When do you put up a Christmas tree if you do? We have a tradition where we put up a big tree the day after Thanksgiving (none of us have EVER decorated before Thanksgiving) but I'm thinking of putting a small tree up in my bed room today(Nov 13) or in a few days lol bc I'm getting into the Spirit. Aside from all the rambling I wanna know when everyone else puts theirs up!? 

Usually early or mid November, before Thanksgiving at least. I do a woodland critter theme for my tree so in a way it's still fitting for fall.
