It's basically your right to put up your Christmas tree whenever you want. If you want it up in June, then go for it. Personally, I wait until mid to late December, but that's me. I am not too into Christmas. So, you do you.

I don't relish the thought of Christmas as I was born on Christmas eve and I am 95 next Christmas. Still trying to make video games. Have to use the screen magnifier to see anything.... but my friends are impressed.
