When is it to early to decorate for Christmas

So when is it technically alright to start decorating for Christmas?  Well if you have been in stores lately you will notice that most have all ready decorated for the Holiday.  Every time I enter in the stores I get it itch more and more to start now.  I recently have been reminising through old photos from last year of my home.  Most of the people I have asked start in December.  I start in November normally,  the week of Thanksgiving.  Here are some pictures of what I do for the holidays.
