Commercially?? Christmas is not meant to be some celebration of out-buying the next guy to look good. If anything it is to give from your heart to show your love and appreciation.
Spiritually, Religiously Christmas is meant as a day of remembrance to remember and celebrate the fact that God chose to become a fleshly being and dwell amongst man to teach man and eventually offer Himself as a perfect Godly sacrifice for the sins of man.
Does Christmas start to early? Commercially definitely YES!
Spiritually it should be each day every day of the year.
