Bah, Humbug!
Christmas Eve, remove on Boxing day
A year ago, a house around here won a national competition for the most grandiose Christmas display. Unquestionably, it was impressive. Lights, color, sound, continuously falling artificial snow, pine scent... the whole magilla. Every square foot of their yard was filled, and the entire acre rimmed with ground-to-treetop decorations forming a wall of sensory overload.
The house was in a cul-de-sac, which meant the traffic from an awed public driving past was so crushing that the unfortunate neighbors had to be parked in their own driveways by 4 pm or risk not getting home before midnight.
I asked the owner of the house how long it took to erect their Yuletide masterpiece. He said they started on Labor Day. That's too hardcore for me.
I absolutely love Christmas. It's the most wonderful time of the year, no question about it. But I also love autumn, Oktoberfest, Halloween, harvest festivals, Thanksgiving, etc. Why forgo those wonderful events just to shortcut to another one?
We get around to decorating about 10 days before Christmas, and we take stuff down on 6 January, aka the 12th day of Christmas.
Recommend to DD that she savor the other seasons (autumn, Thanksgiving, etc.) in their time, and don't rush to Christmas too early. Overall this means more time for celebrating!
