On a walk in the neighborhood I ran across an interesting juxtaposition of holiday decorations. This house is decorated for Christmas, waiting for the snow and the passing of the Thanksgiving holiday, while next door the orange of Halloween is still very much present.
Not Jack O'Lanterns, just pumpkins left over from Halloween sitting outside waiting to be replaced by Christmas decor.
I don't think anyone decorates their homes for Thanksgiving. I haven't seen any turkey statues or cranberry displays.
Thanksgiving was first declared by Abraham Lincoln in 1863, during the Civil War, and has been celebrated ever since - usually as the fourth Thursday in November.
