The decorating phase of Christmas can vary in the US from the day of Thanksgiving to the day (or night) before Christmas. In most households, the custom of decoration is a personal matter and usually includes a tree and some stockings as the base of the decoration.
In most household, this phase is conducted generally on a weekend and includes saved ornaments for the tree, with some reaching back generations. This custom shows continuity and brings fond memories of the holiday by hanging the ornament on the current tree.
The custom of outside lights is different and is a fairly recent event. This activity can start as early as April for involved light shows, with the hanging of the lights starting as early as October.
Once again, the custom is personal to families so there is no definitive answer to when the majority of people in the US decorate their homes.
No most people decorate before that. Many people in the US decorate the day after Thanksgiving.
