In New York City, the iconic Rockefeller Center Christmas tree is traditionally lit on the Friday after Thanksgiving. The lighting ceremony is a major event in the city, and the tree is a cherished symbol of the holiday season. The tree typically stays lit until early January, providing a festive atmosphere for the city during the holiday season. However, other Christmas trees in the city, such as those in homes, offices, and other public spaces, can be set up at any time leading up to Christmas, depending on personal preference.
