DC, or District of Columbia, is the capital of the United States of America. As such, it is a bustling city with a strong government presence and many iconic landmarks and attractions. While there are certainly some areas of DC that may get into the holiday spirit and decorate for Christmas, the city as a whole does not have a specific timeline for holiday decorations. In general, you can expect to see some holiday cheer starting in late November or early December, with the city's main Christmas tree being illuminated in early December.
