Christmas decorations in New York can vary in length, but they usually stay up until the New Year's Eve. In New York City, the Rockefeller Center Christmas tree is lit on November 28th and remains up until January 9th. Many stores and businesses also display Christmas decorations during the holiday season. However, the city also has a tradition of taking down decorations quickly after the holiday, so you might only have until January 1st to enjoy the festive atmosphere in New York.
