Well, the process of decorating New York City for Christmas begins as early as September, when the city's Department of Transportation begins planning the annual Winter's Eve at Lincoln Square celebration. During the event, which takes place on the first Monday in December, thousands of people gather in the Lincoln Square neighborhood to enjoy the city's official kickoff to the holiday season. There are performances by choirs and orchestras, a parade of marching bands, and the annual tree lighting ceremony at Lincoln Square Park.
