when do they take the christmas tree down in nyc

Well, that depends on the city and the individual. The official holiday season usually ends on New Year's Day, so most cities and individuals take down their decorations around that time. However, some people like to keep their decorations up a little longer for the sake of nostalgia and to brighten up the cold, dreary winter months. In New York City specifically, the Christmas tree at Rockefeller Center is typically taken down on January 12th, just after the New Year's Day celebrations.
