The iconic Rockefeller Center Christmas tree, located in the heart of New York City, is typically lit during the annual Christmas Tree Lighting Ceremony in late November. The date can vary from year to year, but it is usually around the third week of November. It's a grand affair with music, performances, and the lighting of the tree, which is always a breathtaking sight. The lighting of the tree marks the start of the holiday season in New York City and is a beloved tradition for many.
