Microsoft will be helping out users who search with When users search for ‘when does the tree go up in Rockefeller Plaza‘ or something similar, the following excerpt will be pulled from Wikipedia.

The Rockefeller Center Christmas Tree is a large Christmas tree placed annually in Rockefeller Center in mid-town Manhattan in New York City. The tree is erected and lit in late November or early December.

Unfortunately, the information will not have the exact date as The so visitors will still need to check the Annual Ceremony section of the site.
