Don’t forget that tonight, December 3, is the official lighting of the Rockefeller Center Tree in New York City. Most of us will not be in New York City, but we can watch it on NBC from 8-9 pm tonight, with the tree lighting at 8:55 pm EST. If you live in New York, you’re lucky enough to view it on TV from 7-9 pm EST. Happy decorating! And, for a history lesson on Christmas trees, check out History.com for information on the Rockefeller Center Tree and all Christmas trees and the Christmas season. Did you know that the tree dates the Depression Era days? Or that the tree typically has 25,000 lights on it? Here are some Rockefeller Center tree pictures from a visit in December 2004 (most likely taken my friend Ellen).
