WASHINGTON, D.C. (CNN) -- With the flip of a switch, the holiday season is officially under way at the White House.

On Thursday, December 6th, the first family counted down the seconds before the National Christmas Tree lit up on the White House lawn.

The 28-foot Colorado blue spruce is decorated with bright green lights and stars.

The National Park Service transplanted the tree just a couple of months ago after the old tree died.

The event was the 90th annual lighting of the National Christmas Tree.
