You have from at 10 a.m. Thursday until 9:59 a.m. Monday to enter your name to win one of 3,000 tickets for seats or one of 14,000 standing-room tickets.

The lighting ceremony will be held on Dec. 1 on the Ellipse.

Performers for this year’s event haven’t been announced yet, but the National Park Foundation promises “an all star line-up.”

Last year’s event included performances by B.B. King and Maroon 5. Do we dare dream of a Justin Bieber Christmas miracle?
