The annual Light the Lights celebration kicks off the daily holiday light and music show on the plaza and steps of Denver’s City and County Building. This year’s event is Friday, November 21, 2025. At approximately 5:15 pm, the giant switch will be flipped by Mayor Mike Johnston, illuminating the City and County Building in an overload of holiday cheer!

Because of the renovations to Civic Center Park, this year’s opening ceremony will be short and simple—about 15 minutes long—featuring remarks from Mayor Johnston and the first lighting of the season.
While there will be no amenities or programming beyond the ceremony, the event will be streamed live on Denver 8 TV and the City’s Facebook page so everyone can join the celebration from wherever they are.
Visitors who wish to see the lights in person can come down any evening during the holiday season to enjoy the nightly light and music show.
