Event Info

Lights-Out Hour DC is a voluntary event in which individual residents, building managers, and custodians of public monuments dim or extinguish non-essential indoor and outdoor lights for one hour beginning at 8:30pm on March 25, 2023.

Lights-Out Hour DC coincides with international “Earth Hour,” and your participation will draw attention to climate change and the harm that light pollution presents to human health and the environment.

Dozens of cities around the world have observed Earth Hour since 2007. Iconic structures such as the Golden Gate Bridge, the Empire State Building, and the Eiffel Tower have gone dark during Earth Hour.

Let us join with cities around the world in a gesture of solidarity by “switching off” for one hour. Please spread the word about Lights-Out Hour DC.

For further information or to volunteer, please contact the D.C. Chapter of the International Dark-Sky Association at [email protected] or through our Facebook page.
