Over the years, humankind has increased the amount of light shining into the skies all night long, which has brought with it intrusive and harmful environmental and human impact. Believe it or not, natural darkness plays an essential role within our ecosystem, from promoting healthy plant growth and wildlife to enhancing our own health, sleep and enjoyment of the beauty of our night skies.

In an effort to combat light pollution, Fairfax County Park Authority invites residents to participate in Lights Out Fairfax and International Dark Sky Week.

Lights Out Fairfax - March 23, 2024, 8:30-9:30 p.m.

As our region has expanded, excessive light pollution has dimmed the night sky, impacting both our environment and our connection to the natural world. On March 23 from 8:30 to 9:30 p.m., residents are encouraged to join the initiative by turning off outdoor lights for one hour. By enlisting family, friends and neighbors, we can collectively embrace the darkness and rediscover the beauty of the stars. Once the light goes out, be sure to allow up to 15 minutes for your eyes to adjust, revealing the stellar spectacle that lies above.

International Dark Sky Week - April 2-8

Following Lights Out Fairfax, Fairfax County Park Authority will continue its commitment to dark sky conservation by participating in International Dark Sky Week from April 2 to 8. This weeklong event aims to raise awareness about the importance of preserving our dark skies and the detrimental effects of light pollution on human health, safety and the environment.
