Switch off your power for an hour. Give an Hour for Earth. 28th March, 8.30pm local time,
Since our beginnings in 2007, Earth Hour has been known for the symbolic “lights off” in support of our planet. Over the years, we’ve stepped things up, breathed new life into our movement and mission to create the Biggest Hour for Earth.
In 2026, we’ll mark our 20th anniversary, celebrating two decades of collective action and storytelling from communities around the world.
