Golden Gate Bridge Off for Earth Hour

Earth Hour 2015

March 28 at 8:30 to 9:30 p.m. Local Time

Earth Hour is the world’s largest celebration for our planet. During Earth Hour, hundreds of millions of people around the world turn off their lights for one hour to show their commitment to helping something we all have in common—the planet.

Earth Hour is a visual reminder that the world’s environmental issues don’t have to overwhelm us. Small things we do every day will make a better future and together we can make change happen. So whether you reflect under the stars or celebrate by candlelight, turn off your lights and show you’ll do your part to protect our planet.

We need your help to make our statement seen around the world the strongest it has ever been. Turn out your lights for one hour on Saturday, March 28 at 8:30 p.m. and show your commitment to a better future.
