Earth Hour 2016

March 19, 2016 | 8:30-9:30 PM

Every year, hundreds of millions of people around the world switch off their lights for one designated hour to demonstrate a commitment to fighting climate change. During Earth Hour—which takes place March 19, 2016, at 8:30 p.m. local time—individuals, businesses, and world leaders join together in an iconic and unprecedented lights-out display.

WWF launched Earth Hour in 2007 in Sydney, Australia, drawing in more than 2 million participants. The event now engages more than 172 countries and territories and millions of people around the world.

Taking part in Earth Hour is easy

1. Turn off all non-essential lights at 8:30 p.m. your local time and let us know you are taking part. 
2. Celebrate your commitment to the planet with your friends, family, community, or at work. You could host a candlelight dinner party with friends or practice your yoga skills by moonlight. Here are more ideas you can do in the dark.
