What is Earth Hour?

WWF’s Earth Hour is the world’s biggest movement to protect our planet.


Every year hundreds of millions of people around the world take part in Earth Hour. For 60 minutes people in more than 7,000 cities in over 190 countries switch off their lights as a symbolic gesture of solidarity to show they care about our planet and its future.


Earth Hour isn't just about switching off your lights. Our aim is to spark global conversations on the impacts of climate change and inspire positive action to protect our natural world. By working together we can help shape a bright future for us all.


This year, Earth Hour is at 8:30pm local time Saturday 25 March. We're inviting all Australians to sign up to take #TimeOutForNature and join the global community of millions supporting stronger action on climate change


Getting involved is easy! You could:

- Sign up to switch off this Earth Hour
- Take #TimeOutForNature and reflect on the incredible benefits nature provides us 

- Sign up to host a fundraiser this Earth Hour


If you're representing a group, look to our dedicated pages to find out how you can take part. We have resources to help individuals, schools, businesses and communities make the most of Earth Hour.


Are you ready to join the movement and take #TimeOutForNature?

Earth Hour: Over 10 Years of Impact

Did you know Earth Hour was started right here in Sydney in 2007?


Since then, Earth Hour has become a global movement for change and in 2017 we were proud to celebrate 10 years of Earth Hour. 


Take a look at the impact Earth Hour has made on climate change action all over the world during the last decade.


Our actions today can change our tomorrow.
