Earth Hour

Saturday, March 22 at 8:30 p.m. local time

Every year and everywhere, at 8:30 pm on a Saturday in late March, millions of people across the world join in raising awareness of the nature crises facing our planet.

It’s not just a symbol of support — it’s a catalyst for urgent change because Earth Hour is about more than 60 minutes. It’s a movement for our future.

Our planet is in crisis, but there is still time to keep biodiversity loss and climate change from reaching catastrophic levels.

To reverse nature loss by 2030, every hour is important. Spending 60 minutes doing something positive for the planet can turn into thousands and millions of hours of action and awareness.

On Saturday, March 22 at 8:30 pm local time, join millions of people around the world in making a difference during the Biggest Hour for Earth.

It’s time to make nature matter. This Earth Hour, take small actions, inspire big change – and give an hour for Earth.

Take part: Give an hour for Earth

How can you help us create the Biggest Hour for Earth?

Find 60 minutes to do something — anything — positive for our planet.

Not sure what to do? Check out these ideas:

  • Speak up for endangered Southern Resident killer whales. There are only 73 of these whales left, and they can’t wait for Parliament to return. Click here to send a letter to your local MP urging them to demand Cabinet issue an Emergency Order to protect them before it’s too late. 
  • Dream up your action plan for creating wildlife habitat at home or in your community. Sign up for a free re:grow account to learn how you can help support bees, birds and other wildlife by growing native plants. 
  • Register for the WWF Climb for Nature. This year, you can reach new heights for yourself and wildlife by participating in Toronto (April 5-6), Vancouver (May 10) or anywhere in Canada (April – June).

Every one of us has the power to make a positive impact on our planet – join us!
