As volunteers for Earth Hour 2020, we’ve been asked just about every question under the sun.

So we’ve put together some answers to shine a light on some of your most commonly asked questions - so you won’t be left in the dark.

1. What time is Earth Hour?
8.30pm (your local time) wherever you are in the world 8:30pm is the time to make the #SwitchforNature!



2. When is Earth Hour?
Saturday 27 March 2021



3. How long does Earth Hour go for?
Earth Hour goes for one hour - 60 minutes! From 8.30pm - 9.30pm - your local time.



4. So what is Earth Hour?
It is a symbolic lights-out event. It symbolises the growing global pursuit of a better, sustainable future for all.



5. What does the 60 in the Earth Hour logo mean?
Earth Hour - 1 Hour - 60 minutes!



6. What do I do for an hour while my lights are off?
In light of the COVID-19, we’ve decided to celebrate Earth Hour 2021 a little differently.
We're asking people to make the #SwitchforNature this Saturday 27 March.



7. What's the point of Earth Hour?
Earth Hour is more than just switching off your lights for 60 minutes. It’s not designed to save electricity, Earth Hour is a symbolic action taken by individuals, businesses and communities to inspire more action on climate change and to help protect the planet.
Earth Hour motivates people to look beyond the hour and has become a major catalyst for positive environmental impact.

Earth Hour inspires individuals and organisations worldwide to take action for the environment and drives major legislative changes by harnessing the power of the crowd.

It’s a time when the world’s population comes together to make the #SwitchforNature.



8. Does Earth Hour actually make an impact on energy use?
Earth Hour is not a carbon reduction exercise or an energy event - it is a symbolic action.



9. Will Earth Hour cause a power surge?
It’s extremely unlikely - after 10 years of switching off the lights for Earth Hour we’ve concluded it’s extremely unlikely that people will be switching their lights on and off simultaneously.



10. How many people participated in Earth Hour 2020?
Earth Hour 2020 was a huge success with more than 7,000 cities and 180 countries and territories participating to show their commitment to a healthy planet. 1 in 4 Australians choose to #SwitchOff their lights.

Will you be taking part this year? Sign up here.



11. How does switching off our lights help climate change?
Switching off for Earth Hour is a symbol of a broader commitment towards the planet and helps to spark conversations for change.
Australians' concerns and attitudes to the environment have shifted over the past few years, especially following the bushfire crisis of 2019-20.

By ‘switching off’, people are showing they will not stand to lose any more of Australia’s biodiversity.

And this year - every sign up to Earth Hour means you've decided to make the #SwitchforNature.
