Earth Hour 2027 · 20th anniversaryEarth Hour is just the beginning.
An hour can change everything. Start by switching off. Then turn that hour into a new habit, a gift, a conversation or an action for the planet you love.
For 20 years, people have gone dark together. This year, let’s use that powerful hour to begin something brighter.

One hour. Then another.
What if Earth Hour changed more than an hour?
Your life can change through the habits you repeat. The same is true for our planet. Earth Hour can be the moment we switch off, reconnect, and choose what we’ll do differently next.
Start with one hour of action. Build from there.

Turn the hour into something visible
Light up the movement.
A virtual candle is more than a donation. It becomes a visible part of Earth Hour. Light one for yourself, or give your organisation its own piece of the night.
For individuals
Light your candle
Make a $25 gift and add your name and message to Australia’s virtual Earth Hour candle wall.

For business
Own a constellation.
Instead of buying a corporate “box”, your organisation creates a branded constellation of lights within the Earth Hour candle wall. Every employee, customer or partner you invite can add another light.

The business mechanic
Your people build it with you.
A business starts the constellation with a corporate gift. It then receives a unique link to share internally and externally. Each person who joins adds a light carrying their first name or an optional message.
The goal: fill your constellation before Earth Hour.
1

Go dark together
Australia’s icons are in.
Landmarks across the country are switching off. Their darkness is a visible reminder of what collective action can look like.
Earth Hour is more than switching off lights—it's a powerful moment to stand up for our planet. Nature is under threat, but together, we can make a difference.
Join us to Switch off for it's 20th year and donate to help restore ecosystems, protect wildlife, and fight climate change. Every dollar support WWF's critical work—creating lasting impact for the future of our planet.
Join million across the world and #switchoff for the Biggest Hour for Earth. Saturday 28 March at 8:30 PM (local time)
Helping Koalas
Koalas are in crisis
Did you know koalas were officially listed as endangered in parts of Australia in 2022? Australia has the highest rate of deforestation in the developed world, destroying critial koala habitat and pushing their populations into decline. Without urgent action, their numbers will continue to fall. Your donation can help plant trees, protect habitats and give koalas a fighting chance. Donate today to help protect the future of one of Australia's most beloved animals.
Dinner in the Dark: On Saturday 28 March, celebrate Earth Hour by hosting a candlelit feast with friends and family, savoring the experience without distractions.
