For one hour, the world goes dark. Landmarks from the Eiffel Tower to the Sydney Opera House fade into the night. It is a moment of unity, a quiet protest, and a loud statement.
If you are searching "How many days until Earth Hour?", you are joining millions of people across 190 countries ready to take a stand for our planet. What started as a simple lights-off event in Sydney has grown into one of the world's largest grassroots movements for the environment.
Our Live Earth Hour Countdown Tool above ensures you are ready to flip the switch at exactly 8:30 PM local time. But beyond the timer, this guide is your manifesto. We will explore the origins of the movement, the real impact of switching off, and how you can go beyond the hour to create lasting change.
When is Earth Hour 2026? (March 28, 2026)
Earth Hour is observed annually on the last Saturday of March.
⏰ The Golden Rule: 8:30 PM
Unlike global holidays that happen simultaneously, Earth Hour is a "rolling" event. It happens at 8:30 PM local time wherever you are in the world.
This creates a stunning visual wave of darkness traveling across the globe, time zone by time zone, symbolizing a united front against climate change and nature loss.
From Sydney to the World: A Brief History
The movement began down under.
2007: The World Wildlife Fund (WWF) Australia and partners launched the first Earth Hour in Sydney. On March 31, more than 2.2 million individuals and 2,000 businesses turned off their lights for one hour to take a stand against climate change.
2008: The idea went viral. Ideally timed near the equinox (when sunset times are similar in both hemispheres), 35 countries and 371 cities participated. The Golden Gate Bridge and the Colosseum went dark.
Today: It has evolved from a symbolic "lights off" event into a catalyst for positive environmental impact, driving major legislative changes and inspiring millions to act.
Does It Actually Work? The Numbers
Critics often ask if turning off lights for an hour really saves energy. While the energy saved is measurable, the real power of Earth Hour lies in awareness and policy change.
190+
Countries and territories officially participate every year.
410,000
Hours given to the planet in the recent "Biggest Hour for Earth" campaign.
4%
Average drop in electricity consumption during the hour in major cities.
Policy
The movement helped create a 3.5 million hectare marine-protected area in Argentina.
Your Countdown Strategy: How to Spend the Hour
So, the lights are off. Now what? Use our days until Earth Hour timer to plan a meaningful 60 minutes.
- Candlelit Dinner: Turn a sustainability pledge into a romantic evening or a fun family dinner. Use beeswax or soy candles (eco-friendly) instead of paraffin.
- Stargazing: With less light pollution in your immediate area, head to the backyard or a balcony. It is a rare chance to see the night sky a little clearer in urban areas.
- Unplug Completely: Don't just turn off the lights—turn off the screens. Disconnect from the digital world and reconnect with the people in the room. Play board games, tell stories, or just talk.
- Night Walk: Go for a walk in your neighborhood. Seeing other houses dark creates a powerful sense of community solidarity.
The "Biggest Hour for Earth"
In recent years, WWF has rebranded the event to encourage action beyond just switching off lights. They ask participants to "Give an Hour for Earth" by doing something positive for the planet.
Clean Up: Spend 60 minutes picking up trash in your local park or beach during the day.
Learn: Spend the hour watching a documentary about biodiversity, reading about climate solutions, or listening to an environmental podcast.
Plant: Spend the hour gardening, planting a tree, or setting up a bee-friendly window box.
