Earth Hour is a global environmental movement that began in Sydney in 2007. It is usually held in March from 8:30 pm to 9:30 pm local time, when people, businesses and landmarks switch off non-essential lights or give an hour for the planet through environmental action.

During Earth Hour, people are encouraged to switch off non-essential lights for one hour or take another positive action for the planet. Landmarks, businesses, councils, schools and households may also participate.
Many people switch off non-essential lights between 8:30 pm and 9:30 pm local time as a symbol of environmental awareness.
Earth Hour can also be used for practical environmental actions, such as reducing waste, planning energy changes or joining local activities.
Families, schools and workplaces can use Earth Hour to start conversations about climate, biodiversity, energy, waste and sustainability.
Yes. Earth Hour began in Sydney in 2007 before growing into a global movement. The first event focused on switching off lights as a simple public symbol of concern about climate and the environment.
Earth Hour began as a Sydney-based lights-off event and later expanded internationally.
Earth Hour is now recognised in many countries, with households, landmarks, cities, communities and organisations taking part.
The switch-off is symbolic. The bigger value comes from ongoing action to reduce energy waste, protect nature and support sustainability.
Content angle: This page can rank for “what time is Earth Hour in Australia”, “when is Earth Hour”, “did Earth Hour start in Sydney” and school/community activity searches.
Earth Hour is easy to adapt for schools, workplaces, councils, families and community groups. The best activities connect the one-hour symbol to practical environmental habits.
Safety note: Do not turn off lights, equipment or systems needed for safety, accessibility, security, medical care, food safety or business-critical operations.
