Held annually, Earth Hour inspires individuals, communities, and businesses to dedicate an hour to the Earth. It is marked by landmarks and businesses switching off non-essential lights from 8:30 PM to 9:30 PM, typically on the last Saturday of March, as a symbolic commitment to the planet. Originally launched in Sydney, Australia, in 2007, it began as a simple lights-off initiative.
