Earth Hour is a worldwide movement organized by the World Wildlife Fund (WWF). The event is held annually, encouraging the individuals, communities, and businesses to give an hour for Earth, and additionally marked by landmarks and businesses switching off non-essential electric lights, for one hour from 8:30 to 9:30 p.m., usually on the last Saturday of March, as a symbol of commitment to the planet.[1] It was started as a lights-off event in Sydney, Australia, in 2007.
Occasionally, in years when Holy Saturday falls on the last Saturday of March (as in 2024), Earth Hour is held a week earlier.
