Earth Hour began as a symbolic lights-out event in Sydney in 2007, and is now one of the world’s largest grassroots movements for the environment. Held every year on the last Saturday of March, Earth Hour engages millions of people in more than 180 countries and territories, switching off their lights to show support for our planet.

This year, Earth Hour falls on Saturday 27 March, running from 8:30pm. Everyone is welcome and encouraged to take part, with this year providing the first “virtual lights-off”. Switch off your lights for an hour on Saturday, March 27, 2021 at 8:30 pm your local time.
