Earth Hour and why celebrate it at 8:30 PM?

Earth Hour is an international event that calls on households and businesses to switch off the lights and other electrical equipment in their homes for 1 hour. The event takes place every year at the end of March, on the weekend on which DST starts.

DST abbreviation means Daylight Saving Time. The idea behind summertime is set in place by the government as that one could cut back on (electric) lighting.

What, When and Why Earth Hour?

Every year, at 8:30 pm on the last Saturday of March, millions of people across the world show their support for our planet, raising awareness of nature loss and climate change – the two biggest threats facing our one home. Join millions of people around the world and switch off your lights in support of nature and our planet on Saturday, 26 March 2022 at 8:30 PM.

This is all started by the WWF organization (World Wildlife Fund) and its partners as a symbolic lights-out event. That happened in Sydney in 2007. Earth Hour is now one of the world’s largest grassroots movements for the environment. And is now held every year on the last Saturday of March, Earth Hour engages millions of people in more than 190 countries and territories, switching off their lights to show support for our planet.
