EARTH HOUR – Last Saturday in March

Earth Hour - Last Saturday in March
(Last Updated On: May 4, 2022)


Every year on the last Saturday in March, Earth Hour encourages individuals, communities, and businesses to turn off their non-essential lights. Participants turn off their lights for one hour from 8:30 to 9:30 p.m. to show commitment to the planet.

There are many people throughout the world who are concerned about our planet. And for good reason. According to some scientists, human civilization could deteriorate by 2050. This is largely due to the fact that the earth is getting warmer. Our planet’s temperature has increased by 2° F. in the last century.

Some believe that the planet’s temperature could increase by 5.4° F. by the year 2050. This is referred to as global warming, which is caused by an increase in greenhouse gases. When the earth is too hot, ice sheets and glaciers disappear, droughts kill trees in the Amazon rain forests, and humans suffer from frequent heatwaves. Warmer temperatures, along with floods, wildfires, and other natural disasters have the potential to cause ecosystems to collapse.

In order to prevent all of this from happening, we need to be proactive now. One of the best ways to do this is to decrease the emission of greenhouse gases. You can do your part by using less heat and air conditioning, using less gas, buying energy-efficient products, using less hot water and electricity, and planting a tree.


The best way to participate is to simply switch off any lights that run on electricity from 8:30 to 9:30 p.m. in your time zone. You can also connect online with an event in your country. Go to TikTok and participate in the #DanceForThePlanet challenge, as well as the #FlipTheSwitch challenge. You can also tune in to Spotify and check out a curated playlist of nature-inspired songs.

One more way to participate is to sign the “Voice for the Planet” petition. This petition lets world leaders know you care about nature and demand action to protect the planet. Also, be sure to spread awareness for this day sharing #EarthHour on social media.


The World Wide Fund for Nature (WWF), along with several partners, held its first lights-out event in 2007. The event was held in Sydney, Australia. Since then, Earth Hour has become one of the largest grassroots movements for the environment in the world. Today, more than 8 million participants in over 180 countries and territories turn off their lights to show their commitment to our planet.
