Earth Hour 2020 was held on March 28, from 8:30 pm to 9:30 pm.
About:
What is Earth Hour? Earth Hour is a global grassroots movement uniting people to take action on environmental issues and protect the planet.
Organized by: World Wide Fund for Nature (WWF).
Background: Earth Hour was started as a lights out event in Sydney, Australia in 2007.
When does Earth Hour take place? The annual Earth Hour lights out event is held worldwide toward the end of March to encourage individuals, households, communities and businesses to turn off their non-essential lights for one hour as a symbol for their commitment to the planet.
Why is Earth Hour the event held in late March? The second-to-last and last weekend of March is around the time of the Spring and Autumn equinoxes in the northern and southern hemispheres respectively, which allows for near coincidental sunset times in both hemispheres, thereby ensuring the greatest visual impact for a global ‘lights out’ event.
Earth Hour logo: Earlier it was 60 (60 symbolizes 60 minutes). But since 2011 it is 60+. Here + represents the commitment to go beyond the earth hour (i.e. switching off non – essential lights in day to day life).
