Don’t be left in the dark about Earth Hour this year

Celebrate Earth Hour 2026 with The Weather Network.

Lights out! On Saturday, March 28 at 8:30 p.m. local time, 180+ countries and territories will dim their lights to honour Earth Hour as a way to raise awareness, and demand action on biodiversity loss and climate change.

For years, households around the world have unplugged and switched off their lights at home for 60 minutes as a symbol of commitment to our planet in need.

Here are a few ways you can take part in the initiative this year.

YOUR EARTH HOUR CHECKLIST

Be prepared. Charge your devices beforehand so that you can unplug all unnecessary electronics. Don’t forget to light candles and/or have a flashlight handy so that you’re not completely in the dark.
