Earth Hour tonight -8:30pm to 9:30pm

What is Earth Hour?

WWF’s Earth Hour is a global annual event where hundreds of millions of people switch off their lights for one hour to show they care about our planet. It’s about people from across the globe coming together to create a symbolic and spectacular lights out display and asking for change.

It happens every year between 8.30 and 9.30pm, with switch offs starting in Samoa and finishing in Tahiti. It’s been growing every year, with more and more countries and people signing up – last year we hit an all-time record with 162 countries taking part!

How you spend the hour is up to you. You could have a dinner party with friends or loved ones by candlelight, practice your yoga skills or play board games with the family – if you’re lucky, you might even get to try a spot of stargazing!

It’s something so simple but with a big message – we want to protect the future of our planet. Will you join us?

A record 162 countries took part in Earth Hour 2014, showing a phenomenal amount of support from the UK, to Australia, Uruguay and Russia.

60 special Earth Hour pandas named by WWF-UK supporters were unleashed across the UK to help spread the message about Earth Hour. #Passthepanda selfies popped up all across social media and even celebrities like Stephen Fry, Eliza Doolittle and Jack Whitehall shared their photos.

On the day in 2014, dancing pandas took to the streets of London’s Southbank to celebrate Earth Hour and #passthepanda. In the evening we had an exclusive performance from Sophie Ellis Bextor and we live-streamed Big Ben’s switch off with the help ofDougie from McFly.

10 million people in the UK and 157 countries took part in one of the world’s greatest mass participation event.

What will you be doing tonight at 8:30pm to 9:30pm. Send us your photos or tell us what you did.
