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 – this year we hit an all-time record with 172 countries and territories taking part!
Next year’s celebrations will be on Saturday 19 March 2016, 8.30-9.30pm.
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. If you took part this year, it’s not too late to let us know – just click the sign up button below.Sign up now!
