  • Clocks go forward one hour at 1am on Sunday morning
  • Earth Hour celebrated tonight between 8.30pm and 9.30pm
  • Switch off non-essential lights for Earth Hour

The clocks go forward tonight/tomorrow morning at 1am.

It will mean an hour less in bed but it does, of course, mean we can enjoy brighter evenings.

And with the start of British Summer Time (or Daylight Savings Time) also comes the annual celebration of Earth Hour.

Earth Hour is a worldwide grassroots movement uniting people to protect the planet, and is organised by WWF. Engaging a massive mainstream community on a broad range of environmental issues, Earth Hour was famously started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage more than 7,000 cities and towns worldwide, and the one-hour event continues to remain the key driver of the now larger movement.

Earth Hour 2015 will be held on Saturday, 28 March, between 8.30PM and 9.30PM. The event is held worldwide towards the end of March annually, encouraging individuals, communities households and businesses to turn off their non-essential lights for one hour as a symbol for their commitment to the planet.

Earth Hour aims to encourage an interconnected global community to share the opportunities and challenges of creating a sustainable world.

The first thing anyone can do to get involved is to turn off their lights tonight. But there is much, much more. Their full ambition is for people to take action beyond the hour. Whether it’s supporting a crowdfunding or crowdsourcing campaign on or getting involved in Earth Hour campaigns in their own country, or starting the movement in their own community. The vision is always to do more, so make the light switch the beginning of your journey.

The first Earth Hour event was on March 31 2007. WWF-Australia inspired Sydney-siders to show their support for climate change action. More than 2.2 million individuals and 2,000 businesses turned their lights out for one hour in the first Earth Hour event.

Earth Hour 2015 will mark the ninth year of the campaign.
