Every year millions of people around the globe will switch off for Earth Hour to shine a light on the need for climate action.
Haarlem city is proud to take in Earth Hour each year, where people and businesses turn off their lights for one hour on the 25th of March. Earth Hour starts at 20:30.
Help spread the word, donate or organize an event to celebrate by visiting the Earth Hour Website.
You can also do something personal, like host a candle lit dinner for friends, have a glow in the dark party or anything your imagination allows!
Head on to the center of town to see the lights turned off this Saturday 25th March at 20:30.
