Each year, Earth Hour is celebrated on Saturday night near the equinox in March. This year, Earth Hour will be observed on Saturday, March 27th at 8:30 p.m., in every time zone across the world. Earth Hour is a promise to conserve energy. Millions will turn off their lights and pledge to protect our planet all year round. Will you and your family join in the celebration?
