Lights out for Earth Hour

Typography

Turn off your lights at 8:30 p.m. March 30 for an hour to express solidarity with environmental conservation efforts around the world. Earth Hour was started as a lights-off event in Sydney, Australia, in 2007. Since then, it has grown to include events in more than 180 countries and territories worldwide. People who participate often host candlelit dinners, go stargazing, throw Earth Hour parties or simply switch off their lights for an hour. Learn more by following the hashtag #Connect2Earth.
