About Earth Day
Earth Day falls on April 22, mobilizing more than a billion people in over 190 countries — the largest secular observance in the world. The countdown above tracks the days until the planet's biggest day of environmental action.
The first Earth Day in 1970 brought 20 million Americans into the streets and helped create the US Environmental Protection Agency and landmark environmental laws. Today it means tree plantings, cleanups, climate strikes and policy pushes — the Paris Climate Agreement was deliberately opened for signature on Earth Day 2016. Each year carries an official theme that guides campaigns from schools and businesses to city governments around the world.
Earth Day always falls on April 22, so the date is fixed and only the weekday shifts from year to year. That consistency makes it a natural anchor for classrooms, community groups and companies planning sustainability events well in advance. The countdown above shows exactly how many days, hours and minutes remain until the next Earth Day, recalculated in your timezone — add it to your own page to rally a cleanup, a planting or a pledge before the day arrives.
