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 EPA and landmark environmental laws. Today it means tree plantings, cleanups, climate strikes and policy pushes — the Paris Climate Agreement was deliberately signed on Earth Day 2016. Each year carries an official theme guiding global campaigns.
