Live countdown to Earth Day 2027
About Earth Day
Earth Day is the world’s largest environmental observance: tree plantings, cleanups, and climate education events held every April 22.
The story behind Earth Day
Earth Day was invented by a senator and organized by a student. Senator Gaylord Nelson, shaken by a 1969 oil spill off Santa Barbara, proposed teach-ins on the environment; 25-year-old Denis Hayes coordinated them — and on April 22, 1970, some 20 million Americans, a tenth of the population, took to streets, parks and lecture halls.
The date was chosen pragmatically: April 22 sat between spring break and final exams, maximizing student turnout. It worked so well that within months the US Environmental Protection Agency existed, and the Clean Air, Clean Water and Endangered Species Acts followed.
In 1990 the day went global, reaching 140 countries and paving the way for the 1992 UN Earth Summit. Today it is called the largest secular observance in the world — and the date is deliberately unchanged, a fixed point on the calendar for the planet.
