The date of Earth Day
Earth Day is fixed on April 22, so only the weekday changes from year to year. It is not a federal or state holiday, and offices, banks and schools are open. In 2028 Earth Day is on Saturday, April 22, 2028.
The first Earth Day in 1970
Senator Gaylord Nelson of Wisconsin proposed a national teach-in on the environment, and the first Earth Day was held on April 22, 1970. An estimated 20 million Americans took part, with Denis Hayes as national coordinator. Nelson picked a date between spring break and final exams to draw students. The same year the Environmental Protection Agency was created, and the Clean Air Act was strengthened, followed by the Clean Water Act in 1972 and the Endangered Species Act in 1973.
Earth Day goes global
Earth Day went international in 1990, when about 200 million people in 141 countries took part. In 2009 the UN General Assembly named April 22 International Mother Earth Day. The Paris Agreement on climate change was opened for signature at the United Nations on Earth Day, April 22, 2016. See also National Arbor Day, the tree-planting day held later in April.
Who named Earth Day
The name "Earth Day" is often credited to the advertising writer Julian Koenig, who suggested it for the 1970 event. Representative Pete McCloskey, a Republican from California, was the Congressional co-chair with Senator Nelson, and the day drew support from both parties. President Bill Clinton awarded Nelson the Presidential Medal of Freedom in 1995 for his role.
Earth Day on the March equinox
A different Earth Day also exists. The peace activist John McConnell proposed an Earth Day on the March equinox in 1969, and San Francisco held the first such celebration on March 21, 1970. The United Nations still marks the equinox with a ceremony at its New York headquarters. April 22 is the date used in the United States and by most organizations.
Earth Day today
The Earth Day Network, the nonprofit group that Denis Hayes helped to found, coordinates events in more than 190 countries. Typical activities include clean-ups of parks and shores, tree plantings, community cycling days and school lessons, and many cities hold festivals and farmers markets around the date.
