What website coordinates many global Earth Day events today?

Earthday.org coordinates many global Earth Day events today.

The site, operated by EARTHDAY.ORG, maintains a global event map where organizers can register cleanups, educational programs, rallies, tree-plantings, and other activities. Visitors can search the map by location to find nearby events. The organization says its map connects local efforts with the worldwide Earth Day movement.

Earth Day began in the United States on April 22, 1970, but it became an international campaign in later decades. EARTHDAY.ORG—formerly known as Earth Day Network—now promotes activities across countries and supports campaigns such as the Great Global Cleanup. The website is therefore a coordination hub, not merely an informational homepage.

A common mix-up is confusing Earth Day with World Environment Day. World Environment Day is associated with the United Nations and takes place on June 5; Earth Day is observed on April 22. Other environmental groups may list events, but earthday.org is the central platform referenced by this question.
