Earth Day is April 22nd of each year
Earth Day brief history:
Earth Day, celebrated April 22, is a day designed to inspire awareness and appreciation for the Earth’s environment. It is held annually during both spring in the northern hemisphere and autumn in the southern hemisphere. It was founded by U.S. Senator Gaylord Nelson as an environmental teach-in in 1970 and is celebrated in many countries every year.
The United Nations celebrates an Earth Day each year on the March equinox, a tradition which was founded by peace activist John McConnell in 1969
