The equinoctial Earth Day is celebrated on the March equinox (around March 20) to mark the precise moment of astronomical mid-spring in the Northern Hemisphere, and of astronomical mid-autumn in the Southern Hemisphere. An equinox in astronomy is that moment in time (not a whole day) when the center of the Sun can be observed to be directly "above" the Earth's equator, occurring around March 20 and September 23 each year. In most cultures, the equinoxes and solstices are considered to start or separate the seasons.

Is a day early each year on which events are held worldwide to increase awareness and appreciation of the Earth's natural environment. Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 175 countries every year. In 2009, the United Nations designated April 22 International Mother Earth Day. Earth Day is planned for April 22 in all years at least through 2015.
