When is Earth Day every year?

Earth Day (World Earth? Day) is April 22nd every year.

Development of Earth Day;

At first, Earth Day was chosen in the spring equinox. This day has the same length of day and night in any corner of the world, and the sun can shine at the South Pole and the North Pole at the same time, which represents the equality of the world and also symbolizes that human beings should put aside disputes and differences and live in harmony. Traditionally, many countries have the tradition of celebrating the vernal equinox and solar terms. In the early days, the United Nations also held Earth Day at the spring equinox every year.

The significance of Earth Day:

1970 "Earth Day" on April 22nd was the first large-scale mass environmental protection movement in human history.

As the beginning of modern human environmental protection movement, it promoted the establishment of environmental laws and regulations in western countries. For example, the United States has successively introduced the Clean Air Law, the Clean Water Law and the Endangered Animals Protection Law; Earth Day in 1970 also contributed to the establishment of the National Environmental Protection Agency of the United States, and to a certain extent contributed to the convening of the first United Nations Conference on the Human Environment in Stockholm in 1972, which effectively promoted the development of environmental protection in the world. 1973 The establishment of the United Nations Environment Programme, the establishment of Greenpeace, an international environmental organization, and the inaction of zf institutions and organizations on environmental protection in the world were the earliest large-scale mass environmental protection movements in the world, which catalyzed the development of modern human environmental protection movements and promoted the development of environmental protection legislation in various countries, and directly gave birth to the first United Nations Conference on the Human Environment in 1972. Dennis hayes, the organizer of the 1970 event, is also known as the "Father of Earth Day".

The success of this campaign makes it a practice to organize environmental protection activities on April 22nd every year. In the United States, the name of Earth Day has also moved from the vernal equinox to April 22nd, and the theme of Earth Day has also turned to environmental protection.
