It's always Earth Day here 24/7 365.
From Wikipedia:
Earth Day is an annual event, celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network[1] and celebrated in more than 193 countries each year.[2]
On Earth Day 2016, the landmark Paris Agreement is scheduled to be signed by the United States, China, and some 120 other countries.[3][4] This signing satisfies a key requirement for the entry into force of the historic draft climate protection treaty adopted by consensus of the 195 nations present at the 2015 United Nations Climate Change Conference in Paris.
In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be celebrated on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-infirst held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom award in recognition of his work.[5] While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations.[6][7] Numerous communities celebrate Earth Week, an entire week of activities focused on the environmental issues that the world faces.
