Earth Day is an annual holiday, celebrated on April 22, on which events are held worldwide to demonstrate support for environmental protection.
In 1969 at a UNESCO Conference in San Francisco, the date proposed for Earth Day was March 21, 1970, the first day of spring in the northern hemisphere. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970.
Nelson chose the date in order to maximize participation on college campuses for what he conceived as an “environmental teach-in”. He determined the week of April 19–25 was the best bet as it did not fall during exams or spring breaks and was late enough in spring to have decent weather.
You would think a senator from Wisconsin would know that April is not late enough to have ‘decent’ weather, especially since it is snowing very heavily on this Earth Day in Wisconsin.
