Sun Day
From Wikipedia, the free encyclopedia
Sun Day (May 3, 1978) was designated by United States President Jimmy Carter, specifically devoted to advocacy for solar power,[1] following a joint resolution by Congress, H.J.Res. 715 becoming Pub. L.Tooltip Public Law (United States) 95–253.[2] It was modeled on the highly successful Earth Day of April 22, 1970. It was the idea of Denis Hayes, who also coordinated Earth Day in 1970.[3] The date became an international event in 1994.[4]
