On October 8, 1970, Public Law 91-443 under the 91st Congress, JJR 26 was passed by both the House and Senate and was sent to President Richard Nixon for his signature. The joint resolution was signed into law by President Nixon on August 2, 1971.  President Nixon released his "National Clown Week By the President of the United States of America A Proclamation". Since then Governors and Mayors have had their own Clown week proclamation for their state or city.   Today the National Clown Week has grown to International Clown Week. 

And is celebrated all over the world
