Constitution Day (or Citizenship Day), is an American federal observance that recognizes the adoption of the United States Constitution and those who have become U.S. citizens. It is normally observed on September 17, the day in 1787 that delegates to the Constitutional Convention signed the document in Philadelphia. When Constitution Day falls on a weekend or on another holiday, schools and other institutions observe the holiday on an adjacent weekday. The law establishing the present holiday was created in 2004 with the passage of an amendment by Senator Robert Byrd to the Omnibus spending bill of 2004. Before this law was enacted, the holiday was known as "Citizenship Day" and celebrated on the third Sunday in May. In addition to renaming the holiday "Constitution Day and Citizenship Day," the act mandates that all publicly funded educational institutions, and all federal agencies, provide educational programming on the history of the American Constitution on that day. In May 2005, the United States Department of Education announced the enactment of this law and that it would apply to any school receiving federal funds of any kind. History Origins Iowa schools first recognized Constitution Day in 1911. In 1917, the Sons of the American Revolution formed a committee to promote Constitution Day. The committee included members such as Calvin Coolidge, John D. Rockefeller, and General John Pershing. I am an American Day This day was inspired by Arthur Pine, the head of a publicity-public relations firm in New York City bearing his name. At the New York World's Fair, the writers of a new song called "I am an American" brought their manuscript to the attention of Arthur Pine who handled publicity for the band leader, Gray Gordon, and a music publisher. Arthur Pine had the song introduced on NBC, Mutual, and ABC by the orchestra leader, arranged for an "I am an American Day" at the 1939 New York World's Fair, and had a local New York newspaper tie-in with "I am an American Day" in the city. The promotion proved so successful that a newspaper chain promoted "I am an American Day" on a nationwide basis and had President Roosevelt name it as an official day. In 1939, William Randolph Hearst advocated, through his chain of daily newspapers, the creation of a holiday to celebrate citizenship. In 1940, Congress designated the third Sunday in May as "I am an American Day." In
