what was constitution day first called

Constitution Day was first called "Citizenship Day." It 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. Before the law was enacted in 2004, 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
