The History of Constitution Day
The U.S. Constitution was signed by the Framers on September 17, 1787. In commemoration of that historic day, Congress sought fit to declare September 17th to be "Constitution Day and Citizenship Day" (see Consolidated Appropriations Act, 2005, Public Law 108-447, 118 Stat. 2809, 3344-45 (Section 111), excerpted here). In order to implement this new holiday, Congress requires all educational institutions receiving federal funding to hold an "educational program pertaining to the United States Constitution" (70 Fed. Reg. 29727 (May 24, 2005)).On Constitution Day:
