36 U.S.C. § 106 — Constitution Day and Citizenship Day

(a) Designation. This section names September 17 as "Constitution Day and Citizenship Day." (b) Purpose. The day marks the anniversary of the Constitution being formed and signed, on September 17, 1787. It also recognizes everyone who has become a U.S. citizen — whether by coming of age as a citizen or through naturalization. (c) Proclamation. Each year, the President may issue a proclamation. It can call on United States government officials to fly the flag of the United States on all government buildings for the day, and can invite the people of the United States to observe the day — in schools, churches, or other suitable places — with appropriate ceremonies. (d) State and Local Observances. State and local civil and educational authorities — of states, counties, cities, and towns — are urged to plan their own proper observances of the day, and to fully teach citizens about their responsibilities and opportunities as citizens of the United States and of the state and locality where they live.
