Constitution Day and Citizenship Day

Featured Content
Commemorating the formation and signing of the U.S. Constitution, and recognizing those who have become U.S. citizens

Constitution Day, celebrated on September 17th in the United States, is an annual celebration of one of the most significant documents in American history – the United States Constitution. This year, as we mark Constitution Day 2023, we reflect upon the enduring importance of this foundational document and the principles it upholds.

The date itself commemorates the signing of the Constitution at the end of the Constitutional Convention, held from May 25 to September 17, 1787. This historic document serves as a remarkable blueprint for a governed body, ensuring the protection of individual rights, the rule of law, and the preservation of the nation’s values. The Constitution establishes three branches – Legislative, Executive, and Judicial – along with a system of checks and balances ensuring no single branch would have too much power.

It wasn’t until 2004 that the holiday took on the full name it bears today. In 2004, a law was enacted renaming the holiday “Constitution Day and Citizenship Day,” (36 U.S.C. 106) requiring public schools and institutions to provide information on the history of the country’s Constitution.

Constitution Day celebrations take various forms across the country. Educational institutions often organize special programs and discussions about the Constitution’s history and contemporary relevance. It is a time for students to learn about the nation’s history and the importance of civic engagement.
