Learn more about the annual Constitution Day.

What is Constitution Day?

On September 17, 1787, the Founding Fathers signed the United States Constitution, establishing the foundational framework of our federal government.

In 1952, Congress passed a joint resolution declaring September 17 as a day to commemorate the signing of the Constitution and to recognize individuals who had attained U.S. citizenship, calling it "National Citizenship Day." 

In 2004, the day was formally named "Constitution Day and Citizenship Day" by Public Law 108-447, the Consolidated Appropriations Act. This law requires educational institutions receiving federal funds to provide programming on the history of the American Constitution.

Each year, colleges, universities, and schools across the country honor this day with educational events that celebrate both the Constitution and those who have become American citizens.


The Constitution shapes our rights and freedoms—from free speech and due process to voting rights and checks on government power. Constitution Day invites us to reflect on how this living document impacts our daily lives and civic responsibilities.
