Constitution Day and Citizenship Day2026 · Date · History

36 U.S.C. §106 designates September 17 as Constitution Day and Citizenship Day and states that it commemorates the Constitution’s signing on September 17, 1787 and recognizes citizens. Public Law 108-447 added the combined Constitution Day title in 2004 and requires federally funded educational institutions to provide a Constitution program; current Department of Education guidance confirms the annual requirement.

About Constitution Day and Citizenship Day

In the United States, September 17 is designated by federal law as Constitution Day and Citizenship Day.

The date commemorates the signing of the Constitution on September 17, 1787 and also recognizes people who have become U.S. citizens by age or naturalization.

Why Constitution Day and Citizenship Day matters

The observance combines constitutional history with civic education and citizenship recognition.

Its legal wording should be described directly from statute without turning the page into partisan advocacy or individualized citizenship, immigration, or legal advice.

History of Constitution Day and Citizenship Day

The Constitution was signed in Philadelphia on September 17, 1787.

Federal law had designated September 17 as Citizenship Day before the current combined title was adopted.

Public Law 108-447 in 2004 amended 36 U.S.C. §106 to use the title Constitution Day and Citizenship Day.

The same 2004 law requires educational institutions receiving federal funds to hold an educational program on the Constitution for their students.

Current Department of Education guidance says the program is held on September 17, with a preceding or following week option when the date falls on a weekend or holiday.
