Constitution Day is observed each year on September 17, to commemorate the signing of The Constitution of the United States on September 17, 1787. As Citizenship Day (formerly observed on the third Sunday in May), it “recognizes all who, by coming of age or by naturalization, have become citizens.”
The final draft of The Constitution was signed by 39 delegates. The document was then sent to the states for ratification, and went into effect on June 21, 1788, when New Hampshire became the ninth state to ratify The Constitution.
