Constitution Day

September 17 is designated as Constitution Day and Citizenship Day to commemorate the signing of the U.S. Constitution in Philadelphia on September 17, 1787.

Constitution Day is an American federal observance that recognizes the ratification of the United States Constitution and those who have become U.S. citizens.

Every year, in honor of Constitution Day, the Caltech Store passes out pocket-sized U.S. Constitution booklets. Make sure to stop by and get your free copy.
