Constitution Week begins Sept. 17^th with Citizenship Day and Constitution Day and is observed the week of Sept. 17 – 23. The Library of Congress official site describes these observances as being created to both commemorate the signing of the Constitution on Sept. 17, 1787, and “recognize all who, by coming of age or by naturalization, have become citizens.” During this time, the U.S. Citizenship and Immigration Services “encourages Americans to reflect on the rights and responsibilities of citizenship and what it means to be a U.S. citizen.”
