Constitution Day, according to the Library of Congress, "is observed each year on September 17 to commemorate the signing of the Constitution on September 17, 1787, and “recognize all who, by coming of age or by naturalization, have become citizens.”"
The holiday has been observed in some form or another since 1940, when it was initially intended to celebrate new American citizens. Over the years, its date and form has changed somewhat, but the holiday is still all about being an American citizen—no matter how that happens.
