September 17: Holidays, Historical Events, Famous Birthdays & Zodiac Sign
September 17 is Constitution Day and Citizenship Day — the day in 1787 when 39 delegates signed the document that would become the supreme law of the United States.
About September 17
September 17 anchors American civic identity: it was on this autumn day in Philadelphia that the Constitutional Convention concluded its work and the signed parchment headed to the states for ratification. Today, schools and communities mark Constitution Day and Citizenship Day with readings, naturalization ceremonies, and reflections on the rights and responsibilities the framers debated.
Beyond Philadelphia's State House, the date carries a striking range of milestones. In 1787 the same signing occurred; in 1849 Harriet Tubman reached freedom in Pennsylvania, beginning a legend of courage on the Underground Railroad. Fast-forward to 1976, when NASA unveiled the first space shuttle, Enterprise, signaling a new era of reusable flight.
The day also celebrates simpler pleasures — apple dumplings, warm queso, and the humble Monte Cristo sandwich. And globally, World Patient Safety Day reminds us that care and vigilance matter as much in hospitals as they do in constitutions.
