Summary
More than 230 years ago—on September 17, 1787—the Constitutional Convention wrapped up its work in Philadelphia, producing the U.S. Constitution, creating a new framework of government built on compromise, balance, and enduring principles.
September 17 marks the 230th anniversary of the U.S. Constitution’s signing in 1787. More than a historic milestone, it is a living framework that shapes the freedoms and responsibilities we live with every day.
At Sonoran Desert Institute (SDI), we recognize Constitution Day as both a celebration and a reminder. For our students, alumni, and faculty — many of whom have served in the military — this document is not just a symbol but a commitment they have defended and upheld.
Why the Constitution Still Connects to Daily Life
-
Free Expression (First Amendment): Protects your right to share ideas, whether in classrooms, workplaces, or online.
-
The Right to Bear Arms (Second Amendment): Continues to inform conversations and education in SDI’s School of Firearms Technology.
-
Due Process (Fifth and Fourteenth Amendments): Secures fairness in law and education, impacting each of us directly.
How You Can Mark the Day

-
Thank a veteran or service member who has lived out their commitment to defend the Constitution.
This Constitution Day, SDI celebrates 230 years of liberty and honors those who continue to protect it.
