Constitution Day is important because it commemorates the signing of the United States Constitution on September 17, 1787, a pivotal document that laid the foundation for the nation's democratic principles, rights, and freedoms. It celebrates the enduring values of democracy, the rule of law, and individual rights protected by this "living" document, which serves as a model for democratic governance both in the U.S. and worldwide. Constitution Day also fosters awareness of the responsibilities of citizenship and the significance of the Constitution in protecting liberties against tyranny, promoting justice, and maintaining a balanced government through its system of checks and balances. It is a day to reflect on the historical and ongoing importance of constitutional governance in securing liberty and justice for all citizens.
