Constitution Day is a holiday that commemorates the formation and signing of a country's constitution. In the United States, Constitution Day specifically honors the signing of the U.S. Constitution, which took place on September 17, 1787. This day recognizes the adoption of the Constitution and celebrates those who have become U.S. citizens by birth or naturalization. It is observed annually on September 17 and marked by educational programs about the history and significance of the Constitution, particularly in publicly funded schools and federal agencies. Constitution Day also kicks off Constitution Week in the U.S., extending through September 23. The holiday combines honoring the founding document with citizenship, featuring events like naturalization ceremonies and educational activities.
More broadly, many countries have their own Constitution Day, often celebrated on the anniversary of their constitution's signing or adoption to honor their nation's legal foundation.
