What is Constitution Day?

Constitution Day is a US holiday in celebration of the Constitution of the United States and its signing in 1787.

Constitution Day is typically observed with educational activities pertaining to the Constitution and the rights that it protects. It is a relatively recent holiday and is not well-known or widely observed compared to other patriotic holidays in the US, such as Independence Day.

A holiday known as Citizenship Day is held on the same day, and observance of the two holidays is often combined as an opportunity to learn more about the US, its laws, and its people.

⚡️When is Constitution Day?

Where does Constitution Day come from?

Constitution Day was first observed in 2005. Adoption of the holiday was a result of a campaign started in the 1990s by Louise Leigh, who founded an organization to promote the day. The day was officially adopted in 2004.

September 17 has been observed in the US as Citizenship Day since much earlier. A day to celebrate US citizenship was suggested by influential newspaper publisher William Randolph Hearst in 1939. In 1940, a resolution was passed declaring the third Sunday in May as I Am an American Day, a day initially dedicated primarily to those who had recently become US citizens.

In 1952, Olga T. Weber petitioned the leaders of her hometown of Louisville, Ohio, to change the date of I Am an American Day to coincide with the date of the signing of the US Constitution. Her request was granted, and she went on to successfully request the same change statewide and then nationwide. In 1953, the day was officially moved to September 17 and renamed Citizenship Day on a national level.
