Citizenship Day, also known as Constitution Day, is a federal holiday in the U.S. and is observed on the third Friday in September; this year on September 17th. On this day in 1787, the adoption of the United States Constitution was signed by delegates to the Constitutional Convention in Philadelphia. This event commemorates also all the people who are taking steps to become U.S. citizens and those who become citizens by coming of age or by naturalization.
The origins of this celebration goes back to 1940 when the day was called “I am an American Day” and celebrated on the third Sunday in May each year. Later the day was renamed Citizenship Day and moved to September 17th by the Congress.
The law establishing the holiday was created in 2004 with the passage of an amendment by Senator Robert Byrd to the Omnibus spending bill of 2004. Before this law was enacted, the holiday was known as “Citizenship Day.” In addition to renaming the holiday “Constitution Day and Citizenship Day,” the act mandates that all publicly funded educational institutions provide educational programming on the history of the American Constitution on that day. In May 2005, the United States Department of Education announced the enactment of this law and that it would apply to any school receiving federal funds of any kind. This holiday is not observed by granting time off work for federal employees.
When Constitution Day falls on a weekend or on another holiday, schools and other institutions observe the holiday on an adjacent weekday. Universities and colleges nationwide have created “U.S. Constitution and Citizenship Weeks” in order to meet the requirements of the law. (from Wikipedia and www.cute-calendar.com)
