Constitution Day is celebrated on 9 July, the date the Constitution became law in 1900. The date is not a public holiday. Constitution Day was first held on 9 July 2000 to mark the centenary of the Constitution as part of the Centenary of Federation. The celebrations were not big and have not been widely held after 2001. Constitution Day was revived in 2007 and is jointly organised by the National Archives of Australia, which holds the original Constitution documents, and the Department of Immigration and Citizenship.
