Indiana Day is a legal holiday in the U.S. state of Indiana commemorating the admission of the state into the Union. It was first instituted in 1925 by the Indiana General Assembly. The Indiana Code directs the governor to issue an annual proclamation to observe December 11 as the day statehood was granted to Indiana by the United States Congress and the state's admission to the Union. The law also requires state schools to hold appropriate events to commemorate the event and authorizes public celebrations to be held. Historically the day is commemorated in Indianapolis with speeches and events in the Indiana Statehouse. The day is not a paid holiday, and government employees work on the day.
