Time in Indiana

The U.S. state of Indiana is divided into Eastern and Central time zones. The official dividing line has generally moved progressively west from its original location on the Indiana–Ohio border, to a position dividing Indiana down the middle, and finally to its current location along much of the Indiana–Illinois border. In April 2006, several southwestern and northwestern counties reverted to Central time.

As much of Indiana is on the western frontier of the Eastern time zone, there was opposition from many in the state to observing daylight saving time there for decades. In 2005, the Indiana General Assembly reached a decision to implement daylight saving time state-wide beginning in April 2006.
