Several eastern Indiana counties (Ohio and Dearborn counties, near Cincinnati; and Floyd, Clark, and Harrison counties, near Louisville) chose to unofficially observe daylight saving time, despite the Indiana statute.Four years later, Starke County asked the USDOT to move it from the Central Time Zone to the Eastern Time Zone; in this case, however they did not find a sound reason for the move, and declined the request (see 46 FR 23500 and 46 FR 51786).The other 82 counties were in the Eastern Time Zone and did not observe DST; however, six counties near Louisville, KY, and Cincinnati, OH, unofficially observed DST.

Indiana enacted the statute, officially placing northwest and southwest Indiana in the Central Time Zone, in observance of daylight saving time, and the rest of the state in the Eastern Standard Time throughout the year.The state capital in Indianapolis lies at approximately the 86th meridian (U.

Time zones were first adopted by the United States Congress with the Standard Time Act of 1918.
The Indiana General Assembly passed a law to make Central Time the official time zone of the state in 1957, but permitted any community to switch to daylight saving time during the summer.
