Most of the state is in Eastern Time (80 of the 92 counties), but some of the most populated parts of the state are in Central Time. When Indiana residents travel within the state or try to watch a broadcast from Indianapolis, it's a constant pain to remember the time zone difference. World time: United States, Indiana, Indianapolis. 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 Eastern Standard Time throughout the year.
Supporters of daylight saving time and a common time zone in Indiana often assert that Indiana must adopt the Eastern United States timing system to preserve interstate business with that region. But in 1985, the Indiana General Assembly, in Senate Concurrent Resolution 6 of 1985, called on the USDOT to move five southwestern Indiana counties (Posey, Vanderburgh, Warrick, Spencer and Gibson) from the central time zone to the eastern time zone. Several counties in eastern Indiana (Ohio and Dearborn Counties, near Cincinnati; and Floyd, Clark and Harrison Counties, near Louisville) chose to unofficially observe daylight saving time, despite Indiana law. But one of the biggest controversies about living in Indianapolis that you probably won't consider until you live there is the multiple time zones within the state of Indiana.
