Understanding Kentucky's Time Zones: Eastern and Central Time Explained
When planning travel, making business calls, or watching scheduled broadcasts in the state of Kentucky, knowing the correct time zone is essential. Kentucky is unique because it spans two time zones: Eastern Time and Central Time. This division can cause confusion, especially for visitors or new residents. In this guide, you’ll find a clear explanation of Kentucky’s time zones, which counties fall into which zone, and how to avoid common time-related mix-ups.
Which Time Zones Does Kentucky Observe?
Kentucky observes two United States time zones:
- Eastern Time Zone (ET) – Also referred to as Eastern Standard Time (EST) or Eastern Daylight Time (EDT) during daylight saving.
- Central Time Zone (CT) – Known as Central Standard Time (CST) or Central Daylight Time (CDT) when daylight saving is active.
Unlike most U.S. states that fall entirely within one time zone, Kentucky's time zone is split almost directly down the middle. The exact division is based on county lines.
Where Does the Time Zone Change in Kentucky?
The time zone boundary in Kentucky runs west to east through the state. In general:
- The eastern half of Kentucky uses Eastern Time.
- The western half of the state uses Central Time.
This makes Kentucky one of the states with a time zone split by county. For local residents and travelers alike, it's important to know which side of the line you're on.
Eastern Time Zone Counties in Kentucky
Counties in the Eastern Time Zone include:
- Fayette County (Lexington)
- Franklin County (Frankfort – the state capital)
- Jefferson County (Louisville – although close to the border, it's in Eastern Time)
- Boyd County (Ashland)
- Rowan County
- Bell County
- Many others in the central-to-eastern part of the state
If you’re in or near Lexington, Louisville, or Frankfort, you are most likely in the Eastern Time Zone.
Central Time Zone Counties in Kentucky
Counties in the Central Time Zone include:
- Warren County (Bowling Green)
- Christian County (Hopkinsville)
- Daviess County (Owensboro)
- McCracken County (Paducah)
- Hardin County (Elizabethtown)
- Many counties in western and south-central Kentucky
Western Kentucky, including cities like Bowling Green and Owensboro, is firmly in the Central Time Zone.
Daylight Saving Time in Kentucky
Both time zones in Kentucky observe Daylight Saving Time (DST). This means:
- Eastern Standard Time (EST) becomes Eastern Daylight Time (EDT)
- Central Standard Time (CST) becomes Central Daylight Time (CDT)
The switch typically occurs:
- Second Sunday in March – clocks move forward by one hour
- First Sunday in November – clocks move back by one hour
Because both time zones in Kentucky observe this change, the hour difference between regions remains consistent throughout the year.
How to Handle Time Zone Differences in Kentucky
If you're coordinating meetings or traveling across Kentucky, here are some tips to manage the time zone shift:
- Use GPS apps or online maps that show time zones by location
- Double-check local time for counties near the boundary
- Be aware that media broadcasts and event times may be listed in either zone
- When scheduling, confirm the recipient’s local time
Time zone confusion is common along the dividing line, especially with cities that are close to the border. Being proactive can help you stay on schedule.
Why Kentucky Has Two Time Zones
The split in Kentucky’s time zones is based on historical and geographical factors. The U.S. time zone system aligns roughly with economic ties, transportation routes, and population centers.
Counties in eastern Kentucky often align more closely with time schedules in places like Ohio and West Virginia, which follow Eastern Time. In contrast, western Kentucky is closely connected with Tennessee and Missouri, which are in the Central Time Zone.
The current boundary was set to reflect these commercial and social connections.
Common Questions About Kentucky Time Zones
Does Louisville use Central or Eastern Time?
Louisville is in the Eastern Time Zone. Despite being in northwestern Kentucky near the border, it observes Eastern Time year-round.
Is Bowling Green Kentucky in the Central Time Zone?
Yes. Bowling Green, located in Warren County, is in the Central Time Zone.
What’s the time difference between Eastern and Central Time Zones?
The time difference is one hour. Eastern Time is one hour ahead of Central Time. If it’s 3:00 PM in Lexington (ET), it’s 2:00 PM in Bowling Green (CT).
How do I know what time zone I’m in while traveling in Kentucky?
Use your smartphone’s time zone detection or refer to official road signs along major highways. Signs usually indicate when you cross from one time zone into another.
Why Understanding Kentucky’s Time Zones Matters
Knowing Kentucky’s time zones can help you:
- Arrive on time for meetings, appointments, or family events
- Plan trips or routes more effectively
- Coordinate with local businesses and services accurately

Whether you live in Kentucky, work with people in the state, or are visiting, being aware of the time zone split prevents coordination errors and delays.
