Time in Tennessee, as in all U.S. states, is regulated by the United States Department of Transportation.
About 73 percent of the counties in the state of Tennessee lie in the Central Time Zone, mostly the western and middle grand divisions, while East Tennessee is mostly in the Eastern Time Zone except for three counties in that division.[1][2]
All counties observe Daylight Saving Time.
