About this clock
Chattanooga does not keep Tennessee's usual time
Most of Tennessee is on Central Standard Time, but Chattanooga keeps Eastern Standard Time — 1 hour ahead of the rest of the state. This is the kind of thing that catches people out, and it is why the zone is resolved from the city’s own coordinates rather than assumed from the state.
Chattanooga is currently on standard time. The next change is Sunday, March 14, 2027, when 2:00 am becomes 3:00 am local time.
Chattanooga sits at 35.07°N, 85.25°W. For sunrise and sunset there — which do depend on exactly where it is, unlike the clock — see sunrise and sunset in Chattanooga.
Clock time against sun time
The clock says the same thing everywhere in Eastern Standard Time, but the sun does not. Over Chattanooga it is highest at 12:25 pm today — 25 minutes after clock noon.
At 85.2°W, Chattanooga sits 41 minutes of solar time west of Eastern Standard Time’s 75° meridian, so on standard time the sun peaks 41 minutes after noon.
