Chattanooga time zone and UTC offset
The local standard in Chattanooga is EDT — UTC-04:00, or 4 hours behind UTC. Systems that store time zones by name use America/New_York for this part of the world.
This zone does shift. On Sunday, 01 November 2026 the clocks go back 1 hour and Chattanooga moves to EST, so anything booked across that date needs checking.

Population: about 181,099 — 90th largest of the 212 United States cities indexed here.
