When Do the Clocks Change in Tennessee?

Time Zones in Tennessee

Tennessee is not on a single clock. It spans 2 zones, which is why two places inside the same state can be an hour apart.

Where the line falls. The line runs down the Cumberland Plateau, splitting the state between Knoxville and Nashville — the two largest cities are permanently an hour apart.

What Actually Changes: Sunrise and Sunset

The hour on the clock is not the part anyone notices. This is what the change does to daylight in Nashville, comparing the day before with the day after.

The amount of daylight barely moves across those two days — roughly the same number of hours either side. What moves is where those hours sit: the clock change shifts them from the evening to the morning, or back again. Full sunrise and sunset detail for Nashville.

What Stands Out About Tennessee

Solar noon is at 12:33 PM, not noon

The sun reaches its highest point over Nashville at 12:33 PM, so the clock runs 34 minutes ahead of the sun. That gap has nothing to do with Daylight Saving Time and never changes: it is simply where Tennessee sits inside an hour-wide time zone.

Daylight swings by 4h 55m across the year

Nashville gets 14h 37m of daylight at midsummer and 9h 42m in December. The clock change does not add or remove any of that — it moves an hour of it from the evening to the morning, which is why the same rule feels completely different in June and November.

One clock, 25 minutes of real difference

Memphis and Knoxville read exactly the same time, but they are 6.1 degrees of longitude apart — about 25 minutes of real solar time. The sun sets that much later at the western end of Tennessee than the eastern end, every single day, and no clock change affects it.

Dark before the working day ends

After the change the sun sets in Nashville at 4:50 PM. For most of the winter that means leaving work in the dark, which is the single most common complaint about the November change and the reason states keep voting for permanent Daylight Saving Time they are not allowed to adopt.

The clock changes at the state line

Tennessee borders 4 states on a different clock right now: Kentucky, Virginia, North Carolina, Georgia. Crossing any of those borders moves the time, which matters for anyone commuting, delivering or scheduling across the line — and for phones, which switch silently and without asking.

The Next Clock Changes in Tennessee

The next move is backwards, which is the one people notice: an hour more sleep, and sunset arriving before most of the working day is over. US clocks change on the second Sunday in March and the first Sunday in November. These are the next dates that rule produces for Tennessee, computed from the current time zone rules rather than a fixed list — if the rules change, these dates change with them.

The Two Halves of Tennessee

Right now the two sides of Tennessee are 1 hour apart. That gap holds all year, because both sides change their clocks on the same dates — they simply start from different offsets.

Why Tennessee Keeps the Clock It Does

Tennessee is the clearest case in the country of a time zone line cutting a state in half: Nashville and Knoxville are 180 miles apart and always an hour out of step. The state passed a permanent Daylight Saving Time bill in 2019 that would apply only to its Eastern-zone counties.

The practical consequence is that every time difference involving Tennessee shifts by an hour on Sunday, November 1, 2026 — and with 4 neighbouring states already on a different clock, this is a state where knowing the date matters at the border as much as it does across the country.

Crossing the State Line

These neighbouring states are on a different clock from Tennessee today. A state border is the most common place to lose or gain an hour without expecting to.
