2024 time change dates for Tennessee
At 2:00 AM the clocks jump straight to 3:00 AM in Tennessee. That hour never happens, and everyone loses an hour of sleep.
At 2:00 AM the clocks return to 1:00 AM, so that hour is lived through twice and the night is an hour longer.
Tennessee keeps CST/EST in winter and shifts one hour forward for the summer.

Health Considerations for Tennessee Residents
The spring transition is the one that hurts. A study in Open Heart found the risk of heart attack rose by about 24% on the Monday after clocks went forward, before falling back to normal within the week. Research published in Current Biology found a 6% rise in fatal traffic accidents in the week following the spring change, with the effect strongest in the morning and in the western parts of time zones.
The autumn change, when most people gain an hour, shows no comparable spike. Researchers attribute the difference to sleep loss rather than to the clock change itself.
Background
- The spring transition is associated with a measurable short-term rise in heart attacks and fatal traffic crashes, an effect researchers attribute to the lost hour of sleep rather than the clock itself.
- Russia experimented with permanent summer time from 2011 to 2014 before settling on permanent standard time.
- The Energy Policy Act of 2005 extended US DST by four weeks starting in 2007, moving the start to the second Sunday in March and the end to the first Sunday in November.
Tips for Tennessee
Set your clocks before going to bed to avoid confusion in the morning.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Check and replace smoke detector batteries when changing clocks - it's a good reminder!
Be extra cautious driving the Monday after the spring time change - accident rates increase.
Frequently asked questions
When do the clocks change in Tennessee in 2024?
Clocks go forward on Sunday, March 10, 2024 and back on Sunday, November 3, 2024.
Which way do the clocks go?
"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.
Do I have to change anything myself?
Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.
Is Daylight Saving Time being scrapped?
It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
