Tennesseans will turn their clocks back one hour early Sunday morning, but a federal proposal could eventually end the twice-yearly time change.
Daylight saving time ends at 2 a.m. Sunday, Nov. 1, meaning clocks will move back one hour to standard time.
This could be the last year Americans make the switch if Congress approves a proposal to keep daylight saving time year-round. However, the bill has not cleared the Senate, so the current schedule remains in place.
The House approved the Sunshine Protection Act of 2025, H.R. 139, by a 308-117 vote on July 14. Sponsored by Rep. Vern Buchanan, R-Fla., the bill was sent to the Senate the next day and referred to the Senate Committee on Commerce, Science, and Transportation.
The Senate has not approved the bill. Senators are expected to return to Washington Nov. 9, when the proposal could receive renewed attention. However, some senators oppose the change because it would mean darker winter mornings, including for children walking to school.
Under the proposal, clocks would no longer change twice a year. Permanent daylight saving time would mean more evening daylight but later sunrises during winter. Permanent standard time would mean earlier sunrises and sunsets.
Supporters of permanent daylight saving time want to keep evenings brighter and eliminate the clock changes. Opponents are concerned about darker mornings during school and work commutes.
Tennessee and 18 other states have passed laws supporting year-round daylight saving time if federal law allows it. Arizona and Hawaii do not observe daylight saving time and do not change their clocks twice a year.
For now, Tennesseans should plan to turn their clocks back Sunday as the federal proposal awaits further action in the Senate.
