Residents of Tennessee and millions of Americans will turn their clocks back one hour on November 1, 2026, as daylight saving time officially ends for the year. The mandatory time change takes effect at 2 a.m. local time, returning clocks to 1 a.m. and providing most people with an extra hour of sleep. Despite widespread public desire to end the twice-yearly ritual, the transition remains firmly in place because federal legislation required to make permanent changes has stalled in Congress.
Why Tennessee Still Changes Its Clocks
The annual fallback will occur as scheduled despite significant legislative groundwork laid within the state years ago. Tennessee adopted legislation in 2019 when Gov. Bill Lee signed a trigger law designed to establish permanent daylight saving time year-round. However, that state law includes a strict contingency: it cannot take effect unless Congress grants federal approval and the Tennessee General Assembly provides final certification.
Because federal lawmakers have failed to pass enabling legislation, Tennessee remains bound to the existing federal schedule managed under the Uniform Time Act of 1966 and the Energy Policy Act of 2005. The state observes daylight saving time from the beginning of March to the beginning of November, meaning standard time governs the state during the darker winter months.
The Stalled Sunshine Protection Act in Congress
At the center of the legislative delay is the Sunshine Protection Act, designated as H.R. 139, which was filed on January 3, 2025, by Rep. Vern Buchanan (R-Florida). The bill aims to make daylight saving time the permanent standard nationwide. Although the U.S. House of Representatives passed the measure on July 14, 2025, and the legislation has received vocal support from President Donald Trump, it has encountered a wall of opposition in the U.S. Senate.
Senate leadership and key members have pointed out that there is no clear path forward for the measure. During an October 2025 Senate floor speech, Sen. Tom Cotton (R-Arkansas) emerged as a vocal opponent, arguing that permanent daylight saving time would force millions of Americans-including school children-to travel to work and school in darkness during winter mornings. Senate Majority Leader John Thune noted that bipartisan concerns regarding public safety, especially in northern and rural school districts, have prevented the chamber from reaching a consensus.
States with Trigger Laws and Exceptions
Tennessee is far from alone in its legislative stance. A total of 19 states have enacted trigger laws or official legislation supporting year-round daylight saving time, ready to flip the switch if federal rules change. These states include:
- Alabama
- Colorado
- Delaware
- Florida
- Georgia
- Idaho
- Louisiana
- Maine
- Minnesota
- Mississippi
- Montana
- Oklahoma
- Oregon
- South Carolina
- Tennessee
- Texas
- Utah
- Washington
- Wyoming
Meanwhile, only two U.S. states-Hawaii and Arizona (excluding the Navajo Nation)-along with several U.S. territories, completely opt out of the biannual time change, choosing to remain on standard time year-round.
Historical Context and What’s Next
The concept of changing clocks dates back to World War I, implemented to conserve electricity. A permanent shift to year-round daylight saving time was previously attempted under President Richard Nixon in January 1974 to combat an ongoing energy crisis. That experiment was abandoned less than a year later, in October 1974, after reports of children commuting to school in pitch-black conditions and rising traffic accidents forced Congress to repeal the measure.
As the November 1 deadline approaches, Tennesseans must prepare to adjust their timekeeping devices manually. Unless Congress overcomes its legislative gridlock, the cycle of springing forward and falling back will continue, with the next scheduled clock change set for March 14, 2027.
