Overview
- Most of the United States will set clocks back one hour to Standard Time at 2 a.m. local time on Sunday, Nov. 1, returning mornings to earlier sunrises and evenings to earlier sunsets for the winter.
- The U.S. House passed the Sunshine Protection Act in July to make daylight saving time permanent, but the measure has stalled in the Senate and faces no clear path to the 60 votes needed for floor action.
- President Donald Trump and business groups have publicly pressed senators to act, arguing year‑round daylight saving would boost sports, tourism and evening commerce.
- Major medical organizations and recent research, including a Stanford study, say permanent standard time better fits human circadian biology and warn that shifts or permanent DST are linked to spikes in heart attacks, crashes and sleep disruption.
- Several states and Canadian provinces have passed laws for permanent time but those laws cannot take effect without federal authorization, so jurisdictions such as Texas must still change clocks and, unless Congress acts, will move clocks forward again in March 2027.
