U.S. Clocks Fall Back at 2 A.M. as Daylight Saving Time Ends

A late bid to end the biannual switch failed in the Senate this week after Sen. Tom Cotton blocked a fast-track vote.

Overview

  • Clocks are set back one hour at 2 a.m. local time Sunday, bringing earlier sunrises and earlier sunsets through the winter.
  • Hawaii, most of Arizona, and territories including Puerto Rico and Guam remain on standard time year-round and do not change clocks.
  • The latest effort to make daylight saving time permanent stalled after Cotton opposed Sen. Rick Scott’s Sunshine Protection Act, which previously cleared the Senate in 2022 but never reached a House vote.
  • Roughly 19 states have passed laws to adopt year-round daylight saving time but cannot implement them without congressional approval, though states may choose permanent standard time on their own.
  • Major medical groups favor permanent standard time and warn of health and safety risks from clock changes; experts and the CDC recommend morning sunlight and consistent bedtimes, and the next switch back to daylight saving time is March 8, 2026.
