Clocks Spring Forward Sunday as Daylight Saving Time Begins Across Most of the U.S.

Health experts warn the spring shift disrupts sleep, with studies linking it to short‑term spikes in crashes plus cardiovascular events.

Overview

  • Daylight saving time starts Sunday, March 8, 2026, at 2 a.m. local time when clocks jump to 3 a.m., then ends Nov. 1 at 2 a.m.
  • Most of the country observes the change, while Hawaii, most of Arizona, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands do not.
  • Federal rules under the Uniform Time Act keep the national schedule, allowing states to stay on standard time year‑round but barring permanent daylight saving time without congressional approval.
  • President Donald Trump has called for ending the biannual clock changes, yet the Senate blocked a late‑2025 bill that would have enabled year‑round daylight saving time at the state level.
  • British Columbia will make March 8 its final clock change, shifting to permanent daylight saving time and adding cross‑border inconsistencies with neighboring U.S. jurisdictions.
