Overview
- Clocks move from 2:00 a.m. to 3:00 a.m. local time on Sunday, March 8, then return from 2:00 a.m. to 1:00 a.m. on Sunday, November 1.
- Hawaii, most of Arizona, and several U.S. territories do not observe the change, while other states follow the DST schedule.
- The Uniform Time Act and subsequent amendments set the March–November framework, and permanent DST at the state level requires congressional approval.
- Smartphones, computers, and smartwatches usually update automatically, but ovens, microwaves, car dashboards, wall clocks, HVAC timers, and older security systems often need manual resets.
- Airlines, transit systems, hospitals, schools, financial markets, and major metros such as Los Angeles, San Francisco, Miami, New York, Dallas, and Houston are adjusting schedules, so travelers and shift workers should confirm bookings and plan sleep adjustments.
