Overview

• At 2:00 a.m. on Sunday, Nov. 2, clocks shift back to 1:00 a.m., with local reminders issued for places like New Jersey and Pennsylvania.
• Analog clocks and some alarm clocks may require manual adjustment before bed, while smartphones, computers and smartwatches typically update on their own.
• Arizona (except the Navajo Nation), Hawaii, Puerto Rico, Guam, American Samoa and the U.S. Virgin Islands do not observe the change.
• Experts note short-term sleep disruption and a temporary rise in traffic crashes after the switch, and they recommend gradual sleep adjustments and household safety checks such as smoke detectors.
• The Uniform Time Act, as amended by the Energy Policy Act of 2005, sets the current schedule, and no federal change has been enacted for 2025; the next switch to daylight time is March 8, 2026.
