Overview
- Clocks moved back one hour at 2 a.m. Sunday as most of the U.S. returned to standard time, with many devices updating automatically.
- Standard time now runs until March 8, 2026, when daylight saving time is scheduled to resume.
- Hawaii, most of Arizona, and territories including Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Northern Mariana Islands do not change clocks.
- Under the Uniform Time Act, states may adopt year-round standard time but cannot unilaterally switch to permanent daylight saving time, leaving 19 states’ DST laws pending federal approval.
- Congressional efforts to end the twice-yearly change remain stalled after an Oct. 28 fast‑track attempt was blocked, as major medical groups and new research back permanent standard time for health.
