Overview
- Clocks in the United States moved back one hour at 2 a.m. on Sunday, November 2, 2025, marking the seasonal switch to standard time.
- Only designated northern border municipalities in Mexico adjusted clocks from 02:00 to 01:00, including all of Baja California and specified locales in Chihuahua, Coahuila, Nuevo León, and Tamaulipas.
- An AP‑NORC survey finds just 12% of U.S. adults support the current system, 47% oppose it, and, when choosing a single year‑round time, 56% prefer permanent daylight saving time.
- The Sunshine Protection Act to make daylight saving time permanent was reintroduced in 2025 after a 2022 Senate passage stalled in the House, and the next planned shift for participating U.S. jurisdictions is March 8, 2026.
- Medical groups advocate scrapping the semiannual changes and Stanford research indicates a single year‑round time is healthier for circadian rhythms, with modest advantages for permanent standard time.
