In most of the United States, daylight saving time ends at 2:00 a.m. on Sunday, November 1, 2026. Clocks move back one hour, giving many people an extra hour on the clock that morning. The change is simple, but it can affect sleep routines, appointments, travel plans, and the amount of daylight available after work.
Some places do not observe daylight saving time, including most of Arizona and Hawaii. If you are traveling or coordinating with people in different states, confirm the local time rather than assuming every location changes clocks.
What should you change before November 1?
- Check manual clocks. Update wall clocks, ovens, car clocks, and older watches before bed Saturday night.
- Confirm digital devices. Phones and computers usually update automatically when time-zone settings are correct. Check alarms and calendar events if you recently traveled or changed settings.
- Review appointments. Recheck flights, telehealth visits, work shifts, childcare pickup, and any event scheduled around the transition.
- Test smoke and carbon monoxide alarms. The seasonal clock change is a useful reminder to test alarms and replace batteries when needed. Follow the device maker’s instructions.
- Prepare for earlier darkness. Check outdoor lights, reflective clothing, bike lights, and visibility around driveways and walkways.
How to make the time change easier on sleep
Even when the clocks move back, a sudden change in routine can leave some people groggy. In the days before the change, keep a consistent bedtime and wake time, get daylight during the morning, and avoid making a large shift in caffeine or alcohol habits. A calm evening routine can help your body settle into the new schedule.
If you work overnight or rotating shifts, confirm your employer’s timekeeping rules. The clock change can make a shift appear longer or shorter, and payroll treatment depends on the employer’s policy and applicable law.
Does every U.S. state change its clocks?
No. Federal law allows states to exempt themselves from daylight saving time. Hawaii and most of Arizona do not observe it; some U.S. territories also stay on standard time year-round. Tribal lands in Arizona may follow different rules from the surrounding state. For travel, check the time zone for the specific destination.
