Daylight saving time ends tonight: clocks fall back at 2 a.m. nationwide
m. S.
At 2 a.m. local time on Sunday, November 1, 2026, clocks across most of the U.S. will fall back one hour, returning to standard time as daylight saving time officially ends, according to the National Institute of Standards and Technology and the U.S. Naval Observatory.
Key numbers
What happened
At 2 a.m. local time on Sunday, November 1, 2026, clocks across most of the U.S. will move back one hour, returning to standard time. This marks the end of daylight saving time for the year, with the hour between 1 a.m. and 2 a.m. repeating. The transition means mornings will become brighter earlier, while evenings will grow darker sooner by the clock.
Who is affected
Most Americans—those in states that observe daylight saving time—will be affected by the clock change. However, residents of Hawaii, most of Arizona (except the Navajo Nation), and U.S. territories including Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands will not change their clocks.
This act remains the legal framework governing the biannual clock changes.
What to do next
Most smartphones, computers, and internet-connected devices will adjust automatically. However, traditional clocks, car displays, kitchen appliances, and analog watches may require manual adjustment. Check and set these devices before bedtime on Saturday, October 31, to avoid confusion on Sunday morning.
What we know and don’t know
We know the exact time and date of the transition (2 a.m. on November 1, 2026) and which regions will observe it. However, we do not know whether Congress will pass legislation to make daylight saving time permanent, as the Sunshine Protection Act has not yet been approved by the Senate or signed into law.
Timeline of daylight saving time
- March 8, 2026: Daylight saving time begins at 2 a.m. local time.
- November 1, 2026: Daylight saving time ends at 2 a.m. local time.

Why it matters
The clock change can disrupt sleep patterns, particularly for those with early work schedules or children whose routines are tied to fixed times. Sleep scientists and doctors have proposed making standard time permanent to better align with human circadian rhythms, reducing health risks associated with disrupted sleep.
How to adjust to the time change
To ease the transition, maintain a consistent bedtime and wake-up time, expose yourself to natural morning light, avoid caffeine in the afternoon or evening, and keep bedroom lighting low before bedtime. Gradually adjust your schedule in the days leading up to the change to help your body clock adapt.
