The short answer In 2026, daylight saving time ends at 2:00 am on Sunday, November 1, when clocks go back to 1:00 am. Most adults adjust within a day or two. To bank the extra hour, go to bed at your usual time Saturday, set the clocks back just before lights out and wake at your usual time. Early risers and young kids do better shifting bedtime later over a few nights beforehand.
The fall change is the gentler of the two. Your body clock finds it easier to run late than to run early, so gaining an hour is easier than losing one. It still trips up early risers, small children and anyone whose mood dips when the evenings go dark. Here’s a plan for the week.
When is the time change in 2026?
Daylight saving time ends at 2:00 am local time on Sunday, November 1, 2026, according to the National Institute of Standards and Technology. Federal law sets the rule: the first Sunday in November at 2:00 am. At that moment clocks fall back to 1:00 am, so the hour from 1:00 to 2:00 happens twice. Hawaii and most of Arizona don’t observe daylight saving time, so nothing changes there.
Phones and connected devices update on their own. Oven clocks, car dashboards and older alarm clocks don’t, so set those Saturday night.
Your fall-back plan
- Decide what you want the hour for. If you’re short on sleep, use it to start an earlier bedtime. If you already sleep well and wake early, the goal is to keep your body clock from waking you an hour ahead of the alarm all week.
- Early riser or young kids? Start Wednesday or Thursday. Push bedtime, wake time and meals about 15 minutes later each day. By Sunday you’re most of the way to the new clock. This is common clinical advice rather than something trials have tested, but it follows the same logic as the CDC’s guidance to shift your schedule before a trip across time zones.
- Saturday night, change the clocks at bedtime. The American Academy of Sleep Medicine suggests going to bed at your usual bedtime, setting your clocks back one hour just before getting into bed, and waking at your regular time. That gives you one more hour of sleep.
- Sunday morning, keep the early light low. If you wake before the alarm, keep the room dim. For travelers flying west, which is the same direction of shift, the CDC advises avoiding bright light in the early morning, using shades or sunglasses.
- Get light in the late afternoon and evening. The CDC notes that light exposure in the evening generally pushes the body clock later, which is exactly the direction you need for the first few days.
- Live by the new clock from Sunday on. Eat, exercise and go to bed on the new time. Keep caffeine on its usual clock-time cutoff; our caffeine calculator shows what’s left at bedtime.
- Keep naps short. Afternoon slumps are common the first days. A brief early-afternoon nap is fine; a long late one makes the new bedtime harder. See how long a nap should be.
- Hold the new wake time through the weekend after. One fixed wake time does more to settle your body clock than anything else. The AASM’s advice is to get up at the same time every day, even on weekends.
Do you really get an extra hour of sleep?
On Sunday, most people do. In a UK Biobank study of 11,780 adults wearing activity trackers, sleep on the fall clock-change Sunday was about 33 minutes longer than the Sunday before. On the spring change, it was about 65 minutes shorter.
The week after can go the other way for some. A small study that tracked 14 university students with wrist monitors found that after the fall change they got up earlier and slept less in the following week. The authors still found the spring change disrupted sleep more, which fits how the body clock works: delaying is easier than advancing.
That’s why early risers notice the fall change most. If you naturally wake at 6:00, your body clock now says 6:00 when the wall clock reads 5:00.
How long does it take to adjust to falling back?
For most adults, a day or two. The CDC’s travel guide estimates people adapt to westward shifts at about 1.5 hours per day, and the fall change is a one-hour shift in the same direction. People whose wake-up time is set by their body clock rather than an alarm, like early risers and young children, tend to notice it most.
If you’re still waking an hour early after a week, look at evening light and bedtime before anything else. A bedtime that’s drifted earlier with the darker evenings will keep pulling your wake-up earlier too. Our bedtime guide and sleep calculator can help reset the target.
Using the time change to fix a too-late bedtime
If you’ve been getting less than 7 hours, the AASM sees the fall change as a chance to adopt an earlier bedtime. Go to bed Saturday at your normal time, take the extra hour, notice how you feel, and then keep going to bed at that same body-clock time, which is now an hour earlier on the wall clock.
The AASM is blunt that one extra hour won’t erase a chronic sleep debt. But waking up feeling more alert can make the earlier bedtime easier to stick with.
Darker evenings: driving and mood
After the change, the evening commute happens in the dark for much of the country. Studies of US crash data have linked darkness to more fatal crashes. One analysis estimated that year-round daylight saving time would cut pedestrian deaths by about 13% in the morning and evening commuting hours. Slow down, watch for walkers, and if you’re drowsy behind the wheel, pull over.
Mood can take a hit too. A Danish study of 185,419 hospital contacts for depression found the switch to standard time was followed by an 11% rise in new depressive episodes, fading over about 10 weeks. The authors suspected the sudden earlier sunset, which marks the start of a long stretch of short days. Midday daylight and regular outdoor time are worth protecting through November.
When to see a doctor
- Low mood, loss of interest, oversleeping or carb cravings that start in late fall and last more than two weeks can be seasonal affective disorder. The National Institute of Mental Health notes it usually starts in late fall or early winter, and it’s treatable.
- If you’re still waking far too early weeks after the change, or you’ve had trouble sleeping at least three nights a week for three months, that’s worth raising with a doctor. Chronic insomnia responds well to cognitive behavioral therapy for insomnia (CBT-I).
- Feeling exhausted even after a full night’s sleep can signal sleep apnea or another sleep disorder.
Why sleep doctors want to stop changing the clocks
The AASM’s position is that the US should eliminate seasonal time changes in favor of permanent standard time, which aligns best with human biology. In its 2024 statement it notes that even the fall transition, often seen as harmless because of the extra hour, has been associated with sleep disruption, mood disturbance and traffic accidents.
Standard time is what we’re switching to on November 1. In the sleep doctors’ view, it’s the setting the clocks should have stayed on.

Common questions
When do the clocks fall back in 2026?
Daylight saving time ends at 2:00 am local time on Sunday, November 1, 2026, when clocks go back to 1:00 am. Hawaii and most of Arizona don't change.
Do we gain or lose an hour of sleep in November?
You gain an hour. If you go to bed at your usual time Saturday and wake at your usual time Sunday by the new clock, you get one extra hour in bed.
How long does it take to adjust to the fall time change?
Most adults adjust within a day or two, since the body clock shifts later fairly easily. Early risers and young children tend to notice it more, often waking an hour early at first.
Why do I wake up so early after the clocks go back?
Your body clock hasn't moved yet, so when it says 6:00 the wall clock reads 5:00. Keeping early-morning light low and getting light in the evening helps it shift later.
