Clocks go back one hour at 2 a.m. on Sunday, November 1, 2026. This page times your sleep to the new clock using three nights of small adjustments beforehand and two managed mornings after, at about ten minutes of effort a day.

The thing to know before you start: falling back asks your body clock to delay, which is the gentler of the two directions, but the extra hour on the clock does not hand you an extra hour of rest. Your light exposure is still sitting exactly where it was, and that is what your body is reading.

What you need

  • Any clocks you set by hand

    Oven, car, wall clock. Set them back before bed on Saturday, October 31, not on Sunday morning.

  • A way to get outdoors in the first hour after waking

    On a cloudy morning, open the curtains and sit by the window instead. The lab study behind this advice used one hour of bright light at 8,000 lux to move circadian timing.

  • Lamps you can turn down for the two hours before bed

    Evening light is the strongest timing cue the body clock has, which is why dimming counts as an intervention and not a mood choice.

  • Seven protected hours on Sunday night

    Eight if there is a teenager in the house. That is the AASM minimum for the nights around a transition.

  • A cleared Sunday and Monday

    No long drives, no task that punishes one lapse of attention. Patient safety incidents traced to human error rise 18.7% around clock transitions.

Three nights before, two mornings after

  • Thursday, October 29: go to bed 20 minutes later than usual, and get up 20 minutes later

    Later, not earlier. You are pre-paying the delay the clock will demand on Sunday. It should feel like almost nothing; if you are lying awake, you moved too far.

  • Friday, October 30: move bedtime and wake time another 20 minutes later

    You are now 40 minutes off your normal schedule. Push dinner back by the same amount. Mealtime is a routine cue the AASM specifically suggests shifting with the sleep schedule.

  • Saturday, October 31: move another 20 minutes later, then set your manual clocks back before bed

    You are a full hour later than your usual bedtime. After the change, that same moment reads as your normal bedtime, which is the point.

  • Sunday, November 1: get up at your usual clock time and go outside within an hour

    Do not sleep in on the gained hour. Holding the wake time is what stops the week from unraveling.

  • Sunday evening: turn the lights down for the two hours before bed, screens off for the last 30 minutes

    Dim light lets melatonin onset land where you want it. The signal is feeling sleepy at your normal bedtime rather than at 8 p.m.

  • Monday, November 2: same wake time, same morning light, and nothing demanding on the calendar

    Two consistent mornings do more than one. By midweek, bedtime and wake time should be holding without effort.

Which light matters more depends on your problem. A pilot study using wrist-worn circadian monitors on eight adults found that around the fall transition, morning light produced phase advances of about 0.87 hours while evening light produced delays of about 0.63 hours. Morning light is the stronger lever, and it pulls your clock earlier. That helps if you are dragging at 7 a.m. It works against you if you are already snapping awake at 4.

If you're awake at 4am on Monday

Stop chasing the sunrise and move your light to the other end of the day. Keep the lamps up through the early evening and start the dim-down two hours before bed rather than at dusk. Your body clock is sitting ahead of the new clock time, and morning light will only pull it further forward.

Probably not. The AASM is explicit that the nominal extra hour does not guarantee better rest, because it does not move the light your body was already reading. Most transition effects resolve over roughly a week. If early waking is still there after two weeks, the clock change is no longer the explanation, and it is worth looking at what else fragments the back half of your night, including alcohol, a warm bedroom, or untreated snoring.

The pre-shift does not, because your sleep is not anchored to clock evening in the first place. The light rules still apply, just tied to your own wake time rather than the sun. The mechanics are different enough that it needs its own method: see the approach for [working a night shift](/how-to-sleep-better-working-night-shift-without-fighting-your-body-clock/).

It can help realign timing, but Sleep Foundation's medical reviewer frames it as something to use in consultation with your doctor, not as a default. Dose and timing decide whether it shifts your clock forward, backward, or not at all. Light is free, better evidenced for this specific job, and harder to get wrong.

Will there still be a clock change next year?

Not settled, and it does not change what you do in November. The Sunshine Protection Act, which would end the biannual switch by making daylight saving time permanent, passed the House on July 14, 2026 and then sat in the Senate Commerce, Science and Transportation Committee. It would have needed Senate passage and a signature before November 1 to stop this year's change, and as of mid-September reporting that had not happened.

Worth knowing which permanent option the sleep doctors want, because the bills disagree. The AASM's position statement, published in October 2023 and endorsed by around 20 medical and scientific organizations, backs permanent standard time, not permanent daylight time. The argument is about morning light: permanent DST would push sunrise later by the clock through the winter, delaying the cue that anchors the body clock. A separate bipartisan bill, the Sunshine for Our Kids Act from Reps. Mary Gay Scanlon and Pat Harrigan, would do the opposite of the House bill and lock in standard time. Some 63% of Americans want the switching to stop; there is no such agreement on where to stop it.

By the Wednesday after the change you should be falling asleep and waking at your normal clock times without thinking about it. If you are not, the next thing to audit is the drink you had at 3 p.m., because caffeine's half-life runs long enough in some people to still be working at midnight, whatever the clock says.
