Clocks fall back this Sunday. Here's what actually changes, and a simple four-day plan to keep your mornings from going sideways.

Sunday morning, November 1. Your phone says 6:05. Your body is convinced it's past seven. You're wide awake, the house is dead quiet, and you already know 3 p.m. is going to hurt.

What actually changes on November 1

• At 2:00 a.m. local time, clocks go back to 1:00 a.m. That night is 25 hours long.
• Sunrise jumps earlier on the clock. In Chicago, the sun comes up at 7:22 a.m. on October 31 and at 6:23 a.m. on November 1.
• Sunset moves earlier too, so it gets dark around dinner time.
• Your body clock doesn't change at all. It runs on its own rhythm and takes most of its cues from light.

That last point is why the week after the change can feel off. If you normally wake at 7:00, your body may feel ready to go at about 6:00 on the new clock. Your evening drags, your morning starts early, and it takes a few days for the two to line back up.

Hawaii and most of Arizona don't observe daylight saving time, so if you live there, nothing changes.

Do you really get an extra hour of sleep?

Only if you use it. If you go to bed at your usual clock time on Saturday night, you have an extra hour available. But your body may still wake at the old time, so the "extra hour" can show up as an early, wide-awake Sunday instead of a sleep-in.

Falling back gets less attention than springing forward, but it still moves the clock away from your body's timing. The American Academy of Sleep Medicine has pointed to these seasonal clock changes as a strain on the body clock and supports moving to permanent standard time.

The four-day plan (start Wednesday, October 28)

The easiest daylight saving time sleep adjustment is a gradual one: move your schedule 15 minutes later each day, so by Sunday your body is already living on the new clock. Here's what it looks like for someone who normally sleeps from 11:00 p.m. to 7:00 a.m.:

• Wednesday, Oct 28: bed at 11:15 p.m., up at 7:15 a.m.
• Thursday, Oct 29: bed at 11:30 p.m., up at 7:30 a.m.
• Friday, Oct 30: bed at 11:45 p.m., up at 7:45 a.m.
• Saturday, Oct 31: bed at 12:00 a.m., set your clocks back before you sleep.
• Sunday, Nov 1: up at 7:00 a.m. on the new clock. To your body, that's the 8:00 a.m. it's been easing toward all week.

If you can, move dinner and your evening wind-down along with it. And if four days of shifting doesn't fit your life, two days of 30 minutes each is still better than none.

No time for the plan? Do this instead

Plenty of people can't push their mornings later during a work week. If that's you:

• Keep your normal wake time on the new clock starting Sunday, and expect a few early mornings.
• Stay up 20 to 30 minutes later than usual on Sunday and Monday nights to help your body catch up.
• Keep any naps short and early, so you're actually tired at your new bedtime.
• Use the light tips below. Light is one of the most useful tools you have here.

Light is the real lever

Light is one of the strongest signals your body clock gets, so it's worth using on purpose during a time change.

• Mornings: get outside or sit near a bright window soon after you wake up. After November 1 there's more daylight on your commute, so use it.
• Evenings: once it's dark by dinner time, bright overhead lights and screens fill the gap. Ordinary room light before bed has been shown to push back the release of melatonin, so dim things down in the hour before sleep. How much it matters varies with how bright the light is, how long you're in it, and the person.

Keep your wake time steady afterward

Once you're through the change, one of the most helpful things you can do is wake up at about the same time every day, weekends included. Regular sleep and wake times are linked with better health and daytime performance, and big weekend swings act like a mini jet lag without the trip. For the bigger picture, see our guide to the science of waking up.

Who feels it most

• Early risers. If you already wake before your alarm, the change makes it earlier still. The four-day plan is worth trying here.
• Parents of young kids. Kids don't read clocks. We're covering a kid-specific plan later this week.
• Shift workers. Your schedule probably already fights your body clock. Protect your wake time and your light exposure on workdays.
• Couples on different schedules. One of you shifts, the other doesn't, and one alarm can wake you both.

Where TAVO fits

TAVO V2 is a wearable smart alarm. You choose a wake window, and it's designed to look for a suitable wake-up moment within that window, then wake you with a vibration on your wrist instead of a loud audible alarm. During a time change, you can move your window a little each day, and the vibration is designed to wake you, not the whole room.

We'd rather be straight with you: TAVO won't move your body clock for you. Light and a regular schedule do that. TAVO focuses on how you wake up.
