Daylight Saving After a Move: Kids' Sleep in Week One
The first clock change after you move somewhere at a different latitude is harder than the ones you knew at home, because two things shift at once: the clock jumps an hour, and the daylight your child’s body clock reads is running on a schedule you have never lived through. Treat it as a one-hour shift plus a light problem. Move bedtime in 15-minute steps over the four nights before the change, anchor every morning with outdoor light at the new wake time, and sort the room’s darkness before the weekend rather than after it. Most children are back on track within about a week.
Why the first clock change in a new place feels bigger
A child’s sleep is not set by the numbers on the kitchen clock. The US National Institute of General Medical Sciences puts it plainly: “light and dark have the biggest influence on circadian rhythms”, with food, activity and temperature playing smaller parts. At home, autumn dusk arrived when you expected it, and the clock change was a known one-hour wobble on top.
After a move, the wobble lands on a daylight pattern you have never seen. The further you are from the equator, the bigger the seasonal swing in day length, and the clock change sits right on top of a sunset that is already falling fast. I worked out the sunsets below with NOAA’s published sunrise and sunset equations, which NOAA says are accurate to within about a minute at these latitudes:
| City | Sunset, last day before the change | Sunset, first days after | Sunset at the December solstice |
|---|---|---|---|
| Miami | about 6:39pm (Oct 31) | about 5:38pm | about 5:34pm |
| Seattle | about 5:52pm (Oct 31) | about 4:49pm | about 4:20pm |
| Edinburgh | about 5:50pm (Oct 24) | about 4:45pm | about 3:39pm |
In Miami, the clock change is essentially the whole story. Once the hour has gone, sunset barely moves again until spring. In Seattle it keeps sliding another half hour after the change, and in Edinburgh another hour. So a family that moved from Florida to the Pacific Northwest over the summer is not getting “the clock change they know”. They are getting the clock change plus a steady retreat of evening light that never happened where they used to live. Week one is the start of the adjustment, not all of it.
The mornings move too. In Seattle, sunrise goes from about 7:52am to about 6:55am by the clock overnight, and in Edinburgh from about 8:02am to 7:06am. A child whose body wakes at first light is suddenly up at what the clock calls six.
Know which change you are actually getting, and when
Moving often means moving between rules, not just time zones, and it is easy to plan for the wrong Sunday:
- United States: in 2026, NIST lists daylight saving time as ending on November 1 at 2 a.m.. It also notes that Hawaii, Puerto Rico, Guam, the US Virgin Islands, American Samoa and Arizona (outside the Navajo Nation) do not observe it at all.
- United Kingdom: the clocks go back on 25 October 2026, a week earlier than the US.
- Southern hemisphere: clocks go forward in their spring. New Zealand changes on 27 September 2026 and New South Wales on 4 October 2026, and in Australia, Queensland, Western Australia and the Northern Territory do not change at all.
That mismatch reaches the rest of the family too. A family that moved from London to Sydney will see the time gap to the grandparents go from nine hours to ten on 4 October and to eleven on 25 October. A London–New York family gets a one-week window, between 25 October and 1 November, when the gap is four hours instead of five. Move the video call, never the bedtime. A standing call that suddenly lands at 7:30pm has quietly become a bedtime problem.
If you moved closer to the equator, or into a region with no clock change, the new place may be easier than the old one. Near the equator, sunset stays within a narrow band all year. What catches families out there is the old home’s change, through calls and school holidays back home, not their own.
The four-night plan
The time change itself is the familiar part, and the playbook I use for a one-hour time difference on a trip mostly carries over. What changes after a move is that you cannot lean on light cues you know, so you set them deliberately.
Shift in 15-minute steps. The NSW Government’s own advice is to adjust bedtime by 15 minutes each night before the change. For a fall-back weekend, move bedtime, naps and meals 15 minutes later each night from Wednesday, so that by Sunday the new 7pm is the time their body already expects. For a spring-forward change, go 15 minutes earlier instead. Betteroo’s pediatrician-reviewed guide sets out both the gradual shift and the cold-turkey reset for the time change, with notes by age. It points out that kids usually adjust within about a week either way.
Get light early, and outside. Both the NSW Government and the Sleep Foundation recommend morning light exposure to help the body re-set after the change. In a new city this matters more than it did at home, because the light is the part you do not yet know. Walk to breakfast, do the school run on foot, and eat the first meal by the brightest window in the house.
Fix the room for the new sunrise. If the change moves first light an hour earlier by the clock, a bedroom that was dark enough in September will not be in November. A suction-cup blackout like the Gro Anywhere Blind goes up in minutes and suits a rental where you cannot drill.
Keep the evening warm and dim. Where it now gets dark before dinner, you will have lamps on for hours before bed. It is worth knowing why a warm amber bulb is the one to leave on, and cool white ceiling light is best kept for the daytime.
Change the clocks before bed on Saturday, as NSW also suggests, then run Sunday by the new time from the first minute.
What week one actually looks like
For a fall-back change at a higher latitude, expect a child who is fading hard at 4:30 or 5pm, when the new darkness says night. Then expect an early morning, because the sun is now up an hour earlier by the clock. Resist both. Save the outdoor play for the last hour of daylight rather than the middle of the afternoon, keep dinner at its usual clock time, and hold bedtime within about half an hour of normal. An early bedtime is the fastest route to a 5am start.
For a spring-forward change, the problem runs the other way: bedtime in broad daylight, and a child who is not sleepy yet. Darkness in the room does most of that work.
If you are only weeks into the move, remember that the clock change is sitting on top of a bigger settling-in process. New rooms, new sounds and a new routine are the subject of bedtime after moving abroad, and those take weeks rather than nights. A bad week around the time change is usually both at once, not a sign that something new has gone wrong.
FAQ
Should we shift gradually or switch all at once?
Either works, and Betteroo’s guide lays out both. After a move I lean gradual, because everything else in the child’s life has already changed at once, and a 15-minute step is the smallest change you can make.
My toddler is exhausted at 4:30pm since the clocks went back. Should I let them sleep?
Not if you can help it. A nap that late, or a bedtime pulled an hour early, moves the whole body clock towards a pre-dawn wake-up. Go outside in the last of the daylight, keep the lamps on and warm, and aim for bedtime within half an hour of normal. The approach is the same one that works for evening drowsiness in toddler jet lag.
How long before sleep settles?
For the clock change itself, usually several days to about a week. At a high latitude, the evenings keep darkening for weeks afterwards. That is a season to plan the afternoons around, not a sleep problem to fix.
