Why 7:00 becomes 6:00 after fall back
Your child’s body clock doesn’t know the clocks changed. The morning after fall back, a baby who always wakes at 7:00 wakes when the clock says 6:00. Spring forward runs the other way: 7:00 a.m. feels like 6:00, and a 7:00 p.m. bedtime comes an hour before your child is tired.
The planner moves every part of the day together, so the gaps between naps, feeds and bedtime stay the same. Days before the change use the old clock, and days from the first morning after it use the new one.
Light helps as much as the schedule
Light is the strongest signal for the body clock. Morning light moves it earlier, evening light pushes it later, and young children are especially sensitive to light in the evening. After fall back, keep early mornings dark and get outside in the late afternoon. After spring forward, open the curtains soon after waking and use blackout blinds for bright evenings.
How big should each step be?
No trials have compared step sizes for babies. These are common practice among children’s sleep advisers, not rules.
| Age | Usual approach |
|---|---|
| Under 4 months | No special plan; switch clocks and follow feeding cues |
| 4–12 months | 10–15 minutes a day for 4–6 days |
| 1–3 years | 15–20 minutes a day, or split the difference |
| 3 years and up | 30-minute steps, or split the difference |
Example: spring forward on March 14, 2027
A 10-month-old wakes at 7:00 a.m., naps at 9:30 and 1:30, and goes to bed at 7:00 p.m. With 15-minute steps before the change, the plan starts on Wednesday:
| Date | Wake-up | Nap 1 | Nap 2 | Bedtime |
|---|---|---|---|---|
| Tue, Mar 9 | 7:00 | 9:30 | 1:30 | 7:00 |
| Wed, Mar 10 | 6:45 | 9:15 | 1:15 | 6:45 |
| Thu, Mar 11 | 6:30 | 9:00 | 1:00 | 6:30 |
| Fri, Mar 12 | 6:15 | 8:45 | 12:45 | 6:15 |
| Sat, Mar 13 | 6:00 | 8:30 | 12:30 | 6:00 |
| Sun, Mar 14 (new clock) | 7:00 | 9:30 | 1:30 | 7:00 |
Overnight on Saturday the clocks jump from 2:00 to 3:00, so Sunday’s 7:00 wake-up is what the baby’s body expects. Open this example in the planner.
When the clocks change in the US, UK, Europe, Australia and New Zealand
In the US and most of Canada, clocks go forward on the second Sunday in March and back on the first Sunday in November, at 2:00 a.m. Hawaii, most of Arizona and most of Saskatchewan don’t change. The UK and EU change on the last Sunday in March and October. In New South Wales, Victoria, the ACT, Tasmania and South Australia, clocks go forward on the first Sunday in October and back on the first Sunday in April; Queensland, Western Australia and the Northern Territory don’t change. New Zealand goes forward on the last Sunday in September and back on the first Sunday in April. Most of Asia and Africa, and Mexico since 2022, don’t change their clocks.
| Region | 2026 | 2027 |
|---|---|---|
| US and Canada | Forward Mar 8, back Nov 1 | Forward Mar 14, back Nov 7 |
| UK and EU | Forward Mar 29, back Oct 25 | Forward Mar 28, back Oct 31 |
| NSW, VIC, ACT, TAS, SA | Back Apr 5, forward Oct 4 | Back Apr 4, forward Oct 3 |
| New Zealand | Back Apr 5, forward Sep 27 | Back Apr 4, forward Sep 26 |

Questions parents ask
How do I adjust my baby’s schedule for daylight saving time?
Move the whole day (wake-up, naps, feeds and bedtime) in small steps, usually 10 to 15 minutes a day, until it sits where you want it on the new clock. You can do the steps before the change, after it, or meet in the middle. The planner above gives the exact times for each date.
Should I start before or after the time change?
Both work. Starting 4 to 6 days before means the new clock fits on day one, which suits babies who find change hard. Starting after is simpler because nothing changes until the clocks do. No research shows one is better for babies, so pick the one you will stick to.
My baby already wakes at 6 a.m. What happens when the clocks fall back?
Without a plan, a 6:00 wake-up becomes 5:00 on the new clock. Shift the day later before the change (for example 15 minutes a day for 4 days), keep the room dark until your target wake-up, and get bright light in the late afternoon.
What if my baby won’t fall asleep at the new bedtime after spring forward?
A 7:00 p.m. bedtime feels like 6:00 p.m. to your child’s body, and it may still be light outside. Move bedtime earlier in small steps, use blackout blinds, dim the lights for the hour before bed, and wake your child at the planned time in the morning.
How long does it take a baby to adjust to the time change?
Most families find it takes a few days to a week. A plan with 15-minute steps takes four days for a one-hour change. There is little research on babies specifically, so treat any timeline as a rough guide.
Do newborns need a daylight saving plan?
Usually not. Day and night rhythms develop over the first few months, and young babies feed and sleep around the clock. Most parents switch to the new clock and follow feeding cues. Never delay a feed to stick to a schedule.
What should I do with naps and feeds?
Move nap start times and feeds by the same step as wake-up and bedtime, and keep nap lengths the same. If a nap falls apart, a short catnap or a slightly earlier bedtime is fine. Babies who feed on demand should keep doing so.
Can I use the clock change to get a later wake-up?
Yes. Spring forward turns a 5:30 wake-up into 6:30 if you do nothing. Fall back turns an 8:00 wake-up into 7:00, which helps late sleepers. Open “Change plan options” in the planner and choose the target you want.
