Time Zone Bedtime Adjuster for Kids
Tell us where you're going, when, and your kid's age — we'll give you a day-by-day bedtime shift schedule so the trip starts smoother and not in jet-lag chaos.
Most kids handle a 2-hour time-zone change badly. Most parents underestimate how much prep helps. The trick is small, consistent shifts in the days before the trip — 15 to 45 minutes per day depending on age — so by the time you land, the body clock is most of the way there. This tool calculates the schedule for you. No accounts, no email, just the dates and target bedtimes.

Frequently asked questions
Why is traveling east harder than west?▼
Traveling east shortens your day — you have to fall asleep when your body still thinks it's mid-afternoon. Traveling west lengthens it — staying awake a bit later is just like a normal kid's bad-bedtime night. The general rule: 1 day to recover per 1 hour east, 1 day per 1.5 hours west. East is roughly 50% harder for kids of all ages.
How early should we start shifting bedtime before a trip?▼
Take the time-zone difference in hours, multiply by 60 minutes, divide by your kid's safe daily shift (15 min for toddlers, 20 for preschool, 30 for school-age, 45 for teens). That tells you the minimum days needed. For a 3-hour east trip with a school-age kid, that's 180 / 30 = 6 days. Less time? Use this calculator to see how close you can get and plan recovery time at the destination.
What if we only have 2-3 days before the trip?▼
Don't try to do the full shift — push as far as you safely can in those days, then plan low-key first 2-3 days at the destination. Pool, beach, slow mornings, and outdoor light are all that's needed. Save big theme-park or sightseeing days for after kids have synced.
Do naps need to shift too?▼
Yes. Naps shift on the same schedule as bedtime — same daily increment, same direction. For a kid who naps once at 1pm and you're traveling east 3 hours, push nap by 30 min/day until it's at 12:30, 12:00, 11:30, 11:00, 10:30. Skipping the nap is worse than a slightly-shifted one.
How do we handle the actual travel day?▼
On travel day, switch to local time the moment you land. Wake the kids up at local morning even if it's 4am body time. Eat meals on local schedule. Get sunlight. Avoid screens after dark local time. Day 1 is rough; day 2 is usually 70% better; day 3 most kids are synced.
Does melatonin help kids adjust to new time zones?▼
Talk to your pediatrician — but in general, melatonin is sometimes used short-term for jet lag in older kids. The American Academy of Pediatrics doesn't recommend routine use under age 3. Light exposure (sunlight in the morning at the destination) is the strongest natural cue and what we'd push first.
