# Jet Lag With Kids > Free family jet lag calculator. Enter two cities and kids' ages to get a day-by-day jet lag plan with bedtimes for each age, light timing, naps, in-flight sleep and optional melatonin guidance. Built on published circadian research (CDC Yellow Book; Eastman & Burgess). Not medical advice. Last reviewed 2026-11-09. Key facts: - Jet lag lasts about 1 day per time zone after flying east and a little less after flying west. - Shifting bedtimes 2–3 days before the trip (adults 1 h/day, kids 15–30 min/day) cuts 1–2 days. - Light timing is the main lever; the calculator estimates each person's body-temperature low point (about 2.5 h before usual wake time) to set light windows. - For 10+ hours east, the plan delays the clock the long way around. - Melatonin: adults optional (0.5–3 mg at local bedtime after flying east); children only with a pediatrician's OK; not for babies or toddlers. - Plans can be linked with URL parameters, e.g. https://jetlagwithkids.com/?f=Denver&t=London&a=2&k=3,8&p=2 ## Main pages - [Family jet lag calculator](https://jetlagwithkids.com/): Free day-by-day jet lag plan for families. - [Family jet lag plans by route](https://jetlagwithkids.com/jet-lag/): Ready-made plans for 66 routes. - [Jet Lag With a Baby: Day-by-Day Plan for Infants](https://jetlagwithkids.com/jet-lag/with-a-baby/): Babies often settle into a new time zone within a few days, because feeds and daylight are strong time cues. Shift their schedule 15 minutes a day before you go, feed during takeoff and landing, move feeds and naps to local time on arrival, and get them outside in daylight during the day. - [Jet Lag With a Toddler: Naps, Bedtime and Early Wakes](https://jetlagwithkids.com/jet-lag/with-a-toddler/): Toddlers usually need several days to adjust to a big time change, often 3–6. Shift bedtime 15 minutes a day before the trip, keep their naps but move them to local time, end the last nap by about 4 PM, and get lots of outdoor play in the morning or afternoon depending on direction. - [Jet Lag With Kids (Ages 4–8): Family Plan That Works](https://jetlagwithkids.com/jet-lag/with-young-kids/): Kids aged 4–8 usually take about as long as adults to adjust, often 3–6 days after a big time change. Shift bedtime 30 minutes a day before the trip, sleep on the plane only during destination night, allow one nap of up to 45 minutes before 2 PM on arrival day, and keep them outdoors during the right light windows. - [Jet Lag With Teens: Light, Phones and Sleep-In Rules](https://jetlagwithkids.com/jet-lag/with-teens/): Teens take about as long as adults to adjust (roughly one day per time zone east, less going west), but eastward trips are hardest for them because their body clocks naturally run late. Get them into bright morning light, cap naps at 30 minutes, and keep phones out of bed. - [How Long Does Jet Lag Last for Kids? Days by Time Difference](https://jetlagwithkids.com/jet-lag/how-long-does-jet-lag-last-for-kids/): Kids usually need about one day per time zone to adjust after flying east and a little less after flying west, so a 6–8 hour trip often means 4–8 days. A 2–3 day head start and well-timed daylight can cut 1–2 days. - [Melatonin for Kids and Jet Lag: Safety, Dose and Timing](https://jetlagwithkids.com/jet-lag/melatonin-for-kids/): Kids should only take melatonin for jet lag after talking with their pediatrician. When a doctor approves it for a child aged 4 or older, a low dose (often 0.5–1 mg) 30–90 minutes before the new bedtime for a few nights after flying east is typical. It is not recommended for babies and toddlers. - [Jet Lag Time Difference Chart: Popular Family Routes](https://jetlagwithkids.com/jet-lag/time-difference-chart/): This chart lists the clock difference for popular family routes in July and January, the body-clock shift you will actually feel, and estimated days to adjust with and without a 2-day head start. - [Jet Lag on the Way Home With Kids: Return Trip Plan](https://jetlagwithkids.com/jet-lag/coming-home/): Jet lag on the way home runs in the opposite direction from your outbound trip: after a US–Europe vacation the return west is usually easier, while coming home east from Asia, Australia or Hawaii is usually harder, about one day per time zone. - [Jet Lag Packing Checklist for Kids: The Family Sleep Kit](https://jetlagwithkids.com/jet-lag/packing-checklist/): A family jet lag sleep kit needs four things: tools to make it dark (eye masks, blackout covers), tools to make it bright or block light at the right times (sunglasses, a light box if it is winter), familiar bedtime cues (lovey, pajamas, book, white noise) and snacks and water for destination meal times. - [Kids' Jet Lag Not Getting Better? Fixes for Common Problems](https://jetlagwithkids.com/jet-lag/troubleshooting/): If jet lag isn't improving after a few days, the usual cause is light at the wrong time, sleeping in, or long late naps. Fix those three, hold a fixed wake-up time, and most families see progress within 1–2 days. - [Family jet lag guides](https://jetlagwithkids.com/jet-lag/guides/): Index of guides. - [Jet Lag Gear for Kids: Blackout, White Noise, Plane Sleep & Light](https://jetlagwithkids.com/jet-lag/gear/): The gear that helps most with kids' jet lag controls light and sleep cues: a portable blackout blind or SlumberPod for daytime naps, a travel white noise machine, kids' sunglasses for "avoid light" windows, and familiar sleep gear for the plane. You don't need much: timing your light and bedtimes matters more than anything you buy. - [Best Travel Blackout Options for Kids: Blinds, SlumberPod & Hacks](https://jetlagwithkids.com/jet-lag/gear/travel-blackout/): The best travel blackout option depends on your child's bed: a suction-cup portable blackout blind darkens the whole room, a SlumberPod darkens just a travel crib or play yard, and a breathable stroller shade covers naps on the go. Free hacks (painter's tape plus foil or dark bags, clothespins on curtains) work surprisingly well for one trip. - [Best White Noise Machines for Travel With Kids (and Safe Volume)](https://jetlagwithkids.com/jet-lag/gear/white-noise-for-travel/): A small rechargeable white noise machine helps kids sleep in unfamiliar, noisy rooms and keeps the same sleep cue from home. Pick one that runs on battery for the plane and stroller, place it away from the crib, and keep the volume low. A 2014 Pediatrics study found infant sleep machines can exceed recommended noise limits at maximum volume. - [Travel Insurance for Families: What to Check and Where to Compare](https://jetlagwithkids.com/jet-lag/travel-insurance-for-families/): Family travel insurance is most worth it for expensive, nonrefundable trips and for travel abroad, where US health plans may cover little or nothing. Compare "comprehensive" plans that bundle trip cancellation, travel medical and medical evacuation, check how they price children, and use a comparison site such as Squaremouth or InsureMyTrip to see plans side by side. - [Affiliate disclosure](https://jetlagwithkids.com/affiliate-disclosure/): How affiliate links work on this site. - [How the calculator works](https://jetlagwithkids.com/how-it-works/): Methodology, limits, privacy and sources. ## Route plans - [Jet lag New York to London with kids](https://jetlagwithkids.com/jet-lag/new-york-to-london-with-kids/): London is 5 hours ahead of New York most of the year.
