What does a family jet lag plan for New York → Singapore look like?

Sample built by the calculator for 2 adults and kids aged 3 and 8, departing Jul 1 with a 2-day head start. Home bedtimes: adults 10:30 PM, kids 7:30 PM, everyone up at 6:30 AM. Times before the trip are New York time; after arrival, Singapore time.

How do you beat jet lag from New York to Singapore, step by step?

1. Pre-shift at home: For 2 days before you fly, move bedtimes and wake times later each day (adults 60 min, kids 4–8 30 min, babies/toddlers 15 min), with bright light in the evening.
2. Switch to destination time on board: Set devices to Singapore time and eat on its meal schedule.
3. Sleep on the plane: Sleep about 10:30 PM–2:05 AM destination time.
4. Time your light: Day 2: get bright light 1:30 PM–7:30 PM and avoid bright light 7:30 PM–9:00 PM. The windows move later each day; follow the daily plan.
5. Bedtime on local time: Adults around 9:00 PM on night 1, reaching 10:30 PM by day 8. Wake at a fixed time even after a bad night.
6. Short, early naps: Adults/older kids ≤ 20–30 min; little ones keep naps but on local time, ending by ~4 PM.
7. Melatonin (optional): Usually not needed westward; adults 0.5 mg only for early-morning waking.
8. Meals, caffeine, movement: Eat on local time, hydrate, skip alcohol, adults caffeine mornings only, outdoor activity in the light windows.

What's different about New York → Singapore?

• Flying west is the easier direction. Expect early wake-ups (4–5 AM) the first mornings; keep lights dim and treat it as night until the planned wake time.
• At 12 hours east, the body clock usually adjusts faster by moving later (12 hours) than earlier. The plan uses evening light and avoids early-morning light for that reason.
• Singapore does not use daylight saving time, so the gap is 12 or 13 hours depending on whether New York is on daylight time (mid-March to early November).
• At roughly 21h 15m of travel, this is a long-haul day. Pack two "sleep kits" (pajama layer, eye mask, lovey) and plan meals on Singapore time.
• On a typical 5:30 PM departure, the flight overlaps night in Singapore. Aim for sleep from about 10:30 PM to 2:05 AM local time, then land ready for a full day.
• Singapore is near the tropics, so daylight is strong and roughly 6 AM to 6–7 PM year-round. Sunglasses and shade are easy tools when the plan says to avoid light.

What should each age do?

• Babies & toddlers (0–3): keep naps on Singapore clock time and end the last nap by about 4 PM. No melatonin.
• Kids 4–8: one nap of up to 45 minutes before 2 PM on arrival day only if needed, then outdoor play in the light windows.
• Tweens & teens: naps of 20–30 minutes max, devices off an hour before bed.
• Adults: melatonin usually isn't needed going west; caffeine is fine until mid-afternoon to make it to local bedtime.
