How do you beat jet lag from Los Angeles to Singapore, step by step?
- 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.
- Switch to destination time on board: Set devices to Singapore time and eat on its meal schedule.
- Sleep on the plane: Sleep about 2:45 AM–6:30 AM destination time.
- Time your light: Day 2: get bright light 4:30 PM–9:00 PM. The windows move later each day; follow the daily plan.
- Bedtime on local time: Adults around 11:00 PM on night 1, reaching 10:30 PM by day 6. Wake at a fixed time even after a bad night.
- Short, early naps: Adults/older kids ≤ 20–30 min; little ones keep naps but on local time, ending by ~4 PM.
- Melatonin (optional): Usually not needed westward; adults 0.5 mg only for early-morning waking.
- Meals, caffeine, movement: Eat on local time, hydrate, skip alcohol, adults caffeine mornings only, outdoor activity in the light windows.

What's different about Los Angeles → 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.
- You cross the International Date Line, so you land a calendar day later than the clock math suggests. Plan dates carefully; your body only feels a 9-hour shift.
- Singapore does not use daylight saving time, so the gap is 15 or 16 hours depending on whether Los Angeles is on daylight time (mid-March to early November).
- At roughly 19h 45m 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 11:00 AM departure, the flight overlaps night in Singapore. Aim for sleep from about 2:45 AM to 6:30 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.

Frequently asked questions
How many hours ahead is Singapore from Los Angeles?
Singapore is 15 hours ahead of Los Angeles for most of the year (16 hours the rest of the year). Singapore does not use daylight saving time, so the gap is 15 or 16 hours depending on whether Los Angeles is on daylight time (mid-March to early November).
How long does jet lag last flying from Los Angeles to Singapore with kids?
About 6 days without preparation. Shifting bedtimes later for 2 days before you fly (15–30 minutes a day for kids, 1 hour for adults) cuts it to about 5. Kids usually follow a similar timeline when they get outdoor daylight at the right times.
Should kids sleep on the flight from Los Angeles to Singapore?
Yes, on a typical overnight departure. Sleep roughly 2:45 AM–6:30 AM Singapore time, which is night at your destination. Start a mini bedtime routine when the window opens.
What time should kids go to bed the first night in Singapore?
For kids who normally sleep at 7:30 PM: about 11:00 PM for an 8-year-old and 11:00 PM for a 3-year-old on night 1, moving to their usual time over the next 5 days. Adults around 11:00 PM.
Is jet lag worse coming home to Los Angeles?
The trip home is a 9 hours eastward (advance) shift, usually the harder direction. Plan about 9 days to readjust, and run the calculator again for the return flight.
Do you lose a day flying from Los Angeles to Singapore?
On the calendar, yes: crossing the International Date Line moves you a day forward. Your body only experiences a 9-hour shift.
