Step-by-Step Examples
Example 1
NYC to London Overnight
Depart 22:30, 7h flight, +5 time zones.
- 22:30 + 7h flight + 5h TZ = 10:30 next day London
- So a 10:30 PM departure → 10:30 AM arrival
✓ 10:30 AM next day London
Example 2
LA to Tokyo
Depart 11:00, 11.5h flight, +17 time zones.
- 11:00 + 11.5h + 17h = 39.5h = 15:30 next day Tokyo
✓ 15:30 next day Tokyo
Example 3
London to NYC
Depart 10:00, 8h flight, -5 time zones.
- 10:00 + 8h - 5h = 13:00 NYC (same day!)
- You land 3h after departing — thanks to crossing time zones
✓ 13:00 same day NYC

Common Mistakes to Avoid
⚠️
Using airline departure/arrival times without checking time zones
Airline schedules show local times. A 22:00 departure arriving at 10:30 doesn't mean 12.5 hours of flight — it's 7 hours of flight plus 5 hours of time zone gain.
⚠️
Forgetting date change on Pacific crossings
Flying west from North America to Asia crosses the International Date Line. You may land 2 calendar days after departure even on a 12-hour flight.
Frequently Asked Questions
What is jet lag? ▾
Disruption to circadian rhythm from rapid time zone crossing. Worse going east (shortening days) than west (lengthening days). Rule of thumb: one day of adjustment per time zone crossed.
How to minimize jet lag? ▾
Start adjusting sleep schedule 2-3 days before departure. Stay hydrated. Get sunlight at destination's daytime. Avoid alcohol on the flight. Melatonin (1-3mg) at destination's bedtime.
What is the best way to handle long layovers? ▾
Under 4 hours: stay in transit. 4-8 hours: airport lounge or terminal exploration. 8+ hours: consider leaving the airport if visa-free. Many hub cities allow 24-48 hour stopovers with free or cheap accommodation.
