Flight Time Calculator
Estimate flight duration and arrival time from departure time, time zone difference and flight length.
Your results
Calculation breakdown
- Arrival time
- (Departure hour + Flight hours + Time zone difference) mod 24
Worked example
A flight departing at 22:00 for 9 hours to a destination 3 hours ahead arrives at approximately 10:00 local time, one day later.
Assumptions
- Does not account for daylight saving changes on the travel date.
- Ignores layover time for direct flight calculations — repeat for each connecting leg.
How this calculator works
Enter your departure time, the flight duration and the time zone difference between departure and destination to estimate your local arrival time. This is useful for planning connections, pickups and jet lag recovery.
Frequently asked questions
How do I find the time zone difference?
Compare the UTC offset of your departure and destination cities; many will differ by whole or half hours depending on daylight saving.
Does this account for daylight saving changes mid-flight?
No, enter the time zone difference that applies on your specific travel date, as it can shift during the year.
Can I use this for connecting flights?
Run it once per leg using each flight's own departure time and duration, then add layover time separately.
