Flight Arrival Time Calculator
Estimate local arrival time from a departure time, known flight duration and destination time-zone difference, including overnight and date-line day offsets.
Enter hours from −26 to +26; quarter-hour offsets are supported.

Calculation breakdown
- Arrival time
- Departure time + Flight duration + Time zone difference, wrapped to 24 hours
Worked example
A flight departing at 22:30 for 9 hours 15 minutes to a destination 3 hours ahead arrives at approximately 10:45 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 the local departure time, flight duration and destination-minus-origin time-zone difference to estimate the local arrival time and day offset.
Estimate local flight arrival time
Enter the local departure hour and minute, the flight duration already shown on the itinerary and the destination-minus-origin time-zone difference. The calculator adds those figures and reports an estimated local arrival time and day offset.
This tool does not derive flight duration from two clock times. Daylight-saving rules can change a city's UTC offset, so use the time-zone difference that applies on the actual travel date.
Air time is different from total travel time
The known scheduled duration may include taxi time but excludes the time spent checking in, clearing security, collecting bags or transferring between flights. Add those periods separately when comparing door-to-door itineraries.
Airlines can change schedules and actual flights can be delayed or rerouted. Use the current itinerary for planning and confirm the final times with the airline before travel.
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.
