Flight Time Calculator
Work out how long a flight will actually take, from wheels-up to touchdown, based on the departure and arrival date, time, and time zone you enter. The calculator converts both ends of the trip to UTC before comparing them, so overnight flights, daylight saving changes, and trips across the International Date Line all come out correct, without you having to subtract clock times by hand.

Note: This calculator estimates flight duration from the departure and arrival times entered by the user. Actual flight times may vary due to routing, weather, air traffic, aircraft type, and operational conditions.
Frequently asked questions
What is a Flight Time Calculator?
A Flight Time Calculator is a tool that estimates how long a flight will take by comparing the departure and arrival date, time, and time zone you enter.
How is flight time calculated?
The calculator converts both the departure and arrival date and time into UTC using the selected time zones, then finds the difference between the two UTC timestamps. It never subtracts the displayed clock times directly.
Does the calculator account for different time zones?
Yes. You choose an IANA time zone for the departure and arrival locations, and the tool converts both times to UTC before comparing them, so the correct UTC offset for each location is always used.
Can I calculate flights that arrive the next day?
Yes. Choose an arrival date that is one or more days after the departure date and the calculator will handle the overnight flight and calendar date change automatically.
Does the calculator account for daylight saving time?
Yes. Offsets are calculated for the specific dates you enter, so a daylight saving time change at either location is reflected correctly in the result.
Can I calculate flight time between two airports?
Yes. Use the airport search to pick a departure and arrival airport and the time zone fields fill in automatically. You can also type a city or airport code manually.
Is flight time the same as the actual time spent in the air?
Not exactly. This estimate reflects the departure and arrival times you enter, which can include taxiing, so actual airborne time may differ slightly. Real-world durations also vary with routing, weather, and air traffic.
