Flight Time Calculator
Find your flight's arrival time: enter departure time, departure and arrival time zones, and flight duration.
Crossing time zones and not sure when you'll land? Enter your departure date, local departure time, both time zones, and the flight duration to get your arrival time in the destination's local time — with daylight saving handled automatically.
How to use this calculator
- Enter your departure date and local departure time.
- Choose the departure and arrival time zones from the list.
- Enter the flight duration in hours and minutes (use the airline's published time).
- Press Calculate to see your arrival in the destination's local time.
The formula
Arrival (UTC) = departure local − departure offset + duration; then convert to arrival zone
Worked example
Departing New York at 10:00 AM on a 7-hour flight: 10 AM EDT is 2 PM UTC, plus 7 hours is 9 PM UTC, which is 10:00 PM in London (BST).
Frequently Asked Questions
Why is flight arrival time confusing across time zones?
Because the clock changes beneath you. A 7-hour flight leaving New York at 10 AM doesn't land at 5 PM — London is 5 hours ahead, so it's 10 PM local time on arrival. Airlines print both times on your ticket, but when planning connections, pickups, or hotel check-ins, you need the destination's local time, which this calculator gives you.
Does this handle daylight saving time?
Yes. The calculator uses the official IANA time zone database, so it applies the correct UTC offset for your exact travel date — including daylight saving transitions. Just make sure the departure date is right, since offsets change with the seasons.
What about layovers?
Calculate each flight segment separately: the arrival time of the first leg becomes the departure time of the next. Leave generous connection time — at least 60–90 minutes domestic and 2–3 hours international — since this tool computes scheduled times, not delays.
Why does my flight time differ from the schedule sometimes?
Scheduled flight times include taxi, takeoff queues, and padding for headwinds — the 'block time' from gate to gate, not wheels-up to wheels-down. A New York to London flight is about 6.5–7 hours in the air eastbound but the schedule may say 7–7.5 hours. Enter the airline's published duration for the most useful arrival estimate.
