Flight Arrival Time Calculator

Estimate the destination arrival clock from a departure date, elapsed flight duration and destination-minus-departure offset.

How to use Flight Arrival Time Calculator

1. Enter Departure Date & Time, Flight Duration, Destination UTC Offset Minus Departure (hours). 2. A positive offset difference means the destination clock is ahead. Enter the offsets applicable at departure and arrival; the calculator does not look up airports or named zones. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.

Why use this tool?

Estimate the destination arrival clock from a departure date, elapsed flight duration and destination-minus-departure offset. A positive offset difference means the destination clock is ahead. Enter the offsets applicable at departure and arrival; the calculator does not look up airports or named zones.

How the calculation works

Destination arrival clock = departure clock + elapsed flight duration + (destination UTC offset − departure UTC offset). A positive offset difference means the destination clock is ahead. Enter the offsets applicable at departure and arrival; the calculator does not look up airports or named zones. Calendar and clock values are used as entered, independently of the browser time zone. This is a fixed-offset model: named-zone rules, daylight-saving changes, leap seconds and live flight information are not applied automatically. Use offsets valid at the dates concerned. Clock results round the final instant to the nearest second; calendar results stay within years 0100–9999.

Example

Worked example: Departure Date & Time = "2026-10-12T09:00"; Flight Duration = "2 h 30 min"; Destination UTC Offset Minus Departure (hours) = 2. Result: 2026-10-12 13:30:00 (destination clock).

Practical tip

For departure UTC+1 and arrival UTC+3, enter +2 hours; reverse the sign when the destination is behind.
