What does this tool do?
A flight lands at a different local clock time because of both the time in the air and the time-zone change. Enter the departure time in the origin zone and the destination offset to see the arrival shown on the airport board.
The Formula
Local arrival = departure local time + flight duration + time-zone changeFrequently Asked Questions
Why is the arrival clock time not departure plus duration?
The destination clock is set to a different offset. A positive time-zone change means the destination is ahead, so the local arrival reads later than the elapsed flight time.
Which offset should I enter?
Enter the difference between the destination and origin zones. For a flight from London to Singapore, enter +8; for Singapore to London, enter −8.
