Flight Duration Calculator
Enter departure and arrival local times with their cities. The duration accounts for both time zones, daylight saving and the date line. Uses the same city list as the Time Zone Converter.
Frequently asked questions
Why can the arrival clock look earlier than departure?
Flying east across the date line, or west across many zones, the local clock at the destination can show an earlier time or date. The duration uses absolute time, so it is still correct.
Does it handle daylight saving?
Yes. Each local time is read in its own zone on that date, so a summer or winter clock change is included.
My city is missing. What do I do?
Pick a city in the same time zone. The list matches the Time Zone Converter.
