Flight time and arrival calculator

Use the local schedule times and named time zones to calculate scheduled elapsed flight time or destination-local arrival. The calculator applies date-specific daylight-saving offsets automatically. Your entries stay in this page and are not uploaded or saved.

What this calculator does not know

It does not look up airports or cities, estimate route distance or flight duration, read live schedules, predict delays, include taxi time or decide whether a connection is workable.

Confirm the schedule with the airline or booking provider. Named-zone rules come from the browser runtime and can change when governments revise future clock rules.

Check the inputs

Keep schedule math separate from a flight prediction.

This calculator does not invent a city-to-city flight estimate. It converts the schedule and named time zones you provide, so every assumption remains visible and replaceable.

Comparing routes or sellers after that? Use the flight booking decision checker to compare backtracking, known fees and traveler time.

Only need to translate a local time between cities? The time zone converter applies the named zones' date-specific daylight-saving offsets automatically.

Start with the published schedule

Use the local departure and arrival dates and times from the same current itinerary, including an overnight arrival date when shown.

Choose the named time zones

The calculator applies each location's date-specific clock rules automatically. Confirm that the selected city or IANA zone matches each airport.

Keep airport time separate

Scheduled flight time is not the full journey. Add check-in, security, transfers, immigration and baggage time to the day plan separately.
