Add duration and time-zone difference
The tool adds flight duration to departure time and then applies the destination offset relative to origin.
Estimate destination date and time before comparing real schedules.
This is a simple offset calculation and does not automatically apply daylight saving or airline schedules.
The tool adds flight duration to departure time and then applies the destination offset relative to origin.
Crossing midnight moves the destination date forward or backward along with the calculated time.
Use -9 when the destination is nine hours behind the origin and +1 when it is one hour ahead.
Seasonal DST, routing, and schedule padding can differ, so the airline itinerary remains authoritative.
Enter both hours and minutes for a more useful short- or long-haul estimate.
