Converters & time math
Flight arrival calculator
Add a flight duration to a departure time and land on the right local clock. Pick your cities, set the take-off time, and see exactly when — and what day — you arrive.
How to use the flight arrival calculator
Set the departure
Enter the origin city and the scheduled departure in that city's local time, exactly as the ticket shows it.
Enter the flight duration
Use the block time from the itinerary — gate to gate — rather than time in the air, and include layovers if you are calculating a whole journey.
Choose the destination
Pick where you land. The arrival is computed as a real instant and then expressed in the destination's local clock.
Check the arrival date
Long eastbound flights routinely arrive on the following calendar day, and some westbound Pacific crossings arrive before they left in local terms. The date is part of the answer.
Why arrival times look impossible
Airline itineraries quote both departure and arrival in local time at each airport, which makes the printed duration meaningless on its own. A flight leaving Tokyo at 5pm and arriving in Los Angeles at 10am the same day looks like time travel; it is a nine-hour flight against a seventeen-hour offset. Going the other way, a Los Angeles to Tokyo flight loses a day outright.
The correct calculation is to convert the departure to an absolute instant, add the block time, and convert back into the destination's zone. Done that way the arithmetic is unremarkable and the confusing local times fall out naturally.
Two details are worth getting right. Use block time, not flying time: taxiing and holding can add half an hour and airlines quote gate-to-gate. And be careful across daylight-saving boundaries — a flight departing the night the clocks change has a block time that does not match the difference between the printed local times.
For planning purposes, the useful output is usually not the arrival time but what your body will think it is. A red-eye arriving at 7am local after five hours of poor sleep is a very different day from the same arrival after a full night, and knowing the origin-time equivalent helps you decide what to schedule.
When you'd reach for it
Booking connections
Check whether a tight layover survives once the zone change is accounted for.
Arranging an airport pickup
Give whoever is collecting you the correct local arrival date and time.
Planning the day you land
Decide whether a same-day meeting is realistic given the true elapsed journey.
Managing jet lag
Work out the origin-time equivalent of your arrival to plan sleep and light exposure.
Cargo and logistics
Calculate when a shipment actually lands in destination local time.

Questions & answers
- Why doesn't arrival time equal departure plus duration?
- Because the two cities are in different time zones. This tool adds the flight duration to the real departure instant, then shows the result on the destination's local clock — which is why you can 'arrive before you left'.
- Where do I find the flight duration?
- Use the scheduled block time from your airline or booking (gate-to-gate), not the distance-based estimate. Enter it as hours and minutes.
- Does it handle overnight and next-day arrivals?
- Yes. The arrival date is computed alongside the time, so red-eyes and long-haul flights that land the next day are shown correctly.
