About the Flight Arrival Time Calculator
Enter where and when your flight leaves, the flight time and where it lands: the calculator shows the local arrival time, whether that is the next day (+1) or even the day before (−1), how far the clocks differ, and what time it will be back home when you land. Add connections with their layovers to see the whole trip, step by step.
The second mode works the other way round: from the local departure and arrival times on a ticket it works out the real flight time. Time zones come from the time-zone database built into your browser, so daylight-saving time is right for the date you travel — even when the clocks change during the flight. Type an airport code such as DEL, LHR or JFK, or any city.
How to use it
- Choose Arrival time to find when you land, or Flight time to find how long a flight takes.
- Pick the departure airport or city — type a code like
BOMor a name likeMumbai— and enter the local date and time of departure. - For the arrival time: enter the flight time in hours and minutes and the destination. For a trip with stops, press Add a connection and enter the layover and the next flight.
- For the flight time: enter the destination and the local arrival date and time.
- Read the arrival time, the timeline and the time back home. Copy copies the itinerary; Add to calendar saves it as an .ics event.
Examples
DEL, Tue 6 Oct 2026 at 10:00, 9 h 30 min to LHR
15:00 the same day in London (BST); London is 4 h 30 min behind Delhi
JFK, 6 Oct 2026 at 22:00, 7 h to LHR
10:00 on 7 Oct in London (+1)
AKL, 6 Oct 2026 at 08:00, 8 h 40 min to HNL
17:40 on 5 Oct in Honolulu (−1) — you land the day before you left
DEL 04:00 → 3 h 30 min to DXB → 2 h 15 min layover → 7 h 45 min to LHR
Dubai 06:00, leave 08:15, London 13:00 the same day; 13 h 30 min in total
Leave BOM 01:30 on 6 Oct, land SFO 05:00 on 6 Oct (local times)
16 h
Common uses
- Telling the people picking you up when you really land, in their time.
- Booking a hotel, a taxi or a train after a long-haul flight.
- Checking whether a connection leaves enough time on the ground.
- Working out how long a flight is when the ticket only shows local times.
Why the arrival date can be +1 or −1
A ticket shows local times at each airport, so the date can change even on a short flight. Flying east you move the clock forward: leave New York at 22:00 and you land in London at 10:00 the next morning after seven hours. Flying west you gain hours: crossing the International Date Line from New Zealand to Hawaii, you land at 17:40 on the previous calendar day although you flew 8 h 40 min. +1 and −1 compare the local date of arrival with the local date of departure.
Daylight-saving time
Each place keeps its own daylight-saving rules, applied for your exact date. If the clocks change while you are travelling, the calculator says so: leave London at 00:30 on Sunday 25 October 2026 and the UK clocks go back an hour during the flight, so a flight from 00:30 to 08:30 London time lasts 9 hours, not 8. A departure time that does not exist (the hour skipped when clocks go forward) is moved to the time it becomes; a time that happens twice uses the first one, and the page says so.
Where the times come from
Time zones come from the IANA time-zone database built into your browser. About 200 major airports can be found by their three-letter IATA code; any other place can be found by city, country or time-zone name. Nothing is looked up online: the calculation uses only the times you enter, and works offline.
Limitations
- It does not look up flight schedules, delays or real flight times — it calculates from the times you enter. Airline schedule times are gate to gate and the actual time varies with wind and delays.
- Only major airports have a code here; for others, search for the city or the time zone.
- Time-zone rules are those of your browser’s database. A rule that a government changed very recently may only appear after a browser update.

Frequently asked questions
How do I calculate the arrival time of a flight?
Add the flight time to the departure time to get the moment of landing, then read that moment on the clock of the destination. The calculator does both steps with the exact time-zone rules for that date.
What does +1 mean on a flight ticket?
That the flight lands on the next calendar day, in the local time of the destination. −1 means it lands on the previous calendar day, which happens when you fly east to west across the International Date Line.
Why does my flight seem to arrive before it leaves?
Because the arrival is shown on the clock of a place that is many hours behind. Leave Tokyo at 21:00 and fly seven hours to Honolulu, and you land at 09:00 on the same date — an earlier clock time than you left. The real time in the air is shown separately.
Does it handle daylight-saving time?
Yes. The rules of each place are applied for the date of travel, and if a place’s clocks change during the trip the result mentions it.
Can I add stops?
Yes. Add a connection adds a layover and another flight (up to three connections). The timeline shows the local arrival and departure times at each airport.
