What time will you land? Enter your departure city, arrival city, and flight duration — get your exact local arrival time with automatic time zone adjustment.
Frequent flyers, travel planners, and anyone booking international flights will find this tool essential. It eliminates the confusion of '7-hour flight from New York at 8 PM — what time is that in London?' by computing the exact local arrival time, accounting for time zone crossings and Daylight Saving Time transitions automatically.
Enter your departure city, arrival city, departure time (local), and flight duration in hours and minutes. The calculator adds the flight duration to your departure time, then converts the result from UTC into the destination's local time — applying the correct DST offset for the date. The result is the exact local time you will land.
All calculations use the IANA Time Zone Database, which contains verified UTC offsets and historical DST rules for every time zone worldwide. This means the calculator is accurate even for unusual cases like India's UTC+5:30 offset, Nepal's UTC+5:45, or Australia's state-by-state DST boundaries.
Airlines display flight schedules in the departure airport's local time. A flight departing New York at 10:00 PM and arriving 7 hours later is 5:00 AM — but in London, that's 10:00 AM GMT. The 5-hour difference (EST vs GMT) is what this calculator resolves instantly. During summer, when New York observes EDT (UTC-4) and London observes BST (UTC+1), the gap becomes 5 hours — but the calculator handles that automatically.
Sample calculations for common international routes. Actual times vary by date and DST status.

| Mumbai (BOM) → London (LHR) | ~9h | 2:00 AM IST | 6:30 AM GMT |
| Tokyo (NRT) → Los Angeles (LAX) | ~10h | 5:00 PM JST | 10:00 AM PST (same day) |

A typical JFK–LHR flight takes about 7 hours. Departing at 8:00 PM EST (UTC-5), you add 7 hours to get 3:00 AM UTC. London is UTC+0 in winter, so you land at 3:00 AM local time (+1 day). In summer, London is BST (UTC+1), making it 4:00 AM. Always check: your departure time + flight duration + destination UTC offset = local arrival time.
No — you need to input the flight duration yourself. Check your airline's website, booking confirmation, or a flight search engine for the scheduled flight duration. The calculator then converts that duration into a local arrival time at your destination.
It means you will arrive on the following calendar day. This happens when crossing midnight (local destination time) during the flight. For example, departing Los Angeles at 11:00 PM on a 10-hour flight to London means landing at 7:00 PM London time — but on the next calendar day due to the time zone shift.
Yes. Daylight Saving Time is automatically applied for both departure and arrival cities based on the IANA Time Zone Database. If your departure or arrival city observes DST, the calculator uses the correct UTC offset for today's date. You do not need to manually adjust for summer or winter time.
Flying westbound across the International Date Line (roughly 180° longitude, in the Pacific Ocean) typically adds a full calendar day. Flying eastbound removes one. For example, flying from Los Angeles to Tokyo you may land two calendar days after departure even on a 10-hour flight. The calculator handles date-line crossings automatically.
Check your airline booking confirmation, the airline's website, or a flight search engine like Google Flights. The scheduled flight duration is shown as the 'flight time' or 'journey time' in hours and minutes. Note: this is wheels-up to wheels-down time, excluding boarding and taxiing.
Each time zone is roughly 15 degrees of longitude wide and represents 1 hour of offset from UTC. Flying eastbound moves your clock forward; flying westbound moves it back. A New York–London flight crosses approximately 5 time zones, which is why an 8-hour flight departing at 8 PM still lands in London at around 8 AM the next morning — the clock jumped 5 hours forward.
Not directly — it calculates one leg at a time. For a connecting flight, calculate the first leg to get your layover arrival time, then calculate the second leg starting from that arrival time. Make sure to use the layover airport's city for the second calculation.
Enter the scheduled departure time in the departure city's local time — this is the time shown on your boarding pass or booking. Do not adjust for time zones; the calculator handles the conversion automatically.
The most common reasons are: (1) an incorrect flight duration — double-check against your booking; (2) a city being assigned to the wrong time zone — try using the nearest major city in the same zone; (3) DST ambiguity around clock-change dates, where an hour can appear or disappear.
A JFK–LHR flight crosses roughly 5 standard time zones (UTC-5 EST to UTC+0 GMT). During summer, New York uses EDT (UTC-4) and London uses BST (UTC+1), still a 5-hour difference. This is why a ~7-hour overnight flight from New York lands in London in the morning — you gain 5 hours on the clock even though only 7 have passed.
You can enter any hour from 0 to 23 in the departure time selector, which covers the full 24-hour day. Results are displayed in 12-hour AM/PM format. If you need a 24-hour result, simply convert: any time showing PM just add 12 hours (e.g., 3:00 PM = 15:00).
