Flight Time Calculator
When you fly across time zones, the arrival time on your ticket can be confusing. You leave Delhi at 8 in the morning, fly for five hours, and land in Dubai at 11:30 — not 1 in the afternoon. This flight time calculator does that maths for you. Pick your departure and arrival cities, enter when you leave and how long the flight takes, and it shows the local time you land, the day you land on, and the same journey in UTC.
How to use this tool
- Choose your departure city and your arrival city from the two lists. There are more than 20 major cities, each with its standard UTC offset.
- If your city is not listed, switch to "Enter UTC offsets myself" and pick the two offsets directly.
- Enter the departure date and the local departure time, exactly as printed on your ticket.
- Enter the flight time in hours and minutes — the flying time the airline quotes, not counting check-in or layovers.
- Read the result: the big time is your local landing time, and the line below gives the landing date, any day change, and the journey in UTC.
Common routes at a glance
| Route | Time difference | Typical flight time |
|---|---|---|
| Delhi → Dubai | Dubai is 1 hour 30 minutes behind Delhi | About 3 hours 30 minutes to 5 hours |
| Delhi → London | London is 5 hours 30 minutes behind Delhi | About 8 hours 30 minutes to 9 hours 30 minutes |
| Delhi → Singapore | Singapore is 2 hours 30 minutes ahead of Delhi | About 5 hours 30 minutes |
| Dubai → New York | New York is 9 hours behind Dubai | About 13 hours 30 minutes to 14 hours |
| London → New York | New York is 5 hours behind London | About 7 hours to 8 hours |
| Mumbai → Bangkok | Bangkok is 1 hour 30 minutes ahead of Mumbai | About 4 hours to 4 hours 30 minutes |
Flight times in the table are typical ranges for direct flights and change with the aircraft, the route, and the wind. The time differences use standard time offsets, which is what this calculator uses too.
How it works
Every place on Earth keeps its clock at an offset from UTC, the world time standard. Delhi is UTC+5:30, which means Delhi clocks run five and a half hours ahead of UTC. Dubai is UTC+4, London is UTC+0 in winter, and New York is UTC−5 in winter. A flight time calculation is really three steps: turn the departure time into UTC, add the flying time, then turn the result into the arrival city's local time.
Because the offsets are subtracted and added in minutes, places with half-hour offsets like India (+5:30) and Iran (+3:30) work exactly, with no rounding. The calculator also counts whole days. It compares the arrival date with the departure date, so if you land after midnight you see "+1 day", and if you cross the International Date Line flying east you can even land on the day before you left.
One honest warning: the offsets in this tool are standard time offsets. Many countries move their clocks forward one hour in summer — daylight saving time (DST). London in July is really UTC+1, and New York in July is UTC−4. If your flight is in the other city's summer, the real landing time can shift by an hour compared with this standard-time result. Your airline ticket always shows the correct local arrival time, so use this tool for planning and the ticket for the final word.
Worked example
Imran is flying from Delhi to Dubai. His ticket says the flight leaves Delhi at 08:00 and the flying time is 5 hours.
Step 1: Turn the departure into UTC — 08:00 in Delhi (UTC+5:30) is 08:00 − 5:30 = 02:30 UTC.
Step 2: Add the flight time — 02:30 + 5 hours = 07:30 UTC.
Step 3: Turn UTC into Dubai time — 07:30 + 4 hours (UTC+4) = 11:30 in Dubai.
Step 4: Check the day — 11:30 is on the same calendar day, so there is no day change.
So Imran lands at 11:30 Dubai time, even though five hours of flying have passed. The clock only moved forward three and a half hours because Dubai is an hour and a half behind Delhi. That is exactly the result the calculator gives for Delhi at 08:00 with a 5-hour flight.
FAQ
What time will I land if I fly from Delhi to Dubai?
It depends on your departure time and flight length. For example, leaving Delhi at 08:00 with a 5-hour flight, you land in Dubai at 11:30 local time the same day, because Dubai is 1 hour 30 minutes behind Delhi.
Why is my arrival time earlier than I expected?
When you fly west, you cross into earlier time zones, so the clock moves back while you fly. A 5-hour flight from Delhi to Dubai advances the local clock by only 3 hours 30 minutes, because Dubai is 1 hour 30 minutes behind Delhi.
Does this calculator handle daylight saving time?
It uses standard time offsets for every city, and it says so on the page. In summer, cities like London and New York move one hour forward, so a real landing time can differ by one hour. Your ticket always shows the correct local arrival time.
What does +1 day mean on a flight?
It means you land on the calendar day after the day you left. This is common on long flights east or on late-night departures. For example, leaving Delhi at 23:30 for New York, you land the next day by the calendar, even though the flight is about 14 to 15 hours.
Can a flight land before it takes off?
By the local clock, yes. Flying east across the International Date Line, for example from Auckland to Los Angeles, you can land on the morning of the same day you left in the evening. The flight time is still positive — only the clock and the calendar move back.
What is UTC and why does the result show it?
UTC is the world time standard that all time zones are measured from. Pilots and airlines plan in UTC because it never changes. This calculator shows the UTC departure and arrival times so you can see the journey with the time zones stripped away.
Note: offsets are standard time. Daylight saving time can shift a real arrival by one hour, and your airline ticket is always the final word on landing time.
