Worked examples

Three conversions people run most often, worked through step by step. Load the same cities above to check any other date.

Convert New York time to London

A 9:00 AM Monday call in New York (UTC−04:00 in summer) is 2:00 PM Monday in London (UTC+01:00). Take the source offset away to reach 13:00 UTC, then add the London offset. The same call in January is still 2:00 PM London time, because both cities are on standard time — but for the two weeks between the US and UK clock changes in March it becomes 1:00 PM.

Convert UTC time to a local clock

A product release scheduled for 14:00 UTC lands at 10:00 AM in New York, 3:00 PM in London, 5:00 PM in Helsinki, 7:30 PM in Delhi and 11:00 PM in Tokyo on the same calendar day, and 12:00 AM the next day in Sydney during its summer. Pick UTC as the from city to run this yourself.

Work out the time difference between two cities

Used as a time difference calculator, the result row labelled “Time difference” shows the gap in hours for the exact date you selected — for example +7 hours between New York and Helsinki most of the year, dropping to +6 for a fortnight each spring. The day-shift label tells you whether the destination is on the previous, same or next calendar day.

How the conversion works

Every city on this page is mapped to an official IANA time zone such as America/New_York or Europe/Helsinki. When you enter a date and time, the converter turns that wall-clock moment into a single point on the universal timeline, then renders that same instant in the destination zone. Because the rules for each zone — including historic and future daylight saving transitions — come from the browser's built-in time zone database, the result stays correct on both sides of a clock change.

This matters most in March and October, when Europe and North America shift on different weekends. For a fortnight each spring and autumn the gap between New York and Helsinki is six hours instead of the usual seven. A converter that hard-codes offsets gets that fortnight wrong; one that resolves the offset for the specific date you picked does not.

Getting the most out of it

  • Search by city, country or zone name — typing “sing”, “finland” or “asia” all narrow the list.
  • Swap cities with one tap to check the reverse direction before you send an invite.
  • Switch between 12-hour and 24-hour clocks to match the convention your audience uses.
  • Check the day-shift label before booking evening calls across Asia-Pacific and the Americas.
  • Use the meeting planner to find hours that fall in the working day for both parties.

Frequently asked questions

How does this time zone converter handle daylight saving time?+

Daylight saving is applied automatically. Every conversion is resolved against the official IANA time zone database for the exact date you choose, so if New York is on EDT (UTC−04:00) in July and EST (UTC−05:00) in January, the converter uses the correct offset for that day without you changing anything.

How do I convert time between two cities?+

Search for the city you are converting from, pick the date and time, then search for the destination city. The converted time, its UTC offset, the local date and whether it lands on the previous or next day update instantly as you type — no button to press.

What is a UTC offset?+

A UTC offset is how far a location's clock runs ahead of or behind Coordinated Universal Time, the global reference standard. Helsinki in summer is UTC+03:00, meaning local clocks read three hours later than UTC, while New York in summer is UTC−04:00, four hours earlier. Offsets can change twice a year where daylight saving is observed.

Why is the converted time on a different day?+

Large offsets push conversions across midnight. When it is 9:00 AM Monday in New York it is already 10:00 PM Monday in Tokyo, and a 9:00 PM New York meeting falls on Tuesday morning in Tokyo. The converter labels each result as same day, next day or previous day so you never book a call on the wrong date.

Which cities and time zones are supported?+

You can convert between more than 110 major cities across the Americas, Europe, Africa, the Middle East, Asia and Oceania, plus UTC itself. Each city is mapped to its official IANA zone, so places that share a zone — such as Seattle and Los Angeles — always stay in sync.

How do I convert UTC time to my local time?+

Choose UTC as the from city, enter the UTC date and time, then pick your own city as the destination. The converter adds or subtracts the offset in force on that date, so a 14:00 UTC release lands at 10:00 AM in New York during summer time and 9:00 AM in winter, and at 5:00 PM in Helsinki during summer time.

What is the time difference between New York and London?+

London runs five hours ahead of New York for most of the year: 9:00 AM in New York is 2:00 PM in London. The gap narrows to four hours for about two weeks each March and widens back for a week each autumn, because the two countries change their clocks on different weekends. Using this international time converter with a specific date always returns the difference that actually applies that day.
