Time Zone Converter — Convert Time Between Any Two Cities

A time zone converter takes a time in one place and tells you the matching local time everywhere else — the everyday problem of scheduling a call, a launch or a flight across regions. Enter the date and time you have in mind, pick the source zone it belongs to, and add the destination cities you care about. The converter shows each one's local time alongside its UTC offset, so there's no mental arithmetic and no risk of being an hour out.

Time zones are trickier than a fixed number of hours apart because of daylight saving time. Many regions shift their clocks forward in spring and back in autumn, and they don't all do it on the same date — so the gap between, say, London and New York changes by an hour for a couple of weeks each year. This tool relies on your browser's built-in time-zone database, which encodes those rules, so the conversion is always based on the correct offset for the date you choose.

You can compare up to five places at once: the source plus four destinations. Use the dropdowns to pick from major world cities, or tap a quick-select chip — New York, London, Dubai, Mumbai, Singapore, Tokyo, Sydney, Los Angeles, Paris or Toronto — to drop it into the next free slot. A "use my local time now" button fills in the current moment in your own zone as a starting point.

Whether you're booking a meeting with colleagues abroad, catching a live stream, coordinating with family overseas or planning travel, the converter removes the guesswork. Everything runs in your browser with no sign-up, so it's instant and private. Try it above, and pair it with the countdown timer or Unix timestamp converter for related time tasks.
