Timezone Converter

Scheduling a call between Karachi and New York, or checking what time a livestream in London actually starts back home, means working out a time difference that also shifts with daylight saving changes throughout the year. This tool converts a specific date and time from one timezone to another automatically, accounting for that.

Why this handles daylight saving correctly

Unlike a fixed "add 5 hours" rule of thumb, this tool uses your browser's built-in timezone database (the same one your phone and computer already use to show the correct local time) to look up the actual UTC offset for both timezones on the specific date you enter — which matters because many regions shift their offset for daylight saving at different times of year, and a fixed-hour formula gets it wrong during those transition periods.

Common scheduling situations this solves

Setting up an international meeting or call and confirming what time it lands at for participants in another country. Checking when a scheduled online event, product launch, or livestream will actually air in your local time. Coordinating a flight arrival or connection time when travel itineraries list times in the departure and arrival airports' own local timezones rather than a single reference time.

Frequently Asked Questions

Does it account for daylight saving time automatically? Yes — because it uses your browser's timezone database rather than a fixed offset, daylight saving transitions for the specific date you choose are automatically factored in for both timezones.

What if my exact city isn't in the list? Choose the closest major city that shares the same timezone as your location — most regions within a country share one or a small number of standard timezones, so a nearby major city will usually give the correct result.

Is my data saved anywhere? No — the conversion happens entirely in your browser using built-in JavaScript timezone functions; nothing is stored or transmitted.
