Time Zone Converter

Set the date and time and the "from" time zone at the top, then read the matching time in every zone you add below. Add zones with the quick-add buttons or by typing a city into a row, and remove the ones you do not need. The whole table updates instantly, so it works as a meeting planner: enter one moment and see it everywhere at once.

Yes. Each conversion uses the official IANA time-zone rules built into your browser, so daylight saving transitions and historical offset changes are applied automatically. That is why a zone might show UTC-5 in winter and UTC-4 in summer — the converter always uses the correct offset for the exact date you pick, including half-hour and 45-minute zones like India and Nepal.

Because time zones can be many hours apart, the same moment can fall on a different calendar day depending on where you are. A "+1 day" badge means that, for the time you entered, it is already the next day in that zone, while "-1 day" means it is still the previous day there. It is the quickest way to avoid scheduling a call on the wrong date.

Every IANA time zone your browser knows — hundreds of them, covering all countries and regions, including special offsets like UTC+05:30 (India), UTC+05:45 (Nepal) and UTC+12:45 (Chatham Islands). Start typing a city or region name into any zone field and pick from the autocomplete list.

Yes to both. Newly added zones appear at the top of the list, and you can drag the handle on the left of any row to rearrange them — or focus the handle and use the up and down arrow keys. As soon as you add, remove, edit or reorder a zone, your list and its order are saved in your browser, so the next time you open the converter your zones are exactly where you left them.

Yes. The converter runs entirely in your browser using its built-in time-zone database and your system clock — nothing you enter is sent to or stored on any server, and it keeps working offline once the page has loaded.
