World Clock & Time Zone Converter

About this converter

Type a time and a place the way you would say it: 8am Tokyo in London, 3pm EST to IST, an airport code such as LHR, or an offset such as UTC+5:30. Every city you add gets a row of hours, lined up so one column is one moment. Drag the slider or tap an hour to move every clock together; green hours are inside everyone's working day, so the meeting time that suits all of them stands out.

Daylight saving is handled for each place on its own dates, so the gap between New York and London is right in the weeks when only one of them has changed its clocks. Pick a date to plan ahead; sunrise, sunset, the next clock change and public holidays for each city sit one tap away. When the time is set, send it as a link, add it to Google Calendar or Outlook, or download an .ics file. It all runs in your browser: no account, no sign-up, and nothing you type is sent anywhere.
