About the Time Zone Converter

This converter shows one moment in many time zones at once: the local time, the date (with a "+1 day" hint when it falls on another day), the UTC offset, the abbreviation such as CEST or EDT, and whether daylight saving time is in effect. It uses your browser's own time zone database through Intl.DateTimeFormat, so it knows every IANA zone and its current rules.

The meeting planner below the table lays out the 24 hours of the chosen day in every zone, with working hours (9:00 to 17:00) highlighted, so you can spot an hour that suits everyone.

How to use it

  1. Pick a date, a time and the time zone you're starting from, or press Now to follow the current time live.
  2. Add zones by IANA name (Asia/Singapore) or city (Paris), and remove the ones you don't need. Your list is saved in this browser.
  3. Click an hour in the planner to move the meeting to it, then copy the table as text.

Common questions

What happens on daylight saving changes?

When clocks spring forward, an hour of wall time doesn't exist. The converter moves it forward by the size of the gap (2:30 becomes 3:30 EDT), as most calendar apps do, and says so. When clocks fall back, an hour happens twice; the first one is shown and you can switch to the second.

Why does the abbreviation sometimes show nothing?

Many zones have no widely used abbreviation in your browser's data, so only the UTC offset is shown. Offsets are unambiguous; abbreviations like IST or CST are not.
