Time Zones & World Clock

See the current time in many cities at a glance, and convert a meeting time to other time zones. Daylight saving time is handled automatically.

Cities to show

Time by city

City Date Time UTC offset

Time zone rules (including daylight saving) come from the time zone data in your browser. Double-check times around the days clocks change.

Find shared working hours

Enter working hours for each city to see when everyone is working at once, as a 24-hour bar and a list. Daylight saving time is handled by the browser. Nothing you enter is sent to a server.

Cities and working hours (the first row is the base, up to 6)

If the end time is equal to or earlier than the start, the shift is treated as running past midnight (e.g. 22:00–06:00). The bar covers only the first city's day, so a city whose shift crosses midnight may need the next day checked separately.

FAQ

How do I plan a meeting?

Turn off "live", enter the date and time and the time zone it is in (for example Seoul). The same moment is shown for every selected city. "Copy" gives you text to paste.

What do "next day" and "previous day" mean?

The city's calendar date is one day after (or before) the date in the reference time zone.

What if I enter a time that does not exist during daylight saving?

A skipped time in spring (for example 02:30) is treated as the time after the change (03:30). A time that happens twice in autumn uses the first one (still daylight time).
