CREATED ON GLOBAL-CLOCK.COM

Built for people who work across time zones

Add any city, country or zone and see every location on one timeline. Instead of working out offsets by hand, drag across a multi-day grid to find the hours everyone is awake for — whether that is EST and PST, or CET, IST and JST at once.

Times follow the IANA time zone database, daylight saving changes included, so a slot three weeks out is the slot people will turn up for. We track 4,449 cities across 418 time zones.

Pick several slots to build a proposal, copy every local time for the invite, or share the view as a link that opens in the reader’s own time zone.

COMMON QUESTIONS

Does it handle daylight saving time?

Yes. Each city keeps its own rules, so a future date shows the offset in force on that date — not today’s.

What counts as working hours?

09:00–18:00 local by default, with 07:00–09:00 and 18:00–20:00 marked as shoulder hours you can use at a push. Change the window in settings and every grid on the site follows.

Can I send this to someone?

Share this view copies a link that reopens the same cities, date and proposed slots in the reader’s own time zone.
