One glance across every timezone you care about

Remote teams, overseas family, client calls, market opens — modern life runs across timezones. This clock shows them all at once, ticking live to the second, with each city's date (spot the "it's already tomorrow there" cases instantly) and the exact offset from your local time. Daylight-saving changes are handled automatically by your browser's IANA timezone database — the same data your operating system trusts. Your city list is remembered on your device for next time.

FAQ

Is daylight saving handled correctly?

Yes — times come from the IANA timezone database built into your browser, which tracks every region's DST rules. London automatically shows GMT in winter and BST in summer.

Will my city list be saved?

Yes — it's stored locally on your device (never on a server) and restored on your next visit.

What does "+6h vs you" mean?

That city's clock is 6 hours ahead of your local time right now — handy for scheduling calls. Use our Timezone Converter to convert a specific meeting time.
