World Clock

Track major global business cities in an electronic clock layout, keep daylight saving time and standard time correct automatically, and show only the cities you care about.

Times are rendered from IANA time zones in your browser, so daylight saving time and standard time stay accurate automatically.

DST-Safe by Design

This tool uses IANA time zones instead of hardcoded offsets. That keeps seasonal changes correct for cities like New York, London, and Sydney without manual updates.

Saved in This Browser

The first view starts with a curated default set. After that, your visible city choices are stored locally so the page can restore them on your next visit.

FAQ

What are daylight saving time and standard time?

Daylight saving time usually means moving the clock forward by one hour during part of the year to keep more evening daylight. Standard time is the regular local time used after that seasonal shift ends. Not every city uses it, and transition dates differ by region.

Does this world clock handle daylight saving time correctly?

Yes. It formats each clock with its IANA time zone, so cities that switch between daylight saving time and standard time are shown correctly as your browser updates the time.

Can I choose which cities stay visible?

Yes. The page starts with a small core set of global business cities, and you can show or hide the rest of the preset list at any time.

Are my selected cities saved to the server?

No. Your selection is stored only in this browser so the tool can remember the cities you want to keep visible.
