How do I add a world clock to my website?

Select the cities you want to display, choose 12- or 24-hour format and a theme, then copy the embed code. Paste it into any website, blog or CMS that supports iframes.

How many cities can I show?

You can display up to 8 cities in a single widget. The clock updates every second in each visitor's browser, so no server is involved.

Is the world clock widget free?

Yes, completely free with no sign-up. A small attribution link is shown when enabled — no hidden tracking or data collection.

Does it handle daylight saving time?

Yes. The widget uses the browser's built-in time zone database (Intl.DateTimeFormat), so it automatically handles DST transitions for every city.
