It shows the current time for countries around the world (plus major cities in multi-timezone countries). You can search, pin the places you care about, and those pins are saved in your browser.
How do I pin timezones?
Use the search box or scroll the world list, then click Pin. Pinned places appear under My timezones with large clocks. Click × on a card (or Pin again) to remove it.
Where are my pins stored?
Only in this browser’s localStorage. Nothing is uploaded. Clearing site data or using another browser/device starts fresh.
Are the times accurate?
Yes — times use your browser’s IANA timezone database via Intl.DateTimeFormat, including daylight saving where applicable. Keep your device clock correct.
Why is there only one row for some countries?
Most countries use a single main zone (shown as the capital/primary city). Large multi-zone countries (US, Canada, Australia, Russia, etc.) also list extra cities you can pin separately.
