World Clock
Track the current time across multiple cities and time zones at a glance — add any city, switch between 12- and 24-hour formats, and see day/night and date offsets. Your selection is remembered on this device.
Add the cities you care about and watch their clocks tick in real time, side by side. Each card shows the local time, the weekday and date, the UTC offset, and a sun or moon to tell day from night at a glance; when a city has already rolled into the next calendar day (or is still on the previous one) a +1 / −1 badge makes it obvious.
- 50+ cities — search by city, country, or time-zone name and add as many clocks as you like.
- 12- or 24-hour — switch formats with one tap; optionally show seconds.
- Day & night — a sun/moon marker and date offset keep distant zones unambiguous.
- Remembered — your chosen cities and preferences are saved in this browser.
Everything runs locally in your browser using your device’s built-in time-zone data — nothing is sent to a server.
