World Clock
About the World Time Studio
Track the current time across multiple cities at once, with each card showing the local time, the offset from your own time zone, a day/night indicator, a working-hours status, and live local weather. Add or remove cities from a searchable list; your selection is saved in your browser so it’s there next time.
City weather is loaded from a free public weather service, so that part needs an internet connection.
How to use it
- Your local time appears first, alongside a few default world cities.
- Click Add City and search to add more locations.
- Read each card for the local time, the +/- hour offset, and whether it’s working hours there.
Frequently asked questions
How is each city’s time calculated?
Times are derived from your device clock and each city’s IANA time zone using the browser’s internationalisation engine, so daylight-saving changes are handled automatically.
Where does the weather come from?
Live current-weather readings come from the free Open-Meteo public API and refresh periodically. If you’re offline the time still works; only the weather badge is affected.
Are my chosen cities remembered?
Yes. Your list of cities is saved in your browser’s local storage on this device.
