How to Build Your Multi-City World Clock Dashboard

Our World Clock opens pre-loaded with four major time hubs—London, New York, Tokyo, and Cairo—and updates every second using your browser's native Intl.DateTimeFormat IANA time zone database. Each card displays the live 12-hour clock with seconds, the local weekday and calendar date, the UTC offset, and the exact hour difference relative to your device.

  • Add Cities by Name or Country: Type any city or country in English or Arabic into the search box and click a result to pin it to your grid.
  • Automatic Local Persistence: Your custom city dashboard is stored in localStorage so your pinned locations remain intact whenever you reopen the page.
  • Zero DST Guesswork: Seasonal Daylight Saving Time transitions in North America, Europe, and Australia are calculated automatically per region.

Frequently Asked Questions (FAQ)
