The Multiple Time Zone Clocks tool lets you view and manage multiple clocks from different time zones in one interface. You can add any number of global time zones, set a time in one clock, and it automatically updates all others based on that input — perfect for coordinating across teams, clients, or meetings worldwide.
Whether you're working remotely, managing global operations, or just trying to catch a call at the right time — this tool simplifies time zone math instantly.
What Elements Are Involved?
Time Zones: Uses the full IANA time zone database (e.g., Asia/Karachi, America/New_York).
JavaScript + LocalStorage: Ensures time syncing logic and clock data persist even after page reloads.
Browser-based Persistence: Your clock settings are saved locally — no account or backend needed.
Example
You add the following zones:
Asia/Karachi
America/New_York
Europe/London
Then you manually set 5:00 PM in Karachi — the other clocks automatically adjust to show the correct local time in New York and London.
How This Tool Works
Select a time zone from the dropdown and click Add Clock.
Enter or adjust the time on any one clock — all others will update accordingly based on real-world offsets.
Your added clocks and last-edited time are stored in your browser using localStorage, so they remain even if you close or refresh the page.
Use the Remove button to delete individual clocks, or Clear all clocks to reset the list.
