What is World Clock?
World Clock displays the current time in multiple cities and time zones simultaneously, with live updating. Shows time differences relative to your local time.
When to use this tool
- Monitoring business hours across global offices
- Knowing when to call colleagues in other time zones
- Tracking market opening/closing times (NYSE, LSE, TSE)
- Planning international travel departures and arrivals
- Coordinating real-time collaboration across continents
How it works
Uses Intl.DateTimeFormat with IANA timezone identifiers (e.g., America/New_York, Asia/Tokyo) to render the current time for each selected city. A setInterval updates the display every second.
