Time Zone Converter

About Time Zone Converter

Coordinating anything across timezones — a call, a deadline, a launch — usually means mental math with UTC offsets and remembering who observes daylight saving. This tool shows live, updating clocks for several timezones at once, side by side, using your browser's built-in Intl timezone support rather than any external time API.

A default set of commonly needed zones is shown on load — UTC, New York, Los Angeles, London, Kolkata, Tokyo, and Sydney — and you can add any additional IANA timezone name (like Europe/Paris or Asia/Singapore) to the list. Each clock updates every second and automatically accounts for daylight saving time changes, since it relies on the browser's own timezone database rather than a static offset.

This is genuinely useful for remote teams checking who's currently in their working hours, scheduling a call across regions, or just satisfying curiosity about what time it is somewhere else right now — all without opening a dozen separate searches.

How it works

1. View the default zones. UTC and six commonly needed regional times.
2. Add any IANA timezone. Type a name like Europe/Paris to add it.
3. Watch live updates. Every clock updates every second automatically.
