Frequently Asked Questions

Is DST handled correctly?
Yes. The tool relies on the browser's Intl.DateTimeFormat which uses up-to-date IANA data, so daylight saving transitions are applied automatically.
Which timezones are available?
All IANA timezones supported by your browser (via Intl.supportedValuesOf('timeZone')), typically 400+ entries.
Can I convert to many timezones at once?
Yes. Add as many target timezones as you need — the converted times render side-by-side instantly.
