About Time Zone Converter
Pick a date and time in your source time zone, add as many target time zones as you need, and see the converted time in each instantly. Unlike many time zone tools that rely on an external API, this converter uses the IANA time zone database already built into your browser (via the Intl API), so it works entirely offline and always reflects the correct current daylight saving time rules for each zone. Useful for scheduling meetings across time zones, planning international calls, or just checking what time it is somewhere else right now.
