This converter uses your browser's built-in Internationalization API (Intl) for maximum accuracy. By formatting a single time object according to different IANA time zone rules (like 'America/New_York' or 'Asia/Tokyo'), it ensures every conversion is precise and accounts for regional complexities like Daylight Saving Time, all without needing external servers.

1. Pick the date and time you want to convert.
2. Select your 'From' and 'To' time zones from the dropdown lists.
3. The converted date and time appear instantly.
4. Use the 'Swap' button to quickly reverse the conversion.
5. The tool automatically handles Daylight Saving Time (DST) for you.
