About this Tool

Effortlessly sync with the world. The Time Zone Converter eliminates confusion when dealing with global times. Whether you're scheduling a meeting with an international client, planning your next trip, or coordinating with a remote team, this tool provides instant, accurate time conversions. See the exact time anywhere on the planet with a clean, simple interface.

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.
  • A project manager finding the perfect meeting time for a team spread across continents.

  • A remote worker making sure they don't message a colleague in the middle of the night.
  • Someone sending birthday wishes at exactly midnight in a friend's time zone.
  • Instant & Accurate: Real-time conversions between any two global time zones.
  • Clear Comparison: A side-by-side display makes it easy to see the time difference.
  • DST Aware: Automatically adjusts for Daylight Saving Time so you don't have to.
  • Comprehensive List: Search from a clean, IANA-standard list of time zones.
  • Swap Functionality: Quickly flip your 'From' and 'To' locations with one click.
  • Completely Private: All calculations happen in your browser. Your data is never saved.

Powered by `Intl.DateTimeFormat`, the tool renders a single UTC timestamp in the context of different IANA time zones. This modern approach guarantees accuracy by respecting regional offsets, DST rules, and date boundaries, providing a reliable conversion every time.

What are IANA time zones?

They are standardized identifiers for time zones, like 'America/Los_Angeles' or 'Europe/London'. They are the global standard and automatically account for local rules and DST.

Why is the converted day sometimes different?

When the time difference between two zones is large, it can cross over midnight. For example, evening in New York might already be the next morning in Tokyo.

Is my data private?

Absolutely. All conversions happen locally on your device. Nothing is ever stored or transmitted.

All calculations and data processing for this tool are performed locally in your browser. We do not send any of your data to our servers, ensuring your information remains private and secure.
