- Use Now to quickly set the reference to your local current time.
- All conversions use browser timezone APIs and respect DST in each IANA zone.
How This Tool Works
This timezone converter relies on the Intl.DateTimeFormat API built into your browser. This method is highly accurate because it uses the same IANA Time Zone database that powers your operating system, ensuring all calculations automatically account for:
- Daylight Saving Time (DST) changes for every supported region (e.g., PST vs. PDT).
- Historical timezone offsets for past dates.
- Future timezone rules for dates up to a certain point.
Privacy & Security
This tool is 100% client-side, meaning no data is ever sent to our servers for conversion. Your chosen time, date, and time zones are processed locally in your browser, guaranteeing your privacy and security.
Troubleshooting
If you suspect an error, ensure your device's operating system clock and time zone settings are correct, as the tool relies on your local configuration for the 'Now' and 'Local Time' features. If you still encounter issues, try clearing the input using the "Clear Time" button.
