About this Time Zone Converter
Enter a date & time in a base time zone and instantly see it in one or two other time zones. The converter uses IANA time zone rules via the browser’s internationalization engine, so daylight saving transitions are handled automatically.
Use the 12-hour toggle, the Now shortcut, and the Copy Link button to share a pre-filled conversion with others. Everything runs locally in your browser—nothing is uploaded or stored.
Note: Some wall times don’t exist during DST “spring forward”; we nudge to the next valid minute.
Time Zone Converter: FAQs
Does this handle daylight saving time?
Yes. Conversions use the selected IANA zones with their DST rules.
Why is my time adjusted slightly on DST change dates?
Some wall times are skipped or repeated during DST changes. The tool finds the nearest valid instant.
Can I share a specific conversion?
Yes. Click Copy Link to copy a permalink containing your date/time and zones.
Is my data private?
Yes. The converter works entirely in your browser.
