Time Zone Converter

Pick a date, time, and IANA time zones such as Asia/Karachi or America/New_York. Conversion uses platform timezone data — not hardcoded fixed offsets — so daylight saving is handled where supported.

Frequently Asked Questions

Why not use fixed offsets like UTC−5?

Fixed offsets fail when daylight saving changes. IANA zones such as America/New_York carry the rules your platform supports.

Can the date change after conversion?

Yes. A late evening time in one zone can become the next calendar day in another.

What if a local time falls in a DST gap?

Some wall-clock times do not exist during spring-forward transitions. The tool reports that clearly instead of guessing.
