FAQ

Frequently asked questions

Quick answers to common questions about the Time Zone Converter.

What does the Time Zone Converter do?

It converts a date and time you pick from one time zone to another, and shows the current time in major cities around the world.

Is the Time Zone Converter free to use?

Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.

Is my input safe when I use this tool?

Yes. The date, time and zones you choose are processed entirely on your own device — nothing is sent to a server.

Does it account for daylight saving time?

Yes. Conversions use each zone's actual rules for the date you picked, so daylight saving time is applied correctly for that specific date rather than a fixed year-round offset.

What does the "Swap" button do?

It exchanges the From and To time zones instantly, so you can quickly see the conversion in the opposite direction without re-selecting both zones.

Can I convert a time in the past or future?

Yes. Pick any date and time — past or future — and the converter applies that date's correct zone rules, not just today's.

Can I use the Time Zone Converter on my phone?

Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.

Does the Time Zone Converter have any limitations?

It covers standard IANA time zones your browser supports, which includes essentially every real-world zone in current use.
