Frequently asked questions

Does it handle daylight saving time?

Yes. Offsets come from your browser's time zone database for the exact date you pick, so the changes of daylight saving time are applied automatically in every zone.

How does the meeting planner work?

It checks each hour of the day in your chosen zone and fills the hours when all listed zones are between 09:00 and 17:00 local time, so you can find a time that suits everyone.

Which time zones are available?

Every zone your browser knows, listed by its standard name such as Europe/London or Asia/Tokyo. Type part of the name to search. Everything runs in your browser.

Are my files uploaded anywhere?

No. Time Zone Converter runs entirely in your browser. Your files are processed on your device and are never sent to a server.

Is there a file size limit?

No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.

Is Time Zone Converter really free?

Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
