Frequently asked questions
Why include the date when converting time zones?
Daylight saving starts and ends on different dates in the US, UK and Europe, so the gap between zones changes during the year.
Is the Time Zone Converter free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Does it handle daylight saving time?
Yes. Conversions use your browser's time zone database (IANA), which applies daylight saving rules for the date you enter.
