Frequently asked questions
Does this handle daylight saving time correctly?+
Yes — time zone offsets are computed for the exact date you enter, not a fixed year-round offset, so it correctly accounts for daylight saving time on both ends (and for zones that don't observe it at all).
What time zone does it start with?+
It defaults to your device's own time zone (detected automatically) as the "From" zone, and UTC as the "To" zone — change either to whatever you need.
Where does the list of time zones come from?+
Your browser's built-in IANA time zone database — the same one your operating system uses — so it's always current with the latest daylight saving rules, without this site needing to ship or update its own copy.
