- Auto-detects your own timezone as the starting point
Frequently asked questions
Does it account for daylight saving time?
Yes — offsets are computed for the exact date you choose, so DST transitions in either the source or destination timezone are handled correctly.
Where does the timezone data come from?
Your browser's built-in Intl timezone database (the same IANA data operating systems use), so no external lookups or accounts are needed.
