FAQ

Common questions

How is this different from the Timezone converter?
They solve the same problem with different pickers — this tool works from a fixed list of common abbreviations (EST, CST, JST, and so on), while Timezone converter lets you pick from the full IANA list of every real-world region and city. Use whichever list has the zone you're after.
Why do some abbreviations mean more than one real timezone?
Three- and four-letter abbreviations aren't globally unique — this list includes both "IST" options (India Standard Time and Israel Standard Time) as separate, individually selectable entries specifically because of that ambiguity.
Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
