Converting between time zones

IANA time zones (like America/New_York or Asia/Tokyo) are the authoritative identifiers used by operating systems, databases, and programming languages. Unlike fixed offsets such as UTC−5, IANA zones automatically account for daylight saving time transitions, so a given wall-clock moment in New York maps to the correct London time whether it's summer or winter. This converter parses your input datetime as a UTC instant and then formats it in whichever zones you choose, entirely in your browser using the built-in Intl.DateTimeFormat API — no data leaves your device.
