Why the offset depends on the date
A zone is not a fixed offset. New York is UTC−5 in January and UTC−4 in July, and the switch dates have moved several times over the years. Converting with today's offset therefore gives the wrong answer for a meeting last spring.
This tool resolves the offset for the specific instant you enter, using the browser's IANA time zone database — the same data the operating system uses.
Scheduling across zones
Pick a reference zone and every other row shows the difference from it, so "14:00 my time" becomes readable for everyone at once.
When you write the time down afterwards, write the UTC value too. "3pm Tuesday" is ambiguous the moment it crosses a border; "2024-06-18T06:00Z" is not.
Frequently asked questions
Why does it not use city names like EST or PST?
Abbreviations are ambiguous — IST is India, Ireland and Israel — and they do not carry daylight-saving rules. IANA identifiers like America/New_York do.
How do I convert a past or future date?
Type it in: an ISO 8601 string, a Unix timestamp, or "now". The historically correct offset for that date is applied.
