Unix Timestamp Converter
Convert Unix epoch time to a readable date, or a date back to a timestamp — both directions, live.
Timestamp
Or a date
Convert epoch time both ways
Unix time counts seconds since midnight UTC on January 1, 1970 — the "epoch." It's used throughout databases, APIs, and log files because it's timezone-independent and easy to compare or sort. Enter a timestamp to see its full date breakdown, or set a date and time to get the equivalent timestamp back.

Frequently asked questions
Unix time is traditionally measured in seconds, but JavaScript's Date object and many web APIs use milliseconds since the epoch instead — this tool shows both so you can grab whichever your system expects.
The timestamp itself is timezone-independent, but the "local time" field converts it using your browser's detected timezone, so it will naturally differ from someone viewing the same timestamp elsewhere.
Systems that store Unix time as a signed 32-bit integer overflow on January 19, 2038 — this tool uses standard 64-bit JavaScript numbers internally, so it has no trouble with dates well beyond that.
