About Unix Timestamp Converter

Works in both directions, which is exactly what you want when a log line hands you 1735689600 and the bug report hands you a date. Epoch values are also the usual culprit when a record turns up dated 1970.

Translate a Unix epoch timestamp into a readable date and time — in both UTC and your local zone — and convert dates back to epoch seconds or milliseconds. All conversion is computed locally.

Convert between Unix epoch time, ISO 8601 and human-readable dates in both directions, including relative time like '3 hours ago'. It is an everyday helper for working with logs, API responses, database timestamps and debugging time-zone issues.

Paste an epoch value to read it as a date, or pick a date to get its timestamp. Both seconds and milliseconds are shown, since APIs disagree about which one they mean by 'timestamp'.

Frequently asked questions

What is a Unix timestamp counting from?

Seconds elapsed since midnight UTC on 1 January 1970, known as the epoch. Because it is a plain number with no timezone attached, it is unambiguous — which is exactly why systems store and exchange time this way.

Is my timestamp in seconds or milliseconds?

Count the digits. Ten digits is seconds (the Unix convention); thirteen is milliseconds (the JavaScript convention). Feeding milliseconds into a seconds-based parser lands you tens of thousands of years in the future — a very common bug.

What is the year 2038 problem?

A signed 32-bit timestamp overflows on 19 January 2038, wrapping to a negative number and therefore to 1901. Modern systems use 64-bit values, but embedded devices and old database columns can still be affected.

Common Use Cases

•Reading a timestamp from a log line or database row
•Checking when a token or cache entry actually expires
•Converting an API's numeric date into something human-readable
