Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and back — with UTC or local time, relative time, ISO 8601 / RFC formats, second and millisecond support, and batch conversion.
1780909975About the Unix Timestamp Converter
A Unix timestamp counts the number of seconds (or milliseconds) since the Unix epoch — 00:00:00 UTC on 1 January 1970. Bytewrench's converter turns timestamps into human-readable dates and converts dates back into timestamps, showing both UTC and your local time zone.
It's the quickest way to debug log lines, API responses and database fields that store time as an integer.
Convert a timestamp to a date, or pick a date to get its timestamp.
See both the UTC value and your local-time equivalent side by side.
Handles both second- and millisecond-precision timestamps.

Frequently asked questions
What is a Unix timestamp?
It's the number of seconds elapsed since the Unix epoch, 00:00:00 UTC on 1 January 1970, used widely in programming to represent a point in time.
Seconds or milliseconds?
Unix timestamps are traditionally in seconds (10 digits today), while JavaScript uses milliseconds (13 digits). This tool supports both.
What time zone is a timestamp in?
A Unix timestamp is always based on UTC. This converter shows both the UTC date and your local-time equivalent.
What is the year 2038 problem?
Systems that store Unix time in a signed 32-bit integer overflow on 19 January 2038. Modern 64-bit timestamps avoid this limitation.
