Timestamp or Date

Enter a timestamp or date, or use Example.

A Unix timestamp is just a count of seconds since a fixed point with no timezone attached to it at all, which is exactly why the same epoch value renders as a completely different local time depending on which timezone it's actually being viewed in, a detail that trips people up comparing a log entry generated on a server in one timezone against a reader sitting in another. This tool converts between Unix timestamps, ISO 8601, and human-readable dates with timezone support built in, showing the same instant correctly across whichever timezone actually matters.

Useful for converting a raw timestamp found in a log file into an actual readable date and time, checking what a specific epoch value means in a different timezone than the one it was generated in, or converting a date into the Unix timestamp format an API expects.

Quick answers for Timestamp Converter

How does it know if I've entered a timestamp or a date?
If your input is all digits it's treated as a Unix timestamp, automatically detecting seconds versus milliseconds based on its size, anything else is parsed as a date string instead.
What formats does the result show?
For a timestamp input you get local date and time, UTC, ISO 8601, and both Unix seconds and milliseconds, for a date-string input you get the reverse: both Unix formats, ISO 8601, and UTC.
Is there a shortcut to convert the current moment?
Yes, a "Now" button fills the input with the current Unix timestamp in seconds and converts it immediately.
