What Is a Timestamp Converter?
This tool converts between human-readable dates and Unix timestamps automatically — paste in a date and get back its Unix timestamp, or paste in a Unix timestamp (seconds or milliseconds) and get back the matching calendar date, in ISO 8601, UTC and your local time zone.
It auto-detects which kind of input you've given it based on whether it looks like a number or a date string, and further guesses whether a numeric timestamp is in seconds or milliseconds based on its length — removing the need to specify a direction manually for most everyday use.

A 10-Digit Number Is Usually Seconds
Most Unix timestamps in seconds are 10 digits (until the year 2286); 13 digits usually means milliseconds.
Use the Relative Time for Quick Sanity Checks
The "X days ago" style output is a quick way to confirm a timestamp is roughly what you expect.
