Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It is a universal, timezone-independent way to represent a specific moment in time.
How do I convert a Unix timestamp to a readable date?
Divide millisecond timestamps by 1000 to get seconds, then use a date library or this tool. In JavaScript: new Date(timestamp * 1000).toISOString().
Why does Unix time start at 1970?
January 1, 1970 was chosen as the epoch when Unix was being developed in the early 1970s. It was a convenient recent date that kept numbers small for the computing resources of the time.
