Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is a widely used standard in computing for representing dates and times as a single integer, independent of time zones. Millisecond-precision timestamps (13 digits) are also common in JavaScript and modern APIs.
How to convert a Unix timestamp to a date
Enter the Unix timestamp in the "Unix Timestamp → Date" section. The tool automatically detects whether it is in seconds (10 digits) or milliseconds (13 digits) and displays the result in ISO 8601, UTC, and local time formats. Use the "Now" button to insert the current timestamp.
