How it works
Convert Unix timestamps and epoch time to readable dates, or convert dates back to Unix timestamps. Useful for APIs, logs, databases and JWT fields such as exp, iat and nbf.
Practical examples
Read Unix timestamps from logs and APIs
When a server log or API response contains epoch time, quickly convert it to a readable date in your local timezone.
Convert a date to Unix timestamp
Enter a date in MM/DD/YYYY HH:mm format to get Unix timestamp values in both seconds and milliseconds.
FAQ
What is a Unix timestamp?
A Unix timestamp, also called epoch time, is a number representing the time elapsed since January 1, 1970 at 00:00:00 UTC.
What is the difference between seconds and milliseconds?
Unix timestamps are often stored in seconds, while JavaScript and many APIs use milliseconds. This tool supports both formats.
Is the conversion sent to a server?
No. Timestamp conversion happens directly in your browser without sending data to external servers.
