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
Convert JWT exp, iat and nbf values
Copy timestamp claims from a JWT payload and convert them into readable local dates, relative time and ISO format.

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.
