How to Use the Timestamp Converter
The live clock at the top shows the current Unix timestamp, updating every second. Use Unix Timestamp → Date to convert a numeric timestamp into a human-readable date. Use Date → Unix Timestamp to convert a date and time back to a Unix timestamp.
Toggle between Seconds and Milliseconds depending on your timestamp format. JavaScript and Java typically use milliseconds, while Unix/Linux, Python, and PHP use seconds.
What Is a Unix Timestamp?
A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It is the standard way computers track time because it is timezone-independent and easy to compare.
Unix timestamps are used in databases, APIs, log files, JWT tokens, and almost every backend system. Converting between timestamps and human-readable dates is a common task in software development, data analysis, and system administration.
