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 widely used in programming to represent points in time in a timezone-independent way.

How do I convert a Unix timestamp to a human-readable date?

Enter your Unix timestamp in the converter above and select your target timezone. The tool will instantly display the corresponding date and time in your chosen format.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds (10 digits, e.g., 1700000000) measure time in whole seconds. Millisecond timestamps (13 digits, e.g., 1700000000000) provide finer precision and are commonly used in JavaScript with Date.now().

What is the maximum Unix timestamp value?

The maximum 32-bit signed Unix timestamp is 2147483647 (January 19, 2038), known as the Year 2038 problem. Modern 64-bit systems support timestamps far beyond this limit.
