What Is the Unix Timestamp Converter?
Unix time (epoch time) is the number of seconds elapsed since January 1, 1970 at 00:00:00 UTC. It is widely used in programming, databases, and APIs.
Formula
How to Use
Enter a Unix timestamp (in seconds or milliseconds) to convert to a human-readable date. Or enter a date and time to get the Unix timestamp.
Example Calculation
The timestamp 1700000000 corresponds to November 14, 2023, 22:13:20 UTC. The timestamp 0 is January 1, 1970 — the Unix epoch.

Frequently Asked Questions
What is the Unix epoch?
The Unix epoch is January 1, 1970, 00:00:00 UTC — the starting point for Unix time measurements.
Seconds vs milliseconds?
JavaScript uses milliseconds (13 digits), while most server-side languages use seconds (10 digits). This tool handles both.
What is the Year 2038 problem?
32-bit signed integers overflow at 2,147,483,647 seconds after epoch, which is January 19, 2038. Most modern systems use 64-bit integers, solving this.
