How to Convert Unix Timestamps to Human Dates

Converting a Unix timestamp (also known as Epoch time) to a readable format is essential for debugging logs, database management, and software development. Our tool supports both single inputs and bulk timestamp conversion, allowing you to process large lists of data instantly.

Difference Between Seconds and Milliseconds

A common point of confusion is whether a timestamp is in seconds or milliseconds. Unix time traditionally counts seconds since Jan 1, 1970. However, JavaScript and many modern APIs use milliseconds. Our converter automatically detects the length: a 10-digit number is treated as seconds, while a 13-digit number is treated as milliseconds.
