About This Tool

Free Unix timestamp converter online — convert a Unix epoch timestamp (seconds or milliseconds since January 1, 1970) into a human-readable date and time, or convert any date back into its Unix timestamp. Supports both directions with live conversion as you type, and automatically detects whether a pasted timestamp is in seconds or milliseconds. Developers use this daily to debug API responses and database records that store dates as epoch time, to inspect JWT `iat`/`exp` claims, or to construct timestamps for log filtering and cron scheduling. A live "current timestamp" display is also shown for quick reference. All conversion happens locally in your browser.

How to Use

  1. 1

    Paste a timestamp or pick a date

    Enter a Unix timestamp to convert to a date, or use the date picker to convert a date to a timestamp.

  2. 2

    Choose seconds or milliseconds

    Select the correct unit if converting from a timestamp — most APIs use seconds, JavaScript uses milliseconds.

  3. 3

    Read the result

    See the converted value in both formats along with the current live timestamp for reference.

Frequently Asked Questions

What is a Unix timestamp?+
A Unix timestamp (or epoch time) is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC. It is a standard way to represent a point in time independent of timezone or calendar format.
How do I know if my timestamp is in seconds or milliseconds?+
A timestamp in seconds for a recent date is typically a 10-digit number; the same date in milliseconds is a 13-digit number. The tool lets you toggle between the two if the auto-detected format looks wrong.
