Free Unix Timestamp Converter & Epoch Time Tool

Last Updated: August 13, 2026

A Unix timestamp converter converts seconds or milliseconds elapsed since January 1, 1970 (UTC epoch) into human-readable date and time strings across UTC and local timezones.

What is a Unix Timestamp?

A Unix timestamp (also known as Epoch time or POSIX time) is a system for describing a point in time defined as the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix Epoch), minus leap seconds. It is widely used in operating systems, databases, software applications, and API protocols for storing timestamps neutrally without timezone ambiguity.

Key Features of This Converter

  • Live Epoch Clock: Displays the current Unix timestamp updated live every second.
  • Bi-Directional Conversion: Instantly convert Unix timestamps to human-readable dates or pick any calendar date/time to generate its Unix timestamp.
  • Seconds & Milliseconds Support: Automatically detects 10-digit (seconds) and 13-digit (milliseconds) timestamps.
  • Timezone Flexibility: Shows conversions in both UTC and your local device timezone.
