What is Unix Timestamp Converter?

The Unix Timestamp Converter translates between Unix epoch time and human-readable date formats. It features a live epoch clock, auto-detects input scale (seconds, milliseconds, microseconds, nanoseconds), and outputs in ISO 8601, UTC, RFC 2822, and relative time. Essential for developers working with APIs, databases, and log files.

How to Use

  1. 1Enter a Unix timestamp to convert it to a human-readable date
  2. 2Or switch to Date → Timestamp mode and enter date/time values
  3. 3Click any output row to copy it to clipboard
  4. 4Change the timezone to see conversions in different regions

Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It's a universal way to represent time in computing, used by databases, APIs, log files, and programming languages.
What is the Year 2038 problem?
The Y2K38 problem occurs because 32-bit systems store Unix timestamps as a signed 32-bit integer, which maxes out at 2,147,483,647 (January 19, 2038 03:14:07 UTC). After that, it overflows to a negative number. Most modern systems use 64-bit timestamps to avoid this.
What is the difference between seconds and milliseconds timestamps?
A seconds timestamp has 10 digits (e.g., 1711234567), while milliseconds has 13 digits (e.g., 1711234567890). JavaScript's Date.now() returns milliseconds, while most Unix tools and APIs use seconds. This tool auto-detects the scale.
