Unix Timestamp Converter

Convert Unix timestamps to human-readable dates or dates back to Unix timestamps. The live clock shows the current timestamp, and all conversions happen in your browser.

How to Use

  1. View the live clock at the top showing the current Unix timestamp
  2. Convert timestamp to date: Enter a Unix timestamp (seconds or milliseconds) in the left panel
  3. Convert date to timestamp: Pick a date and time in the right panel
  4. Change timezone: Search for a timezone using the dropdown

Understanding Unix Time

Unix time counts the number of seconds since the Unix epoch: midnight UTC on January 1, 1970. This simple counting system is used universally in computing because it is timezone-independent, easy to compare (just compare two numbers), compact to store, and unambiguous across systems and programming languages.

Most programming languages and databases support Unix timestamps natively. In JavaScript, Date.now() returns the current time in milliseconds. In Python, time.time() returns seconds. APIs commonly use Unix timestamps in their payloads to avoid date format parsing issues.

Auto-Detection

This tool automatically detects whether your input is in seconds or milliseconds. If the number is greater than 10^12, it is treated as milliseconds; otherwise, it is treated as seconds. A small indicator shows which format was detected.
