About this tool

Timestamps are everywhere in software — API responses, database fields, log files, JWT claims. This tool converts between different timestamp formats instantly.

Unix timestamp (epoch seconds/milliseconds) ↔ ISO 8601 (2024-01-15T09:30:00Z) ↔ RFC 2822 (Mon, 15 Jan 2024 09:30:00 +0000) ↔ Human-readable (Monday, January 15, 2024 at 9:30 AM UTC)

Enter a timestamp in any format and all other representations update in real-time. A live clock shows the current timestamp so you can quickly compare relative times.

Supports timezone conversion — see what a UTC timestamp looks like in New York, London, Tokyo, or your local timezone. Also handles JavaScript's millisecond timestamps (13-digit numbers) automatically.

Frequently Asked Questions

What is a Unix timestamp?
Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC.
Why does my JavaScript timestamp have 13 digits?
JavaScript uses milliseconds since epoch, not seconds. Divide by 1000 to get the Unix timestamp in seconds.
What is ISO 8601?
ISO 8601 is an international standard for representing dates and times. Example: 2024-01-15T09:30:00Z (the Z means UTC).
How do I get the current Unix timestamp?
Click the 'Now' button or run Math.floor(Date.now() / 1000) in your browser console.
