Convert epoch time to a readable date — and back
A Unix timestamp counts seconds since January 1, 1970 UTC. It's the standard way databases, logs, and APIs store a moment in time because it's compact and timezone-independent. Paste a timestamp to see it in your local time, UTC, and ISO 8601, or pick a date to get its timestamp in seconds and milliseconds. Everything runs in your browser.

- 10 digits vs 13 digits?
- 10 digits = seconds, 13 digits = milliseconds. The tool detects and shows both.
- Which timezone is shown?
