About Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and back, instantly and entirely in your browser. Paste a timestamp in seconds or milliseconds to see it as ISO 8601, UTC, your local time, and relative time ("3 hours ago"), or pick a date and time to get the matching timestamp. A live ticker shows the current timestamp for quick reference.
- Converts both ways — timestamp to date and date to timestamp
- Supports both seconds and millisecond timestamps
- Live current-timestamp ticker plus relative-time display
Frequently asked questions
What is a Unix timestamp?
The number of seconds (or milliseconds) that have elapsed since January 1, 1970 UTC — the standard way computers represent a point in time.
Does this account for timezones?
A Unix timestamp itself is timezone-independent; this tool shows it in both UTC and your browser's local timezone so you can read it either way.
