About the Timestamp
Convert a Unix timestamp into a readable date, or pick a date and time to get its timestamp. Toggle between seconds and milliseconds, and see the result in your local time, UTC and ISO 8601 format. The Now button drops in the current epoch instantly.
Unix timestamps count the seconds since 1 January 1970 (UTC) and are used throughout programming, logs and APIs. Because the conversion runs in your browser, it's fast, accurate to your time zone, and works without sending anything to a server.

Frequently asked questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since 1 January 1970 at 00:00 UTC, known as the epoch.
What's the difference between seconds and milliseconds?
Many systems store timestamps in seconds, but JavaScript and some APIs use milliseconds (1000× larger). Use the toggle to match your source.
Does it handle my time zone?
Yes. The converter shows both your local time and UTC, so you can read whichever you need.
Is my data uploaded anywhere?
No. All conversion happens locally in your browser, so nothing is sent to a server.
