Convert between Unix timestamp and ISO 8601 date in both directions, designed for debugging APIs, databases and logs with timestamps.

The Unix timestamp is the number of seconds elapsed since January 1, 1970 (UTC), the standard format for representing dates in most systems, databases and APIs.

Use cases

  • Debugging timestamps returned by an API.
  • Converting an ISO 8601 date to a timestamp for a database query.
  • Checking what date a log value corresponds to.

How it works

  1. 1

    Timestamp to date

    Enter a timestamp in seconds and get the ISO 8601 date in UTC.

  2. 2

    Date to timestamp

    Enter an ISO 8601 date and get its equivalent Unix timestamp.

Frequently asked questions

What unit is the timestamp in?
Seconds, the Unix standard. If your system uses milliseconds (like JavaScript internally), divide by 1000 before entering it.
