The program is licensed as public domain, all rites reversed (English about " all twisted rites ").

The program ddate is included as part of the Linux package util -linux by default on many Linux distributions. As of version 2.23, however, is ddate no longer part of the standard package.

For Microsoft Windows ddate can be found in the collection CygUtils program for Windows.
