history

Project history and usage

ddate converts Gregorian dates to the Discordian, or POEE, calendar. The standalone repository describes itself as the same ddate version from util-linux 2.20, kept separate because util-linux no longer builds ddate by default.

Project history

The bo0ts/ddate repository was created in 2011 after ddate's status in util-linux changed. Its README preserves the compact converter and includes the calendar's seasons, weekdays, holidays, and Saint Tib's Day rules.

Adoption history

ddate survives as a small Unix culture package: not operationally critical, but still present in Homebrew, Linux distributions, and Nix for users who want the classic command without depending on util-linux to ship it.

How it is used

Users run ddate as a date-conversion CLI. The bundled manpage and README document the Discordian calendar rather than application configuration, so it has no persistent config or credential file.

Why package nerds care

Package nerds care about ddate because it is a tiny artifact of Unix humor and distribution policy. Its continued packaging shows how small commands can outlive their original host project when users still value the behavior.

Timeline

  • 2011: Standalone GitHub repository created
  • 2011: README says the code matches util-linux 2.20
  • 2011: Project preserved because util-linux stopped building ddate by default
