## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

- 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
