history
Project history and usage
jcal is a small Unix-style calendar package for the Jalali, or Persian, calendar. The package exposes jcal and jdate executables and is curated as a cal-like date conversion and calendar-display tool.
Project history
The project is hosted on GNU Savannah/Nongnu and publishes documentation through nongnu.org. Its shape follows the traditional Unix model: separate small commands, manual pages, and source distribution from a free-software project host rather than a large application framework.
Adoption history
jcal appears in Homebrew, Debian, Ubuntu, Fedora, and Nix package metadata, which points to a narrow but real adoption pattern: systems that need a terminal Jalali calendar tool package it alongside other locale and date utilities.
How it is used
Users run jcal for Jalali calendar display and jdate for date conversion or Jalali-aware date output. The official documentation set includes separate jcal and jdate manual pages.
Why package nerds care
jcal matters less as a large upstream and more as a representative Unix localization package: a tiny command-line utility that keeps a non-Gregorian calendar workflow available through standard package managers.
Timeline
- 2000s: The project was hosted on Savannah/Nongnu and documented through nongnu.org manual pages.
- Package metadata: Homebrew, Debian, Ubuntu, Fedora, and Nix package names preserve the jcal command-line tool for Jalali calendar workflows.
Related projects
- Related concepts include the Jalali/Persian calendar, Unix cal-style tools, date conversion utilities, GNU Savannah hosting, and distribution localization packages.
