Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/directoriumapp/ordo/archive/refs/heads/develop.zipThe traditional Roman liturgical calendar for WordPress — Introíbo ad altáre Dei.
Ordo is a WordPress plugin that presents the traditional Roman liturgical calendar on any site. Its first release is a standalone MVP that bundles the Directorium engine and works with no external dependency; a later release refactors it into a thin client of the Directorium API (caching in WP transients and degrading gracefully when the API is unreachable).
It ships a masthead calendar strip, the [ordo_today] and [ordo_calendar] shortcodes (and
matching blocks), a day view (a modal via REST plus shareable /ordo/YYYY-MM-DD/ pages), and a
tabbed settings screen with white-label palettes. The interface re-implements the established
navy/gold/parchment "Illuminated Breviary" design.
Status
Pre-release — v0.1.0 in progress. See the roadmap.
Install
Download the latest ordo.zip from Releases, then in WordPress go to
Plugins → Add New → Upload Plugin, upload the zip, and activate. Requires PHP 7.4+ and a
supported WordPress version.
Development
Work branches off develop, lands via squash PRs with Conventional-Commit titles, and releases are
cut automatically by release-please (the plugin header and readme.txt stable tag are kept in
sync). No runtime build step — Node is used only to bundle assets at build time.
Licence
© 2026 Directorium. The plugin is licensed GPL-2.0-or-later (see LICENSE) — the licence
WordPress plugins are distributed under. It bundles the Directorium Core engine (under
src/Core/, vendored by bin/vendor-core.php), which is licensed
AGPL-3.0-or-later (see src/Core/LICENSE); the two are compatible because
GPL-2.0-or-later reaches GPLv3, with which AGPL-3.0 combines. The compiled calendar dataset
(src/Core/data/corpus/) is released under CC0.
