Continues the full-year sanctoral import: the Most Precious Blood of Our Lord (Duplex I Classis, full proper office, elevated by Pius XI for the 1933 Redemption jubilee), the Visitation of the BVM (Duplex II Classis, full proper office), St. Leo II, St. Anthony Mary Zaccaria, the Octave Day of Ss. Peter and Paul (own real content, not a bare continuation), Ss. Cyril and Methodius, St. Elizabeth of Portugal, St. Henry, Our Lady of Mount Carmel, St. Vincent de Paul, and St. Ignatius of Loyola. Also fixes a real pre-existing bug surfaced while authoring St. Leo II: an earlier June sanctoral pull had mapped him to "06-28" (his own vita text mentions his burial "upon the 28th day of June," but his actual liturgical feast, per the reference engine's Sancti/07-03.txt, is July 3) with no saints/st-leo-ii.yml ever authored for it -- a wrong-date stub, same class of artifact as the pre-existing St. Apollinaris wrong-date bug already documented in july-sanctoral.test.ts. Removed the stale June 28 entry now that he's correctly authored on July 3. Two day-label tests pinned to Trinity-Sunday-relative dates that now collide with new fixed feasts (Jul 6: Octave Day of Ss. Peter and Paul) were moved to collision-free years/dates, and the July stub test covering "pure octave-continuation days" was updated to a date (July 4) that's still genuinely unmapped, since most of that range turned out to have real content after all.

vu
A static, offline-first PWA for praying the Divine Office — Matins, Lauds, Prime, Terce, Sext, None, Vespers, and Compline — in bilingual Latin/English, for any given date.
This isn't a reconstruction of any single historical breviary. It's a personal design that
draws on several historical sources without reproducing any one of them exactly: hour
structure chiefly from the Monastic Tridentinum (1617), precedence/rubrics from Divino
Afflatu, and a calendar merged from both the Tridentine 1906 and Divino Afflatu calendars,
with more generous handling of commemorations and octaves than any one historical rite used.
See CLAUDE.md (gitignored, not shipped in this repo) or the project's own notes for the full
rationale if you're extending it.
There's no backend and no database — everything is a pre-built static bundle, and the app is designed to keep working fully offline once it's been loaded once.
Development
Requires Node.js (developed against Node 20+).
npm install
npm run dev # start the Vite dev server
npm run build # type-check (tsc --noEmit) and produce a production build in dist/
npm run preview # serve the production build locally
npm test # run the test suite (vitest)
Run a single test file or a subset by name:
npx vitest run tests/hours/vespers.test.ts
npx vitest run -t "some test name"
Running in production
The app is entirely static once built, so "running it" just means serving dist/ — any static
file host works, as long as it falls back to index.html for unknown paths (the app does its
own client-side routing for URLs like /2026-08-09/prime).
Docker
A Dockerfile builds the static bundle with Node and serves it with Caddy:
docker build -t vu .
docker run -p 8080:80 vu
Or with Docker Compose (docker-compose.yml is included):
docker compose up -d --build
This serves the app on http://localhost:8080. Put a reverse proxy/TLS terminator in front of
it for a real deployment; the container itself just listens on port 80 internally and has no
configuration, secrets, or external dependencies.
Without Docker
Any static file server works — build the app, then serve dist/ with SPA-style fallback
routing. For example, with Caddy directly:
npm run build
caddy file-server --root dist --listen :8080
(For a real deployment you'll want a fallback rule so unknown paths resolve to index.html —
see the Caddyfile in this repo for the pattern.)
