This Duplex I classis feast (instituted by Pius IX, 1847) didn't exist anywhere in vu's calendar. Dated per the older, pre-1955 reckoning -- Wednesday after the 2nd Sunday after Easter (Easter+17) -- rather than the 1913 Pius X reform's later placement on the 3rd Sunday after Easter itself, per direct instruction. Mechanism: one new temporal-feast record plus a new EASTER_OFFSET_STARTS table entry (the only code change -- everything else is the existing generic anchor-driven resolution). Authored the feast day's own Matins reading and its full 7-day octave (days 2/3/4/6/7/8; day 5, the Sunday, has no override in the source at all, correctly left unauthored). Fixed one real collateral effect: an existing fixed-year calendar test (St. Pudentiana vs. St. Peter Celestine, 2038-05-19) broke because that date now falls on this octave's own closing day, tying Celestine's rank against the octave's threshold -- the app's own documented tie-break correctly favors the octave that year. Moved the proof date to 2033. Also bumped the PWA precache file-size cap (6 MiB -> 8 MiB) since this content pull pushed the main bundle past the previous limit.

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.)
