Closes the tabled "Easter's own octave" mechanism gap. resolveDay only ever checked yesterday/tomorrow for an inbound transfer - a single hop - so anything impeded in Holy Week just vanished rather than reappearing after the Octave. Live-verified the real behavior first (2033 proof year): a candidate skips the whole privileged span and keeps walking forward, FIFO by native date, until it lands; a transferred-in candidate never gets the "still gets a nod" commemoration a native occurrence of the same rank would along the way (confirmed with the Annunciation, zero commemoration anywhere in the span). Also fixed Low Sunday itself, which needed the same privileged-sunday treatment as Easter Day. Built resolveForwardTransferLanding: a bounded queue simulation that reuses applyIncomingTransfer unchanged per hop - its existing privileged-feria-major no-op was already the right single-hop refusal, it just needed a real cascade around it instead of a dead end.

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.)
