Event Clock

Live and upcoming events across your gacha games, sorted by what expires next.

You play three or four gacha games. Each has its own calendar, none of them talk to each other, and the only question that actually matters — what runs out first? — takes four browser tabs to answer. This does it in one screen.

No account. No login. Your completed events are saved in your browser and never leave your device.

Status

Early. The parsing pipeline and the interface work end to end against checked-in fixtures; the server, database and scheduler are specified but not built.

Piece	State
Event schema, date parsing, Game8 parser	Built, tested
Genshin Impact and Neverness to Everness sources	Built, tested
Cross-source merge and conflict detection	Built, tested
Web interface	Built
Bun server, SQLite, refresh scheduler, review queue	Specified in docs/, not built

Today the feed is generated offline from fixtures. That is deliberate: it let the interface be built against real parsed data, and it produces exactly the shape the server will serve.

Try it

bun install
bun run build      # parse fixtures → feed, then compile CSS and JS
bunx serve public  # or any static file server

Then open http://localhost:3000.

Commands

bun test                  # full suite, offline, no network
bun run typecheck         # tsc --noEmit
bun run build             # feed + css + js + html into public/
bun run build:feed        # regenerate public/data/events.v1.json from fixtures

# Run one source against its fixture and print what it yields
bun run parse genshin-game8-events fixtures/genshin/game8-events-2026-08-14.html
bun run parse nte-game8-events     fixtures/nte/game8-events-2026-08-14.html --json

How it works

game wikis ──► fetch ──► parse ──► merge ──► validate ──► gate ──► feed ──► browser
                          │          │                     │                  │
                    per-site      per-game            hold anything    localStorage:
                     parser      corroboration        uncertain for      what you've
                                 and conflicts        human review        finished

Parsers are deterministic code. There is no LLM anywhere in the pipeline — no API key, no inference, no per-run cost. A source that cannot be parsed reliably does not get an adapter, rather than getting a model that guesses at it.

Three layers, so sources multiply cheaply. A parser understands one site template (one Game8 parser serves every Game8 page). An adapter binds a URL and a game to a parser. Merge reconciles several sources for the same game. Adding a source for a site already covered is one registry entry.

Nothing is guessed. Every date function returns null rather than inventing a missing year or end date. An event whose end is unannounced is published with no end and rendered distinctly — never filled in with a plausible-looking date.

That last rule is the whole product. A missing event sends you to a wiki; a confidently wrong end date makes you miss content. Given the choice, this ships nothing rather than a guess.

Games

Game	Source	Notes
Genshin Impact	Game8	9 events
Neverness to Everness	Game8	13 events
Arknights: Endfield	—	No source yet, see below

Endfield has no adapter on purpose. Its Game8 page carries no usable dates: every duration reads "Permanently Available", and the schedule is an image grid showing 07/16 with no year and no end date. Supporting it would mean inventing both. It needs a different source.

Honkai: Star Rail, Zenless Zone Zero, Wuthering Waves and Arknights are defined in the schema and awaiting sources.

Adding a source

1. Check robots.txt and the site's terms. If automated access is forbidden, stop — find another source.
2. Capture the page once into fixtures/<game>/<source>-<YYYY-MM-DD>.html.
3. Reuse an existing parser if the site is already covered; otherwise write one implementing SourceParser.
4. Add an entry to SOURCES in src/ingest/adapters/index.ts.
5. Write the expected output and a test. Then check a few events against the live page by hand — a passing test only proves the parser agrees with a file you wrote yourself.

Full walkthrough in docs/INGESTION.md, or run the add-game-source skill.

Conduct

Sources are community wikis, treated as a guest would: robots.txt honoured, a descriptive User-Agent, one request per source per six hours, conditional requests, and raw snapshots cached so iteration never re-fetches. Every event links back to its source.
