+# dayjs-hijri-plus — PRI (Per-Repo Instructions)
+
+**PPI:** `~/Sites/acamarata/.claude/CLAUDE.md`
+
+## What This Is
+
+A Day.js plugin that adds Hijri calendar support. Converts Gregorian dates to and from
+Hijri, provides Hijri-aware formatting, and delegates all calendar logic to hijri-core.
+Supports Umm al-Qura (UAQ) and FCNA/ISNA calendars out of the box. Custom calendar
+engines can be registered at runtime.
+
+**npm:** `dayjs-hijri-plus@1.0.0`
+**Language:** TypeScript
+**License:** MIT
+
+## Key Technical Details
+
+- Peer dependencies: `dayjs@^1.0.0`, `hijri-core@^1.0.0`
+- Plugin pattern: call `dayjs.extend(hijriPlugin)` once at startup
+- Instance methods added: `toHijri()`, `formatHijri()`, `hijriYear()`, `hijriMonth()`, `hijriDay()`
+- Static factory added: `dayjs.fromHijri(hy, hm, hd, options?)`
+- Hijri format tokens: `iYYYY`, `iMM`, `iDD`, `iD`, `iMMMM` — non-Hijri tokens pass through to dayjs
+- Options argument selects calendar: `{ calendar: 'uaq' }` (default) or `{ calendar: 'fcna' }`
+- Dual CJS/ESM build via tsup
+- Zero runtime dependencies (peer deps are provided by the consumer)
+
+## Architecture
+
+`src/index.ts` is the plugin entry point — exports the default plugin function and any
+types. `src/types.ts` holds shared type definitions. Built to `dist/` (gitignored) with
+`.cjs` and `.mjs` outputs plus dual type declarations.
+
+## Commands
+
+- `pnpm install` — install dev deps
+- `pnpm build` — tsup build
+- `pnpm test` — run test.mjs + test-cjs.cjs
+- `pnpm run typecheck` — tsc --noEmit
+
+## Important Notes
+
+- This is a plugin for Day.js — call `dayjs.extend(hijriPlugin)` before using any methods
+- hijri-core provides the actual calendar engine — this package is a thin adapter
+- Changes to hijri-core's API may require updates here
+- dayjs is a peer dep — the consumer's installed dayjs instance is used (no bundled copy)
