# Date Picker

> The everyday date input: a field-style trigger that opens a calendar popover. Click the caption to zoom out to months and years, page with arrows or PageUp/PageDown, and pick with the keyboard. Today dot, blocked and out-of-range days, Today and Clear shortcuts, and a six-week grid that never changes height.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/date-picker/date-picker.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/date-picker
```

Registry item JSON: https://www.assembli.design/r/date-picker.json (send `Authorization: Bearer <api key>`)
