Measured entry

shadcn-block-calendar-10

calendarminimal-flat

A client-side, single-date calendar wrapped in shadcn Card primitives, with controlled month and selection state plus a Today shortcut. It ships as a registry block and composes the shadcn calendar, card, and button, relying on React, react-day-picker, date-fns, Radix Slot, Tailwind styling, and the shared class-name utility.

Verdict

A sound, focused composition that builds, mounts, stays within its viewport, and passes the automated accessibility check. It needs a shadcn-style setup and is best treated as a starting shell, since booking logic and a meaningful initial date remain application work.

Use it if

  • You need a compact appointment-date picker with a prominent way to return to today.
  • Your app already uses shadcn registry primitives, Tailwind theme tokens, and the shared utility conventions.
  • You want a controlled single-date example that can feed the selected value into your own booking flow.

Skip it if

  • You need date ranges, time slots, availability rules, or appointment submission out of the box.
  • You want a framework-neutral widget with isolated styles and no shadcn project conventions.
  • You are sensitive to adding a calendar dependency stack for a small date field.
  • You expect the demo's preset selection to remain relevant without replacing its fixed initial date.

Providerno provider required in the harness

In a non-shadcn project, add React DayPicker, date-fns, and Radix Slot; recreate the Calendar, Card, and Button primitives; configure the import alias, Tailwind theme tokens, and shared class-name utility; then adapt the registry imports to local paths. No provider is required.
