Measured entry

shadcn-block-calendar-06

calendarminimal-flat

A client-side date-range picker that presents one month, keeps the selected range in React state, and enforces a minimum stay with a short helper label. It ships as a shadcn registry block built on the shadcn Calendar primitive, react-day-picker, date-fns, Radix Slot, Tailwind classes, and the usual local class-name utility.

Verdict

A focused starting point for booking-style range selection, with clean behavior and no provider requirement. It needs a shadcn-style setup, so it is a better fit for an existing shadcn codebase than a drop-in calendar for a bare React project.

Use it if

  • You need an inline range picker for bookings or reservations with a minimum-stay rule.
  • Your app already uses shadcn conventions, Tailwind theme tokens, and path aliases.
  • You want selection state kept local and can connect it to your own form or availability logic.

Skip it if

  • You need a compact popover field rather than a permanently visible calendar.
  • You need server-driven availability, blocked dates, pricing, or validation included in the component.
  • Your project avoids shadcn and Tailwind conventions and cannot justify recreating their supporting utilities and theme setup.

Providerno provider required in the harness

In a non-shadcn project, add the Calendar primitive and its react-day-picker, date-fns, and Radix Slot dependencies, then provide Tailwind styling, matching theme tokens, the local class-name helper, and the expected import alias. Replace the registry import with your project path.
