Measured entry

originui-comp-41

calendarminimal-flat

A client-side single-date picker with a segmented text field, calendar trigger, and popover calendar. It ships as a shadcn registry component and composes React Aria primitives with Origin UI calendar and date-field registry files, internationalized date handling, Lucide icons, Tailwind classes, theme tokens, and a shared class-name utility.

Verdict

A solid, functional date-picker composition for teams already invested in React Aria and Origin UI conventions. It builds and mounts in the prepared harness, but the default colors need contrast remediation. Bare projects cannot drop it in directly; it needs a shadcn-style setup and its registry dependencies.

Use it if

  • You need keyboard-aware date entry and calendar selection in the same control.
  • Your app already uses React Aria and shadcn-style registry components.
  • You want locale-aware date segments backed by internationalized date values.

Skip it if

  • You need a dependency-light native date input rather than React Aria and calendar packages.
  • Your project cannot provide Tailwind theme tokens, registry aliases, and the shared class-name utility.
  • You require an accessibility-clean default without first correcting the measured color-contrast issue.
  • You need date-range selection from this exact component rather than adapting its underlying calendar exports.

In a non-shadcn project, add React Aria Components, the internationalized date package, and Lucide React. Copy the Origin UI calendar and date-field files, provide the shared class-name merge utility, translate the registry aliases, and define the Tailwind theme tokens and animation utilities used by the classes. Review muted foreground colors for accessible contrast.
