Installation

pnpm dlx shadcn@latest add @kibo-ui/calendar

Usage

usage.tsx
import {  CalendarBody,  CalendarDate,  CalendarDatePagination,  CalendarHeader,  CalendarItem,  CalendarMonthPicker,  CalendarProvider,  CalendarYearPicker,  type Feature,} from "@/components/kibo-ui/calendar";const features: Feature[] = [  {    id: "launch",    name: "Product launch",    startAt: new Date(2025, 0, 6),    endAt: new Date(2025, 0, 15),    status: { id: "in-progress", name: "In progress", color: "#3b82f6" },  },];export function FeatureCalendar() {  return (    <CalendarProvider>      <CalendarDate>        <div className="flex items-center gap-1">          <CalendarMonthPicker />          <CalendarYearPicker start={2024} end={2026} />        </div>        <CalendarDatePagination />      </CalendarDate>      <CalendarHeader />      <CalendarBody features={features}>        {({ feature }) => <CalendarItem feature={feature} />}      </CalendarBody>    </CalendarProvider>  );}
  • Display project features, tasks, milestones, or roadmap items grouped by their end date.
  • Provide month and year navigation with localized month and weekday labels.
  • Use when each calendar day needs custom feature content through a render callback.
  • Compose with shadcn/ui Button, Command, and Popover components in a client-side application.

Examples

Roadmap calendar

Shows roadmap features grouped by their end date with the built-in CalendarItem renderer.

roadmap-calendar.tsx
import {  CalendarBody,  CalendarDate,  CalendarDatePagination,  CalendarHeader,  CalendarItem,  CalendarMonthPicker,  CalendarProvider,  CalendarYearPicker,  type Feature,} from "@/components/kibo-ui/calendar";const roadmap: Feature[] = [  {    id: "api",    name: "API v2",    startAt: new Date(2025, 1, 1),    endAt: new Date(2025, 1, 12),    status: { id: "planned", name: "Planned", color: "#8b5cf6" },  },];export function RoadmapCalendar() {  return (    <CalendarProvider>      <CalendarDate>        <div className="flex items-center gap-1">          <CalendarMonthPicker />          <CalendarYearPicker start={2025} end={2026} />        </div>        <CalendarDatePagination />      </CalendarDate>      <CalendarHeader />      <CalendarBody features={roadmap}>        {({ feature }) => <CalendarItem feature={feature} />}      </CalendarBody>    </CalendarProvider>  );}

Localized Monday-start calendar

Uses a French locale and starts the week on Monday.

localized-monday-start-calendar.tsx
import {  CalendarBody,  CalendarHeader,  CalendarProvider,  type Feature,} from "@/components/kibo-ui/calendar";const features: Feature[] = [];export function LocalizedCalendar() {  return (    <CalendarProvider locale="fr-FR" startDay={1}>      <CalendarHeader />      <CalendarBody features={features}>        {({ feature }) => <span>{feature.name}</span>}      </CalendarBody>    </CalendarProvider>  );}

Custom feature rendering

Renders each feature with custom content instead of CalendarItem.

custom-feature-rendering.tsx
import {  CalendarBody,  CalendarProvider,  type Feature,} from "@/components/kibo-ui/calendar";const features: Feature[] = [];export function CustomFeatureCalendar() {  return (    <CalendarProvider className="rounded-lg border">      <CalendarBody features={features}>        {({ feature }) => (          <div className="truncate rounded bg-primary px-1 text-primary-foreground">            {feature.name}          </div>        )}      </CalendarBody>    </CalendarProvider>  );}

Accessibility

  • Month and year pickers use the underlying shadcn/ui Popover and Command components, including searchable command lists and expanded-state indication on their trigger buttons.
  • Previous and next month controls are actual buttons, but the source does not provide accessible labels or visible text for the icon-only controls; add an accessible name through the underlying button implementation or wrap/augment the component if needed.
  • The calendar is rendered as a visual CSS grid rather than semantic table or grid-cell elements, and it does not provide keyboard navigation or selected-date semantics.
  • Feature status is represented by a color dot and text; ensure custom renderers do not rely on color alone to communicate status.
  • The component is client-only because it uses React state and Jotai atoms.
