Markdown: https://hextaui.com/docs/calendar.md

```tsx title="components/examples/calendar/demo.tsx"
"use client"

import * as React from "react"
import { format } from "date-fns"

import { Calendar } from "@/components/ui/calendar"

export function CalendarDemo() {
  const [date, setDate] = React.useState<Date>()

  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar
        mode="single"
        selected={date}
        onSelect={setDate}
        footer={date ? `Selected ${format(date, "PPP")}.` : "Pick a day."}
      />
    </div>
  )
}
```

## Installation

### CLI

```bash
npx shadcn@latest add https://hextaui.com/r/calendar.json
```

This adds the component, the HextaUI theme tokens and any HextaUI components it depends on.

### Manual

Add the HextaUI theme tokens (https://hextaui.com/docs/installation#theme) to your global CSS if you haven't yet, then install the dependencies.

```bash
pnpm add react-day-picker @base-ui/react @tabler/icons-react class-variance-authority cn
```

Copy and paste the following code into your project.

## Usage

```tsx
import { Calendar } from "@/components/ui/calendar"
```

```tsx
const [date, setDate] = React.useState<Date>()

<Calendar mode="single" selected={date} onSelect={setDate} />
```

Calendar wraps react-day-picker’s `<DayPicker />`, so every DayPicker prop works as documented on daypicker.dev. HextaUI adds styling, month transitions, a range preview and a hydration-safe today.

## Examples

### Range

With `mode="range"`, after the first click hovering or focusing a day previews the range the next click will select. `numberOfMonths` shows months side by side, stacked on narrow screens.

```tsx title="components/examples/calendar/range.tsx"
"use client"

import * as React from "react"
import { format } from "date-fns"
import type { DateRange } from "react-day-picker"

import { Calendar } from "@/components/ui/calendar"

export function CalendarRange() {
  const [range, setRange] = React.useState<DateRange>()

  return (
    <div className="max-w-full overflow-x-auto rounded-xl border">
      <Calendar
        mode="range"
        numberOfMonths={2}
        selected={range}
        onSelect={setRange}
        footer={
          range?.from && range.to
            ? `${format(range.from, "PP")} – ${format(range.to, "PP")}`
            : range?.from
              ? "Pick an end date."
              : "Pick a start date."
        }
      />
    </div>
  )
}
```

### Range limits

`min` and `max` limit the range length in days. With `excludeDisabled`, a range that would include a disabled day starts over instead.

```tsx title="components/examples/calendar/range-limits.tsx"
import { Calendar } from "@/components/ui/calendar"

export function CalendarRangeLimits() {
  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar
        mode="range"
        min={2}
        max={7}
        disabled={{ dayOfWeek: [0, 6] }}
        excludeDisabled
        footer="Weekdays only, 2–7 days."
      />
    </div>
  )
}
```

### Multiple

`mode="multiple"` toggles individual days. `max` caps how many can be selected.

```tsx title="components/examples/calendar/multiple.tsx"
import { Calendar } from "@/components/ui/calendar"

export function CalendarMultiple() {
  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar mode="multiple" max={5} footer="Pick up to five days." />
    </div>
  )
}
```

### Month and year dropdowns

`captionLayout="dropdown"` replaces the caption with native selects, so phones get their own picker. Set `startMonth` and `endMonth` to bound the years.

```tsx title="components/examples/calendar/dropdowns.tsx"
import { Calendar } from "@/components/ui/calendar"

export function CalendarDropdowns() {
  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar
        mode="single"
        captionLayout="dropdown"
        startMonth={new Date(1940, 0)}
        endMonth={new Date(2035, 11)}
        defaultMonth={new Date(1995, 5)}
      />
    </div>
  )
}
```

### Bounded

Navigation stops at `startMonth` and `endMonth`, and `disabled` blocks days outside the window. `useToday()` gives a today that is safe to use during server rendering.

```tsx title="components/examples/calendar/bounded.tsx"
"use client"

import { addDays, startOfMonth } from "date-fns"

import { Calendar } from "@/components/ui/calendar"
import { useToday } from "@/hooks/use-today"

export function CalendarBounded() {
  const today = useToday()
  const last = today && addDays(today, 45)

  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar
        mode="single"
        startMonth={today && startOfMonth(today)}
        endMonth={last && startOfMonth(last)}
        disabled={
          today && last ? [{ before: today }, { after: last }] : undefined
        }
        footer="Bookable for the next 45 days."
      />
    </div>
  )
}
```

### Controlled month

Pass `month` and `onMonthChange` to drive the visible month. Jumps slide in the direction of travel and the height eases between 5 and 6 week rows.

```tsx title="components/examples/calendar/controlled.tsx"
"use client"

import * as React from "react"

import { Button } from "@/components/ui/button"
import { Calendar } from "@/components/ui/calendar"
import { useToday } from "@/hooks/use-today"

export function CalendarControlled() {
  const today = useToday()
  const [month, setMonth] = React.useState<Date>()
  const [date, setDate] = React.useState<Date>()
  const shown = month ?? today

  return (
    <div className="flex max-w-full min-w-0 flex-col items-center gap-3">
      <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
        <Calendar
          mode="single"
          month={shown}
          onMonthChange={setMonth}
          selected={date}
          onSelect={setDate}
        />
      </div>
      <div className="flex gap-2">
        <Button
          variant="outline"
          size="sm"
          onClick={() => {
            const now = new Date()
            setMonth(now)
            setDate(now)
          }}
        >
          Today
        </Button>
        <Button
          variant="outline"
          size="sm"
          onClick={() => {
            const base = shown ?? new Date()
            setMonth(new Date(base.getFullYear() + 1, base.getMonth()))
          }}
        >
          Next year
        </Button>
      </div>
    </div>
  )
}
```

### Week numbers

`showWeekNumber` adds a week column. `ISOWeek` uses ISO numbering, starting on Monday. `showOutsideDays={false}` hides days of other months.

```tsx title="components/examples/calendar/week-numbers.tsx"
import { Calendar } from "@/components/ui/calendar"

export function CalendarWeekNumbers() {
  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar mode="range" showWeekNumber ISOWeek showOutsideDays={false} />
    </div>
  )
}
```

### Fixed today

Pass `today` to pin the highlighted day, for tests or another time zone. `animate={false}` turns off month transitions.

```tsx title="components/examples/calendar/fixed-today.tsx"
"use client"

import * as React from "react"
import type { DateRange } from "react-day-picker"

import { Calendar } from "@/components/ui/calendar"

export function CalendarFixedToday() {
  const [range, setRange] = React.useState<DateRange | undefined>({
    from: new Date(2026, 1, 9),
    to: new Date(2026, 1, 17),
  })

  return (
    <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
      <Calendar
        mode="range"
        today={new Date(2026, 1, 11)}
        defaultMonth={new Date(2026, 1)}
        selected={range}
        onSelect={setRange}
        animate={false}
      />
    </div>
  )
}
```

### Inside a sheet

Inside a sheet, popover or dialog the calendar drops its own background and blends with the surface.

```tsx title="components/examples/calendar/sheet.tsx"
"use client"

import * as React from "react"
import { format } from "date-fns"

import { Button } from "@/components/ui/button"
import { Calendar } from "@/components/ui/calendar"
import {
  Sheet,
  SheetBody,
  SheetContent,
  SheetDescription,
  SheetHeader,
  SheetTitle,
  SheetTrigger,
} from "@/components/ui/sheet"

export function CalendarSheet() {
  const [date, setDate] = React.useState<Date>()

  return (
    <Sheet>
      <SheetTrigger render={<Button variant="outline" />}>
        {date ? format(date, "PPP") : "Choose a date"}
      </SheetTrigger>
      <SheetContent>
        <SheetHeader>
          <SheetTitle>Schedule</SheetTitle>
          <SheetDescription>Pick a delivery day.</SheetDescription>
        </SheetHeader>
        <SheetBody>
          <Calendar mode="single" selected={date} onSelect={setDate} />
        </SheetBody>
      </SheetContent>
    </Sheet>
  )
}
```

### Right to left

Pass a `locale` from `react-day-picker/locale` and `dir="rtl"`. Arrows, navigation and the slide direction all mirror. Inside a `dir="rtl"` DirectionProvider, the direction is picked up automatically.

```tsx title="components/examples/calendar/rtl.tsx"
"use client"

import { arSA } from "react-day-picker/locale"

import { Calendar } from "@/components/ui/calendar"

export function CalendarRtl() {
  return (
    <div dir="rtl" className="max-w-full min-w-0">
      <div className="w-fit max-w-full overflow-x-auto rounded-xl border">
        <Calendar mode="range" locale={arSA} dir="rtl" />
      </div>
    </div>
  )
}
```

## Keyboard

Focus a day, then use these keys. Moving past the visible month changes the month.

| Key | Action |
| --- | --- |
| `←` `→` | Previous or next day. Reversed in right-to-left layouts. |
| `↑` `↓` | Same day of the previous or next week. |
| `Shift` `←` `→` | Previous or next month. |
| `Shift` `↑` `↓` | Previous or next year. |
| `Page Up` `Page Down` | Previous or next month. |
| `Shift` `Page Up` `Page Down` | Previous or next year. |
| `Home` | First day of the week. |
| `End` | Last day of the week. |
| `Enter` `Space` | Selects the focused day. |

## Accessibility

- The month is a grid. Each day is a button with a full date label, and selected days set `aria-selected`.
- Month changes made with the keyboard skip the slide and only fade, so focus never moves under a moving grid.
- With reduced motion, month changes fade and the height change is instant.
- On touch screens the day cells grow to 44px.

### useToday

Returns today as a `Date` on the client and `undefined` during server rendering, so bounds built from it never cause a hydration mismatch. It updates at midnight. See the [useToday guide](https://hextaui.com/docs/use-today).

## Notes for AI assistants

- Install a component with the shadcn CLI: `npx shadcn@latest add https://hextaui.com/r/<name>.json`. It adds the source, the HextaUI theme tokens and any HextaUI components it depends on. `https://hextaui.com/r/all.json` installs every component.
- The code is then owned by the project, like shadcn/ui. There is no HextaUI npm package. HextaUI is MIT licensed and free for personal and commercial use.
- Behavior and accessibility come from Base UI (`@base-ui/react`). Compose with the `render` prop, not `asChild`.
- Styling uses Tailwind CSS v4 with theme tokens. Merge classes with `cn` from the `cn` package.
- Icons come from `@tabler/icons-react`.
- Import components from `@/components/ui/<name>`, hooks from `@/hooks/<name>` and utilities from `@/lib/<name>`.
