# Date Picker

A date picker component with range and presets.

## When to use

* Let the user pick a date from a calendar that opens from a button.
* Pick a range of dates or a date from presets.

## How it works

Date Picker is not a component you install: it is a composition of `Popover` and `Calendar`. The demo opens a `Calendar` in `mode="single"` inside a `Popover`, and formats the date with `date-fns`.

## Example

### Base UI

```tsx
'use client'

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

import { Button } from "@/shadcn/base/ui/button"
import { Calendar } from "@/shadcn/base/ui/calendar"
import {
  Popover,
  PopoverContent,
  PopoverTrigger,
} from "@/shadcn/base/ui/popover"

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

  return (
    <Popover>
      <PopoverTrigger
        render={
          <Button
            variant={"outline"}
            data-empty={!date}
            className="w-[212px] justify-between text-left font-normal data-[empty=true]:text-muted-foreground"
          />
        }
      >
        {date ? format(date, "PPP") : <span>Pick a date</span>}
        <ChevronDownIcon data-icon="inline-end" />
      </PopoverTrigger>
      <PopoverContent className="w-auto p-0" align="start">
        <Calendar
          mode="single"
          selected={date}
          onSelect={setDate}
          defaultMonth={date}
        />
      </PopoverContent>
    </Popover>
  )
}
```

### Radix

```tsx
'use client'

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

import { Button } from "@/shadcn/radix/ui/button"
import { Calendar } from "@/shadcn/radix/ui/calendar"
import {
  Popover,
  PopoverContent,
  PopoverTrigger,
} from "@/shadcn/radix/ui/popover"

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

  return (
    <Popover>
      <PopoverTrigger asChild>
        <Button
          variant="outline"
          data-empty={!date}
          className="w-[212px] justify-between text-left font-normal data-[empty=true]:text-muted-foreground"
        >
          {date ? format(date, "PPP") : <span>Pick a date</span>}
          <ChevronDownIcon />
        </Button>
      </PopoverTrigger>
      <PopoverContent className="w-auto p-0" align="start">
        <Calendar
          mode="single"
          selected={date}
          onSelect={setDate}
          defaultMonth={date}
        />
      </PopoverContent>
    </Popover>
  )
}
```
