Calendar

import * as React from "react"
import { Calendar } from "@/components/ui/calendar"

function SingleCalendar(props: React.ComponentProps<typeof Calendar>) {
  const today = new Date()
  const [date, setDate] = React.useState<Date | undefined>(
    new Date(today.getFullYear(), today.getMonth(), today.getDate() + 3)
  )
  return (
    <Calendar
      {...props}
      mode="single"
      selected={date}
      onSelect={setDate}
      className="rounded-2xl border"
    />
  )
}

export default function CalendarDemo() {
  return <SingleCalendar buttonVariant="plain" />
}

Calendar is a styled wrapper around DayPicker from react-day-picker, so it accepts the full DayPicker API, including mode, selected, onSelect, numberOfMonths, captionLayout, disabled and showWeekNumber. It replaces the day cells with CalendarDayButton, which renders each day as a Button and styles today, single selections and range start, middle and end.

Use a calendar when people need to see dates in context, such as availability or a stay range. Place it inside a Popover to build a compact date picker; the calendar's background becomes transparent inside popover and card content.

Installation

CLI

$ pnpm dlx shadcn@latest add @esuiss/calendar

Works in any project with a components.json. See Installation for the one-line registry setup. Or use the suiss/ui CLI:

$ pnpm dlx @esuiss/ui@latest add calendar

Manual

Install the dependencies and add the cn helper:

$ pnpm add @phosphor-icons/react react-day-picker

Add the pieces it builds on: Button.
Copy the source into components/ui/calendar.tsx:

components/ui/calendar.tsx

"use client"

import {
  CaretDownIcon,
  CaretLeftIcon,
  CaretRightIcon,
} from "@phosphor-icons/react"
import * as React from "react"
import {
  type ChevronProps,
  type DayButtonProps,
  DayPicker,
  getDefaultClassNames,
  type RootProps,
  useDayPicker,
  type WeekNumberProps,

Update the import paths to match your project.

Usage

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

<SingleCalendar buttonVariant="plain" />

Set mode to single, multiple or range, and control the selection with selected and onSelect. For ranges, numberOfMonths={2} shows two months side by side on wider screens.

Set captionLayout to dropdown, dropdown-months or dropdown-years to let people jump to a month or year directly; the default is label.

Unlike the DayPicker default, outside days are hidden unless you pass showOutsideDays. The default locale is enUS. Pass disabled with a matcher, such as { dayOfWeek: [0, 6] }, to block days.

Use CalendarDayButton when you supply your own components and still want the library's day styling.

Examples

Sizes

Compares the sm, default and lg sizes.

import * as React from "react"
import { Calendar } from "@/components/ui/calendar"

function SingleCalendar(props: React.ComponentProps<typeof Calendar>) {
  const today = new Date()
  const [date, setDate] = React.useState<Date | undefined>(
    new Date(today.getFullYear(), today.getMonth(), today.getDate() + 3)
  )
  return (
    <Calendar
      {...props}
      mode="single"
      selected={date}
      onSelect={setDate}
      className="rounded-2xl border"
    />
  )
}

export default function CalendarSizes() {
  return (
    <div className="flex flex-wrap items-start gap-6">
      <SingleCalendar buttonVariant="plain" size="sm" />
      <SingleCalendar buttonVariant="plain" size="default" />
      <SingleCalendar buttonVariant="plain" size="lg" />
    </div>
  )
}

Range

Selects a seven-day range across two months with mode="range".

import * as React from "react"
import type { DateRange } from "react-day-picker"
import { Calendar } from "@/components/ui/calendar"

function RangeCalendar(props: React.ComponentProps<typeof Calendar>) {
  const today = new Date()
  const [range, setRange] = React.useState<DateRange | undefined>({
    from: today,
    to: new Date(today.getFullYear(), today.getMonth(), today.getDate() + 6),
  })
  return (
    <Calendar
      {...props}
      mode="range"
      selected={range}
      onSelect={setRange}
      numberOfMonths={2}
      className="rounded-2xl border"
    />
  )
}

export default function CalendarRange() {
  return <RangeCalendar buttonVariant="plain" />
}

Replaces the month label with month and year dropdowns.

import * as React from "react"
import { Calendar } from "@/components/ui/calendar"

function SingleCalendar(props: React.ComponentProps<typeof Calendar>) {
  const today = new Date()
  const [date, setDate] = React.useState<Date | undefined>(
    new Date(today.getFullYear(), today.getMonth(), today.getDate() + 3)
  )
  return (
    <Calendar
      {...props}
      mode="single"
      selected={date}
      onSelect={setDate}
      className="rounded-2xl border"
    />
  )
}

export default function CalendarDropdownCaption() {
  return <SingleCalendar buttonVariant="plain" captionLayout="dropdown" />
}

Week numbers

Shows the week number at the start of each row.

import * as React from "react"
import { Calendar } from "@/components/ui/calendar"

function SingleCalendar(props: React.ComponentProps<typeof Calendar>) {
  const today = new Date()
  const [date, setDate] = React.useState<Date | undefined>(
    new Date(today.getFullYear(), today.getMonth(), today.getDate() + 3)
  )
  return (
    <Calendar
      {...props}
      mode="single"
      selected={date}
      onSelect={setDate}
      className="rounded-2xl border"
    />
  )
}

export default function CalendarWeekNumbers() {
  return <SingleCalendar buttonVariant="plain" showWeekNumber />
}

Disabled days

Disables weekends with a dayOfWeek matcher.

import * as React from "react"
import { Calendar } from "@/components/ui/calendar"

function SingleCalendar(props: React.ComponentProps<typeof Calendar>) {
  const today = new Date()
  const [date, setDate] = React.useState<Date | undefined>(
    new Date(today.getFullYear(), today.getMonth(), today.getDate() + 3)
  )
  return (
    <Calendar
      {...props}
      mode="single"
      selected={date}
      onSelect={setDate}
      className="rounded-2xl border"
    />
  )
}

export default function CalendarDisabledDays() {
  return (
    <SingleCalendar buttonVariant="plain" disabled={{ dayOfWeek: [0, 6] }} />
  )
}

API Reference

Calendar

The date grid, with month navigation and caption.

Prop	Type	Default	Description
`buttonVariant`	`React.ComponentProps<typeof Button>["variant"]`	`"plain"`	`Button` variant used for the previous and next month buttons. Defaults to `plain`.
`size`	`"sm" \| "default" \| "lg"`	`"default"`	Cell size and type scale: `sm`, `default` or `lg`.

Also accepts the props of React.ComponentProps<typeof DayPicker>.

CalendarDayButton

The button rendered for each day, styled by its selection state.

Also accepts the props of DayButtonProps.

Accessibility

Each month renders as a grid labelled with its month and year; selected days set aria-selected on their cell.
Arrow keys move focus between days, and clicking or pressing a day selects it.
The navigation buttons are labelled for the next and previous month.
Disabled days render disabled buttons.
Caption dropdowns are native select elements labelled for month and year.

Notes

Styling hooks: data-slot="calendar" and data-size on the root; day buttons expose data-day, data-today, data-selected-single, data-range-start, data-range-middle and data-range-end.
Cell size and radius come from the --cell-size and --cell-radius custom properties, which size adjusts.
Pass classNames to override any react-day-picker class key; your values replace the defaults for that key.
Navigation chevrons flip in right-to-left layouts.

Calendar renders one or more month grids with a caption, previous and next buttons, weekday headers and pressable day cells. Selection mode is set with mode: single, multiple or range. Ranges are drawn as a continuous shaded band with filled start and end days.

Three sizes are available: sm, default and lg. The caption can be a plain label or month and year dropdowns built on Select, which suits birth dates and other dates far from today.

Usage

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

<SingleCalendar />

Pass mode, selected and onSelect to control the selection; selected is a Date, a Date[] or a { from, to } range depending on the mode. Use month, defaultMonth and onMonthChange to control the visible month, and numberOfMonths to show several months.

Use disabled with date matchers, such as { dayOfWeek: [0, 6] }, to block days. Limit navigation with startMonth and endMonth; with a year dropdown they default to the last 100 years.

Set locale for month and weekday names, and weekStartsOn to change the first day of the week. CalendarDayButton is exported for custom day rendering.

Examples

Sizes

The sm, default and lg sizes.

API Reference

CalendarDayButton

Pressable day cell styled for each selection state.

Also accepts the props of React.ComponentProps<typeof CalendarPrimitive.DayButton>.

Calendar

Month grids with caption and navigation.

Prop	Type	Default	Description
`buttonVariant`	`ButtonProps["variant"]`	`"plain"`	Button variant for the navigation buttons. Defaults to `plain`.
`size`	`CalendarSize`	`"default"`	`sm`, `default` or `lg`.
`captionLayout`	`CaptionLayout`	`"label"`	`label`, `dropdown`, `dropdown-months` or `dropdown-years`.
`showWeekNumber`	`boolean`	`false`	Shows week numbers.

Also accepts the props of React.ComponentProps<typeof CalendarPrimitive.Root>.

Accessibility

Each month is a grid labelled with its caption.
Day cells have the button role, a full date label, and selected and disabled state.
On React Native and Android, the previous and next buttons are labelled with the relative month in the calendar's locale, such as "Last month" and "Next month" in English. On iOS they are labelled "Previous month" and "Next month".
Caption dropdowns are labelled "Choose the Month" and "Choose the Year".

Notes

Navigation arrows swap in right-to-left layouts.
Uses bg-primary, bg-primary/10 dark:bg-primary/20, bg-muted and text-primary tokens; light and dark follow the system appearance.
