Calendar

A calendar consists of a grouping element containing one or more date grids (e.g. months), and a previous and next button for navigating between date ranges. Each calendar grid consists of cells containing button elements that can be pressed and navigated to using the arrow keys to select a date.

Installation

npx nextui-cli@latest add calendar

No need to install this package if @nextui-org/react is already installed globally.

Import

Usage

A Calendar has no selection by default. An initial, uncontrolled value can be provided to the Calendar using the defaultValue prop. Alternatively, a controlled value can be provided using the value prop.

Date values are provided using objects in the @internationalized/date package. This library handles correct international date manipulation across calendars, time zones, and other localization concerns.

Disabled

The isDisabled boolean prop makes the Calendar disabled. Cells cannot be focused or selected.

Read Only

The isReadOnly boolean prop makes the Calendar's value immutable. Unlike isDisabled, the Calendar remains focusable.

Controlled

A Calendar has no selection by default. An initial, uncontrolled value can be provided to the Calendar using the defaultValue prop. Alternatively, a controlled value can be provided using the value prop.

Min Date Value

By default, Calendar allows selecting any date. The minValue can also be used to prevent the user from selecting dates outside a certain range.

This example only accepts dates after today.

Max Date Value

By default, Calendar allows selecting any date. The maxValue can also be used to prevent the user from selecting dates outside a certain range.

This example only accepts dates before today.

Unavailable Dates

Calendar supports marking certain dates as unavailable. These dates remain focusable with the keyboard so that navigation is consistent, but cannot be selected by the user. In this example, they are displayed in red. The isDateUnavailable prop accepts a callback that is called to evaluate whether each visible date is unavailable.

Controlled Focused Value

Calendar tries to avoid allowing the user to select invalid dates in the first place. However, if according to application logic a selected date is invalid, the isInvalid prop can be set. This alerts assistive technology users that the selection is invalid, and can be used for styling purposes as well. In addition, the errorMessage slot may be used to help the user fix the issue.

By default, the selected date is focused when a Calendar first mounts. If no value or defaultValue prop is provided, then the current date is focused. However, Calendar supports controlling which date is focused using the focusedValue and onFocusChange props. This also determines which month is visible. The defaultFocusedValue prop allows setting the initial focused date when the Calendar first mounts, without controlling it.

Invalid Date

This example validates that the selected date is a weekday and not a weekend according to the current locale.

With Month And Year Picker

Calendar supports month and year picker for rapid selection.

International Calendars

Calendar supports selecting dates in many calendar systems used around the world, including Gregorian, Hebrew, Indian, Islamic, Buddhist, and more. Dates are automatically displayed in the appropriate calendar system for the user's locale. The calendar system can be overridden using the Unicode calendar locale extension, passed to the Provider component.

Visible Months

By default, the Calendar displays a single month. The visibleMonths prop allows displaying up to 3 months at a time.

Page Behaviour

By default, when pressing the next or previous buttons, pagination will advance by the visibleMonths value. This behavior can be changed to page by single months instead, by setting pageBehavior to single.

• data-unavailable: Whether the cell is unavailable, according to the calendar's isDateUnavailable prop. Unavailable dates remain focusable, but cannot be selected by the user.
