# Calendar Documentation Displays dates and days of the week, facilitating date-related interactions. This is a documentation section that potentially contains examples, demos, and other useful information related to a specific part of Bits UI. When helping users with this documentation, you can ignore the classnames applied to the demos unless they are relevant to the user's issue. Copy Page ```svelte {#snippet children({ months, weekdays })}

{#each months as month, i (i)} {#each weekdays as day, i (i)}

{day.slice(0, 2)}

{/each} {#each month.weeks as weekDates, i (i)} {#each weekDates as date, i (i)} {date.day} {/each} {/each} {/each}

{/snippet} ``` ##### Heads up! Before diving into this component, it's important to understand how dates/times work in Bits UI. Please read the [Dates](/docs/dates) documentation to learn more! ## Structure ```svelte {#snippet children({ months, weekdays })} {#each months as month} {#each weekdays as day} {day} {/each} {#each month.weeks as weekDates} {#each weekDates as date} {/each} {/each} {/each} {/snippet} ``` ## Placeholder The `placeholder` prop for the `Calendar.Root` component determines what date our calendar should start with when the user hasn't selected a date yet. It also determines the current "view" of the calendar. As the user navigates through the calendar, the `placeholder` will be updated to reflect the currently focused date in that view. By default, the `placeholder` will be set to the current date, and be of type `CalendarDate`. ## Managing Placeholder State This section covers how to manage the `placeholder` state of the Calendar. ### Two-Way Binding Use `bind:placeholder` for simple, automatic state synchronization: ```svelte ``` ### Fully Controlled Use a [Function Binding](https://svelte.dev/docs/svelte/bind#Function-bindings) for complete control over the state's reads and writes. ```svelte ``` See the [State Management](/docs/state-management) documentation for more information. ## Managing Value State This section covers how to manage the `value` state of the Calendar. ### Two-Way Binding Use `bind:value` for simple, automatic state synchronization: ```svelte ``` ### Fully Controlled Use a [Function Binding](https://svelte.dev/docs/svelte/bind#Function-bindings) for complete control over the state's reads and writes. ```svelte ``` See the [State Management](/docs/state-management) documentation for more information. ## Default Value Often, you'll want to start the `Calendar.Root` component with a default value. Likely this value will come from a database in the format of an ISO 8601 string. You can use the `parseDate` function from the `@internationalized/date` package to parse the string into a `CalendarDate` object. ```svelte ``` ## Validation ### Minimum Value You can set a minimum value for the calendar by using the `minValue` prop on `Calendar.Root`. If a user selects a date that is less than the minimum value, the calendar will be marked as invalid. ```svelte ``` ### Maximum Value You can set a maximum value for the calendar by using the `maxValue` prop on `Calendar.Root`. If a user selects a date that is greater than the maximum value, the calendar will be marked as invalid. ```svelte ``` ### Unavailable Dates You can specify specific dates that are unavailable for selection by using the `isDateUnavailable` prop. This prop accepts a function that returns a boolean value indicating whether a date is unavailable or not. ```svelte ``` ### Disabled Dates You can specify specific dates that are disabled for selection by using the `isDateDisabled` prop. ```svelte ``` ### Max Days You can set the `maxDays` prop to limit the maximum number of days that can be selected when the calendar is `'multiple'` type. ```svelte ``` Expand Code ```svelte {#snippet children({ months, weekdays })}

{#each months as month, i (i)} {#each weekdays as day, i (i)}

{day.slice(0, 2)}

{/each} {#each month.weeks as weekDates, i (i)} {#each weekDates as date, i (i)} {date.day} {/each} {/each} {/each}

{/snippet} ``` ## Appearance & Behavior ### Fixed Weeks You can use the `fixedWeeks` prop to ensure that the calendar renders a fixed number of weeks, regardless of the number of days in the month. This is useful to keep the calendar visually consistent when the number of days in the month changes. ```svelte ``` ### Multiple Months You can use the `numberOfMonths` prop to render multiple months at once. ```svelte ``` ### Paged Navigation By default, when the calendar has more than one month, the previous and next buttons will shift the calendar forward or backward by one month. However, you can change this behavior by setting the `pagedNavigation` prop to `true`, which will shift the calendar forward or backward by the number of months being displayed. ```svelte ``` ### Localization The calendar will automatically format the content of the calendar according to the `locale` prop, which defaults to `'en-US'`, but can be changed to any locale supported by the [`Intl.DateTimeFormat`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/DateTimeFormat) API. ```svelte ``` ### Week Starts On The calendar will automatically format the content of the calendar according to the `locale`, which will determine what day of the week is the first day of the week. You can also override this by setting the `weekStartsOn` prop, where `0` is Sunday and `6` is Saturday to force a consistent first day of the week across all locales. ```svelte ``` ### Multiple Selection You can set the `type` prop to `'multiple'` to allow users to select multiple dates at once. ```svelte ``` ## Custom Composition ### Month Selector The `Calendar` component includes a `PrevButton` and `NextButton` component to allow users to navigate between months. This is useful, but sometimes you may want to allow the user to select a specific month from a list of months, rather than having to navigate one at a time. To achieve this, you can use the `placeholder` prop to set the month of the the calendar view programmatically. ```svelte ``` Updating the `placeholder` will update the calendar view to reflect the new month. ## Examples ### Month and Year Selects This example demonstrates how to use the `placeholder` prop to set the month and year of the calendar view programmatically. Expand Code ```svelte {#snippet children({ months, weekdays })}

{#each months as month, i (i)} {#each weekdays as day, i (i)}

{day.slice(0, 2)}

{/each} {#each month.weeks as weekDates, i (i)} {#each weekDates as date, i (i)} {date.day} {/each} {/each} {/each}

{/snippet} ``` ### Preset Dates This example demonstrates how to programatically set the `value` of the calendar to a specific date when a user presses a button. Expand Code ```svelte

{#snippet children({ months, weekdays })}

{#each months as month, i (i)} {#each weekdays as day, i (i)}

{day.slice(0, 2)}

{/each} {#each month.weeks as weekDates, i (i)} {#each weekDates as date, i (i)} {date.day} {/each} {/each} {/each}

{/snippet}

{#each presets as preset (preset.label)} {preset.label} {/each}
