When the selectionVariant prop is set to "single", the Calendar component allows users to select only a single date, providing a straightforward and focused date selection experience.

When the selectionVariant prop is set to "range", the Calendar component allows users to select a date range, including both a start date and an end date, enabling a comprehensive date selection experience.

When the selectionVariant prop is set to "multiselect", the Calendar component allows users to select multiple individual dates, providing flexibility for selecting non-consecutive dates.

When the selectionVariant prop is set to "offset", the Calendar component allows users to select a date range by choosing a single start date, with the end date automatically determined based on a predefined offset.

Unselectable dates are visually distinct from selectable dates. When a user attempts to select an unselectable date, the calendar displays a tooltip with additional information. To implement this, use the isDayUnselectable prop to pass a function that determines whether a day is unselectable and provides the tooltip description.

Disabled dates are not selectable. To implement this, use the isDayUnselectable prop to pass a function that determines whether a day is unselectable and provides the tooltip description.

Highlighted dates are marked by a triangle in the top right corner, indicating an event associated with that day. When a user hovers over a highlighted date, the calendar displays a tooltip with additional information. To implement this, use the isDayHighlighted prop to pass a function that determines whether a day is highlighted and provides the tooltip description.

To customize the rendering of a day element, use the renderDayContents prop with the Calendar component. This prop accepts a function that is passed a DateValue and returns the custom element for that day. This can be useful for scenarios where you need to display additional information or apply custom styling to specific dates.

By default, dates outside the visible month are out-of-range and visually distinct from the current month's dates. To hide these out-of-range dates, use the hideOutOfRangeDates prop.

To hide the year dropdown, use the hideYearDropdown prop with the CalendarNavigation component. This can be useful in scenarios such as when the calendar is composed with other calendars or when the date selection does not require a year.

To constrain the selected date within a specific range, use the minDate and/or maxDate props. If minDate is not provided, it defaults to the year 1900. If maxDate is undefined, it defaults to the year 2100. This ensures that the selected date remains within the specified range.

A Calendar component with a border provides a visually distinct area for selecting dates, enhancing the user interface by clearly delineating the calendar boundaries. This styling can improve usability and accessibility by making the calendar controls more noticeable and easier to interact with.

The Twin Calendars example demonstrates how to use the Calendar component with the minDate and maxDate props to create an effective date range picker. By configuring two Calendar components side by side, users can easily select a start date and an end date within a specified range.

When the locale prop is provided, the Calendar component uses it to define the calendar's locale, ensuring that date formats, month names, and other locale-specific elements are displayed according to the specified locale.

When the children prop is used, the Calendar component allows consumers to customize the calendar header, typically by composing it with the CalendarNavigation component for forward/back month controls and month/year dropdowns, but it can also be used to add additional controls such as a 'Today' button.
