Calendar Accessibility

Out of the box, the Kendo UI for Vue Calendar provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.

The Calendar is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 AA standards](https://www.w3.org/TR/WCAG22/) and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the keyboard navigation for its component role, provides options for managing its focus and is tested against the most popular screen readers.

This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.
