The Web accessibility defines a way to make web content and web applications more accessible to disabled people. It especially helps the dynamic content change and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies.
Calendar provides built-in compliance with the WAI-ARIA specifications. WAI-ARIA support is achieved through the attributes like aria-label,aria-selected, aria-disabled, aria-activedescendant applied for navigation buttons, disabled and active day cells.
It helps to provide the information about the widget for assistive technology to the disabled person in the screen reader. The Calendar component uses role=grid and gridcell for each day cell.
The following table lists the WAI-ARIA attributes and roles applied to the Calendar component.
| Attribute / Role | Description |
|---|---|
aria-label |
Provides the text label for the previous and next month navigation elements. It enables screen readers to announce the element. |
aria-selected |
Indicates the currently selected date of the Calendar component. |
aria-disabled |
Indicates the disabled state of the Calendar component. |
aria-activedescendant |
Helps in managing the current active child of the Calendar component. |
role=grid |
Gives assistive technologies information about how to handle the Calendar container element. |
gridcell |
Defines the individual day cell that can be focusable and selectable. |
A sample of the rendered WAI-ARIA structure is shown below.
<div role="grid" aria-label="Calendar">
<div role="presentation">
<button aria-label="Previous month">‹</button>
<span aria-label="January 2026">January 2026</span>

</div>
<div role="row">
<div class="e-day" role="gridcell" aria-selected="true">1</div>
