What is dateA11yLabel and monthYearA11yLabel in Datepicker in Angular Material?

Asked on July 04, 2020
In Angular Material Datepicker, to set format I need to use following code from
https://material.angular.io/components/datepicker/overview
export const MY_FORMATS = {
parse: {
dateInput: 'LL',
},
display: {
dateInput: 'LL',
monthYearLabel: 'MMM YYYY',
dateA11yLabel: 'LL',
monthYearA11yLabel: 'MMMM YYYY',
},
};

The dateA11yLabel and monthYearA11yLabel is for Accessibility(A11Y).
The Accessibility (a11y) project is community driven effort to make web accessibility easier for the all people including those with disabilities or impairments.
