The Calendar allows you to disable certain days which are not intended to be selected by the end user—for example, weekends, national holidays, and others.
To disable a date, either:
When you set an array, list the days that need to be disabled by using the first letters from their names in English.
<kendo-calendar :disable-dates='["we", "th"]'></kendo-calendar>
When you add a function, determine its return value as
true for the date that is disabled.
