Hello Janos,

The workaround was initially provided for the DatePicker, which provides topView and bottomView properties that control the selection depth:

https://www.telerik.com/kendo-angular-ui/components/dateinputs/datepicker/calendar-options#view-selection-depth

Unfortunately, the DateTimePicker component does not provide topView and bottomView properties. However, the [disabledDates]="isDateDisabled" works the same. In your case, the disabled dates are only those whose month is June (5). 

  public isDateDisabled(date: Date): boolean {
    return date.getMonth() === 5;
  }

In the template, you are just visually making the date disabled.

You need to adjust the logic in isDateDisabled in order to disable the desired dates, considering the fact that the selection depth cannot be controlled in the DateTimePicker.

Hi,

The feature request for disabling months and years in the Calendar is still not part of our immediate development plans, and we are still monitoring the demand for it. On that note, I would suggest following the item to stay notified of any updates on its implementation.

For the time being, as a potential workaround, the developer can combine the disabledDates callback with the kendoCalendarYearCellTemplate directive (or kendoCalendarDecadeCellTemplate respectively) and apply suitable styles to the specific month cell to disable it:

Such an approach is also demonstrated in the following Knowledge Base article:

• https://www.telerik.com/kendo-angular-ui/components/knowledge-base/disabled-month-view

Alternatively, if the feature is urgent for your project, an option that may be relevant and applicable to your needs is the Feature Acceleration program. This program fits well in scenarios where a feature or enhancement is important for an application's success, but it is not planned to be available at the time of the application's completion. Let me know if you are interested in pursuing this option.
