JQuery UI Datepicker - MaxDate exclude disabled days

I am trying to exclude disabled dates when counting MaxDate. I tried many ways but still doesn't work. Any suggestion?

02-12-2019 and Sundays has been disabled but the Maxdate include the disabled date. Maxdate should be 3 days which excludes disabled days and Maxdays starts by today. My goal is to add days if the days between today until max days has disabled. Add 1 day per disabled day

Update

Now i am able to Exclude sunday when counting maxdate but i still can't exclude the array date where it should add one more day after 02-12-2019.

Updated Code :(

<script>
var array = ["02-12-2019"]

//new

function includeDate(date) {

    return date.getDay() !== 7 && date.getDay() !== 0;
}

function getTomorrow(date) {
    return new Date(date.getFullYear(), date.getMonth(), date.getDate() + 1);
}

//prev

    $('input').datepicker(
        {
      defaultDate: "+1d",
      inline: true,
      showOtherMonths: true,
      changeMonth: true,
      selectOtherMonths: true,
      required: true,
      showOn: "focus",
      numberOfMonths: 1,
      minDate: 1,
    beforeShowDay: function(date) {
        var string = jQuery.datepicker.formatDate('dd-mm-yy', date);
         var isDisabled = ($.inArray(string, array) != -1);
        return [includeDate(date)  && !isDisabled];
    },

    maxDate: (function(max) {
        var today = new Date();
        var nextAvailable = getTomorrow(today);
        var count = 0;
        var countz = 1;
        var newMax = 0;
        while(count < max) {
            if (includeDate(nextAvailable) ) {
                count++;
            }
            if (includeDate(nextAvailable) ) {
                countz++;
            }
            newMax++;
            nextAvailable = getTomorrow(nextAvailable);            
        }
        return newMax;
    })
    (3)
    });
