  var string = jQuery.datepicker.formatDate('mm-dd-yy', date);
  return [(day != 1 && day != 2) && array.indexOf(string) == -1];
},

On the third line, April 8th, April 9th, and April 10th are blocked out. If you would like to add more dates, follow the example in the second snippet below.

var array = ["04-08-2020", "04-09-2020", "04-10-2020"];

On the fifth line, Monday and Tuesday are blocked out. If you would like to block out more days of the week (Sunday = 0, Monday = 1, Tuesday = 2, Wednesday = 3, Thursday = 4, Friday = 5, Saturday = 6), follow the example in the second snippet below.

return [(day != 1 && day != 2) && array.indexOf(string) == -1];
return [(day != 0 && day != 1 && day != 2 && day != 3 && day != 4 && day != 5 && day != 6) && array.indexOf(string) == -1];

Block out specific days of the week

  var day = date.getDay();
  return [(day != 1 && day != 2)];
},
beforeShowDay: function(date) {

  return [(day != 0 && day != 1 && day != 2 && day != 3 && day != 4 && day != 5)];
