Using datepicker in jquery to keep start date less than end date and allowing no weekends selection

I am new to jQuery and JSP. I am trying to make a booking system which has two dates - start date and end date. I require the following functionalities to be included in the system.

1. Start date should be less than end date and end date should be more than start date.
2. Booking should be allowed only on weekdays.
3. Format of date should be dd-mm-yy. I was able to achieve all these functionalities individually but when I merge them either of them does not work. Here is the jQuery code for start date should be less than end date and end date should be more than start date.

<script>
    
$(document).ready(function () {
        $("#datepick").datepicker({
            onSelect: function (selected) {
                var dt = new Date(selected);
                dt.setDate(dt.getDate());
                $("#datepick1").datepicker("option", "minDate", dt);
            }
        });
        $("#datepick1").datepicker({
            onSelect: function (selected) {
                var dt = new Date(selected);
                dt.setDate(dt.getDate());
                $("#datepick").datepicker("option", "maxDate", dt);
            }
        });
    });
</script>

And this is the jQuery code for disabling weekends and changing the date format.

<script>
$(document).ready(function () {
    $("#datepick").datepicker({
        dateFormat: "dd-mm-yy",
        beforeShowDay: $.datepicker.noWeekends
    });
    
    $("#datepick1").datepicker({
        dateFormat: "dd-mm-yy",
        beforeShowDay: $.datepicker.noWeekends
    });
    
});
</script>

I tried combining these two but either one of the functionality does not work. Thank you in advance!!!
