Can Datepicker get dateMin from span?

Can Datepicker get dateMin from span?

I have this span:
  1. <div id="Availability" style="display: hidden">8</div>

Then I have a giant chunk of script for the jQuery ui datepicker:
  1.   //datepicker
        var natDays = [
            [1, 1, 'New Year'], //2014
            [1, 20, 'Martin Luther King'], //2014
            [2, 17, 'Washingtons Birthday'], //2014       
            [5, 26, 'Memorial Day'], //2014
            [7, 4, 'Independence Day'], //2014
            [9, 1, 'Labour Day'], //2014
            [10, 13, 'Columbus Day'], //2014
            [11, 11, 'Veterans Day'], //2014
            [11, 27, 'Thanksgiving Day'], //2014 
            [12, 25, 'Christmas'] //2014     
            ];

        // dateMin is the minimum delivery date
        var dateMin = new Date();
        dateMin.setDate(dateMin.getDate() + (dateMin.getHours() >= 13 ? 1 : 0));

        function AddBusinessDays(curdate, weekDaysToAdd) {
            var offset = (weekDaysToAdd > 0 ? +1 : -1);
            weekDaysToAdd = Math.abs(weekDaysToAdd);
            var date = new Date(curdate.getTime());
            while (weekDaysToAdd > 0) {
                date.setDate(date.getDate() + offset);
                //check if current day is business day
                if (noWeekendsOrHolidays(date)[0]) {
                    weekDaysToAdd--;
                }
            }
            return date;
        }

        function noWeekendsOrHolidays(date) {
            var noWeekend = $.datepicker.noWeekends(date);
            return (noWeekend[0] ? nationalDays(date) : noWeekend);
        }

        function nationalDays(date) {
            for (i = 0; i < natDays.length; i++) {
                if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) {
                    return [false, natDays[i][2] + '_day'];
                }
            }
            return [true, ''];
        }

        function setDeliveryDate(date) {
            $('#datepicker3').text($.datepicker.formatDate('DD, MM d, yy', AddBusinessDays(date, -2)));
            $('#datepicker2').text($.datepicker.formatDate('DD, MM d, yy', AddBusinessDays(date, -3)));
            $('#local-delivery-date').text($.datepicker.formatDate('DD, MM d, yy', AddBusinessDays(date, -3)));
        }

        $('#delivery-date').text($.datepicker.formatDate('DD, MM d, yy', AddBusinessDays(dateMin, 5)));
        setDeliveryDate(AddBusinessDays(dateMin, 5));


        $.datepicker.setDefaults({
            beforeShowDay: noWeekendsOrHolidays,
            showOn: 'both',
            firstDay: 0,
            dateFormat: 'mm/dd/yy',
            changeFirstDay: false,
            showButtonPanel: true
        });
        // use datepicker to choose a different delivery date    
        $('#datepicker').datepicker({
            minDate: AddBusinessDays(dateMin, 5),
            onSelect: function(datestring) {
                setDeliveryDate($(this).datepicker('getDate'));
            }
        });
        $('#LocalDate').datepicker({
            minDate: AddBusinessDays(dateMin, 2)
        });  









































































Wondering if it's possible to get the number within my span, in this case 8, and have the datepicker use that as the minDate here (rather than the 5):
  1. $('#datepicker').datepicker({
            minDate: AddBusinessDays(dateMin, 5),
Thanks very much in advance, all help is appreciated!
