add second date (might have been posted twice)

I need to add two date pickers with different dates blocked out. Does any one have any ideas how this can be done using dynamic fill option?

thank you. populating the date is not necessary, but setting dates off is another issue. the sample is crude, but works for demo. i'll use ajax function in word press to get data or create my own if necessary. to populate the array with needed values.

jQuery(document).ready(gformInitDatepicker);
var unavailableDates = ["28-7-2012","29-7-2012","30-7-2012"];

function gformInitDatepicker(){
    jQuery('.datepicker').each(
        function (){
            var element = jQuery(this);
            var format = "mm/dd/yy";
            var mDays = 2;
            var image = "";
            var showOn = "focus";
            if(element.hasClass("datepicker_with_icon")){
                showOn = "both";
                image = jQuery('#gforms_calendar_icon_' + this.id).val();
            }
            var opts = ttgSetDateOptions(element);
            opts.beforeShowDay = unavailable;
            element.datepicker(opts );
        }

    );
}

function unavailable(date) {
    dmy = date.getDate() + "-" + (date.getMonth()+1) + "-" + date.getFullYear();
    if (jQuery.inArray(dmy, unavailableDates) < 0) {
        return [true,"","out"];
    } else {
        return [false,"","in"];
    }
}

function ttgSetDateOptions(date) {
    var image = "";
    var showOn = "focus";
    var thsoptions =  {
        duration: "slow",
        hideIfNoPrevNext: true,
        yearRange: '-0:+0',
        minDate: +2,
        maxDate: 30,
        gotoCurrent: false,
        defaultDate: +2,
        showOn: showOn,
        buttonImage: image,
        buttonImageOnly: false,
        dateFormat: "mm/dd/yy"
    }

    return thsoptions;
}
