I have a form with following Javascript.
I want to ALLOW specific dates, although these dates could be disabled following this code.
Can I get some script to override and enable a specific Monday (for orders for Christmas, Newyear) for example?

<script type="text/javascript">
jQuery(document).ready(function(){
myDateTPicker = RSFormPro.jQueryCalendar.calendars[3];
myDateTPicker.callbackSelectedDateTime = function(selectedDateObject, calendarInstance, calendarDateObject, input, inputFormat) {
weekDay = calendarDateObject.getDay();
if(weekDay == 0 || weekDay == 1 || weekDay == 2 || weekDay == 5 || weekDay == 6){
//0 = Sunday, 1 = Monday and so on...
alert('Gelieve een woensdag of donderdag, vanaf volgende week, te selecteren.');
return false;
}
}
});
</script>


//Start of the week (day)
<script type="text/javascript">
jQuery(document).ready(function(){
myDateTPicker = RSFormPro.jQueryCalendar.calendars[3];
myDateTPicker.calendarInstance.setOptions({
dayOfWeekStart: 1
//0 = Sunday, 1 = Monday and so on...
});
});
</script>

//disable weekdays other than Thursday, Wednesday
<script>
jQuery(function() {
RSFormPro.jQueryCalendar.calendars[03].calendar.datetimepicker({disabledWeekDays:[0,1,2,5,6]});
});
</script>

//disable special dates (mm/dd/yyyy)
<script type="text/javascript">
jQuery(document).ready(function(){
var myDisabledDates = ;
//the dates you want to disable
myDateTPicker = RSFormPro.jQueryCalendar.calendars[03];
//replace 25 with your form ID and the date time picker name.
myDateTPicker.calendarInstance.setOptions({
disabledDates: myDisabledDates
});
});
</script>
