Answer 2

Can you try this:

change dataType to text

and eval the data.

natDays = eval('(' + data + ')');

Answer 3

I remember having trouble in similar cases in IE when I did not specify what response format I expected. Try setting dataType in the ajax request like so:

$.ajax({
    type: "GET",
    url: "include/getdate.php",
    data: dataString,
    dataType: 'json',
    success: successCallback
}

Also if you want to catch errors you should be able to specify an error callback like so:

$.ajax({
    ....
    error: errorCallback
    ....
}

function errorCallback(jqXHR, textStatus, errorThrown) {
    alert(jqXHR);
    alert(textStatus);
    alert(errorThrown);
}

That should help with debugging.
