You can use the beforeShowDay option. I needed to disable any day past the 28th of the month. Here is my code.

$('.datepicker').datepicker({
    dateFormat: "yy-mm-dd",
    beforeShowDay: function(date) {
        var day = date.getDate();
        if (day > 28) {
            return [false];
        } else {
            return [true];
        }
    }
});

Here is more information about it: http://api.jqueryui.com/datepicker/#option-beforeShowDay

The date variable passed into the beforeShowDay callback is a JavaScript date object, so it can be formatted using various libraries, a timestamp can be retrieved using date.getTime(), etc.
