Highlight start of week Javascript/JQuery UI datepicker

I have the datepicker working and it is fully functional.

The TD that is selected has the class ui-datepicker-current-day, so that might be what you want to find. You can do the highlighting by attaching a click event with the datepicker element, e.g.

$( "#datepicker" ).datepicker().click(function(event) {

    $(".ui-datepicker-current-day").parent().addClass('highlight');

    // highlight the TD > A
    $(".ui-datepicker-current-day").siblings().find('a').addClass('highlight2');
}); 

And you can define the highlight and highlight2 classes to your heart's content.

$(".ui-datepicker-today").parent().addClass(...)
