To disable weekends (Saturdays and Sundays) in jQuery UI Datepicker, you can use the beforeShowDay option to specify the selectable dates. Here's the precise solution:
$(function() {
$("#datepicker").datepicker({
beforeShowDay: function(date) {
// day 0 = Sunday, day 6 = Saturday
return [date.getDay() !== 0 && date.getDay() !== 6, ''];
}
});
});
