Answer 1

Assuming your datepicker has an id of datePicker: var pickedDate = $( "#datePicker" ).datepicker( "getDate" ); if ( pickedDate != null ) { pickedDate.setDate( pickedDate.getDate() - 5 ); } Then if you wanted to send that back to the datepicker: $( "#datePicker" ).datepicker( "setDate", pickedDate );
