We are going to see how to exclude recurrent date from jquery ui datepicker. below example code shows, how to exclude every month 28 date from calender.

var excludedays = { "recurrent_date": [28]};

$('#caleder').datepicker({
   beforeShowDay: function(date){
       if(recurrent_date(date)){
           return [false];
       }
       return [true];
   }
});

function recurrent_date(date){
   return ($.inArray(date.getDate(),excludedays.recurrent_date) > -1);
}

jQuery datepicker exclude period.

Here i have explained how to exclude specific period of time from jquery ui calendar. below example excludes specified from date to specified to date. So it disable the given period of date from datepicker.

var excludedays = { "period": [{ "from": "2/21/2012", "to": "2/22/2012" }]};

   beforeShowDay: function(date){
       if(period(date)){
           return [false];
       }
       return [true];
   }
});

function period(date){
   var i, num, period, start, startArray, end, endArray;
   num = excludedays.period.length;
   for(i=0;i<num;i++){
       period = excludedays.period[i];
       startArray = period.from.split('/');
       start = new Date(startArray[2], (startArray[0] - 1), startArray[1]);
       endArray = period.to.split('/');
       end = new Date(endArray[2], (endArray[0] - 1), endArray[1]);        
       if(date>=start && date<=end){
           return true;
       }
   }
   return false;
}

jQuery datepicker exclude recurrent period.

In some case, We need to do some custom work on this calendar. So we are going to do one simple function to exclude the recurrent period of dates in jQuery datepicker. Using this function recurrent period of dates will be disabled from calender, Those recurrent period of dates will not available to user.

var excludedays = { "recurrent_period": [{ "from": "2/28/2012", "to": "2/29/2012","period": "monthly" },{ "from": "2/7/2012", "to": "2/9/2012","period": "yearly" }
 ]};
$('#caleder').datepicker({
 beforeShowDay: function(date){
 if(recurrent_period(date)){
 return [false];
 }
 return [true];
 }
 });
function recurrent_period(date){
 var i, num, period, recurrence, startArray, endArray, startDay, endDay, start, end;
 num = excludedays.recurrent_period.length;
 for(i=0;i= startDay && date.getDate() =start && date<=end){
 return true;
 }
 }
 }
 return false;
 }

Hope it helps.
