Is there any functions/methods/options in fullcalendar that handles my recu

Simple Repeating Events

To add a simple alternative to those listed here, Fullcalendar now (somewhat) supports weekly recurring events. So if you only need something like: [Every Monday and Thursday from 10:00am to 02:00pm], you can use the following:

events: [{
    title:"My repeating event",
    start: '10:00', // a start time (10am in this example)
    end: '14:00', // an end time (2pm in this example)
    dow: [ 1, 4 ] // Repeat monday and thursday
}],

This is documented in Background events but it works for regular events as well.

Saving this to a database wouldn't be hard.

Add some restrictions

If you don't want them to repeat infinitely, you would need to add some start and end dates.

So, in the DB:

• Let the event shown above represent the parent record
• Have another table with start/end dates.
• Joined table example:

eventId  timeStart  timeEnd   dow    dateStart      dateEnd
     1      10:00    12:00  [1,4]  2015/03/01   2015/04/01  // Month of March
     1      10:00    12:00  [1,4]  2015/05/01   2015/06/01  // Month of May
     1      10:00    12:00  [1,4]  2016/01/01   2017/01/01  // Year of 2017

Pass this to the client as JSON:

{ id:1, start:"10:00", end:"12:00", dow:[1,4],
  ranges[{start:"2015/03/01", end:"2015/04/01"},
         {start:"2015/05/01", end:"2015/06/01"},
         {start:"2016/01/01", end:"2017/01/01"},]
}

And client side, use fullcalendar's eventRender to only render events when there are within one of the time ranges. Something like this should work:

eventRender: function(event){
    return (event.ranges.filter(function(range){ // test event against all the ranges

        return (event.start.isBefore(range.end) &&
                event.end.isAfter(range.start));

    }).length)>0; //if it isn't in one of the ranges, don't render it (by returning false)
},

That's assuming your events are structured as:

var repeatingEvents = [{
    title:"My repeating event",
    id: 1,
    start: '10:00', 
    end: '14:00', 
    dow: [ 1, 4 ], 
    ranges: [{ //repeating events are only displayed if they are within at least one of the following ranges.
        start: moment().startOf('week'), //next two weeks
        end: moment().endOf('week').add(7,'d'),
    },{
        start: moment('2015-02-01','YYYY-MM-DD'), //all of february
        end: moment('2015-02-01','YYYY-MM-DD').endOf('month'),
    },/*...other ranges*/],
},/*...other repeating events*/];

Overnight

In case you want overnight repeating events (like here), just go over 24:00 for the end time. For instance:

{
  start: '10:00', //starts at 10 on monday
  end:   '27:00', //24+3 is handled correctly.
  dow: [1]
}
