Answer 2

No need to make parent and child relationship here is the code that provide simple solution for recurring events in jquery Full calender use these below functions in your php file that you use further to call all your events.

function render_fccalendar_events() {
        $_POST['start'] = strtotime('2013-05-01');
        $_POST['end'] = strtotime('2013-05-31');
        $start = date('Y-m-d',$_POST['start']);
        $end = date('Y-m-d', $_POST['end']);
        $readonly = (isset($_POST['readonly'])) ? true : false;    
        $events = fcdb_query_events($start, $end);       
        render_json(process_events($events, $start, $end, $readonly));
}

function process_events($events, $start, $end, $readonly) {
    if ($events) {
        $output = array();
        foreach ($events as $event) {
            $event->view_start = $start;
            $event->view_end = $end;
            $event = process_event($event, $readonly, true);
            if (is_array($event)) {
                foreach ($event as $repeat) {
                    array_push($output, $repeat);
                }
            } else {

}

in the above code i used repeat_desk in which i store json code for repeat frequency

and jquery to call your file

 events:  {
                url: '<?php echo $lgc_plugindir; ?>includes/imagerotator.php',
                data: {
                    action: 'get_events'
                },
                type: 'POST'
            }

i used this for wordpress you can use this code as per your requirement
