Multiple day events rarely have one start and one end time. For example, Birmingham Comic Con may last for 3 days, but you can't turn up at 1 in the morning! It has separate start and end times for each of the three days the event runs. I haven't been able to find anything in the docs about multiple start and end times per event, has anyone else?
Edit:
How I've got this working, in case anyone sees this and is after the same functionality, is by adding 'eventlength' and 'firstend', 'secondstart', 'secondend', 'thirdstart' as JSON values. This works for me as none of my events will be longer than three days. 'eventlength' is just a number (1, 2 or 3), and the rest are times/dates.
In fullCalendars eventClick section I have an if statement that cycles through the various possible event lengths and displays the appropriate values.
$startDf = 'ddd Do H:mma';
$endDf = 'H:mma';
if(calEvent.eventlength == 2){
$this.find('#event__info .event-date').text((calEvent.start).format($startDf) + ' - ' + moment(calEvent.firstend).format($endDf) + '\n' + moment(calEvent.seccondstart).format($startDf) + ' - ' + (calEvent.end).format($endDf));}
else if(calEvent.eventlength == 3){
$this.find('#event__info .event-date').text((calEvent.start).format($startDf) + ' - ' + moment(calEvent.firstend).format($endDf) + '\n' + moment(calEvent.seccondstart).format($startDf) + ' - ' + moment(calEvent.seccondend).format($endDf) + '\n' + moment(calEvent.thirdstart).format($startDf) + ' - ' + (calEvent.end).format($endDf));}
else {
$this.find('#event__info .event-date').text((calEvent.start).format($startDf) + ' - ' + (calEvent.end).format($endDf));}
this displays a three day event as one event on the calander, but outputs the following, which I think makes more sense than having 3 seperate one day events, or an event that is continuously open from 10am on day one to 4pm of day three.
