FullCalendar inserts 1.5 hours on renderEvent

When I call my FullCalendar 开发者_JS百科like so:

   dayCalendar.fullCalendar('renderEvent',
     {
    title: "Scheduled Callback",
    start: callbackDate,                            
    allDay: false
     },
     true // make the event "stick"
   );

it sticks in an event with a duration of 1.5 hours even though I haven't set an end date/time. How do I ensure it sets an event with no duration or an event for just 30 minutes. My calendar is set to show events in blocks of 30 mins.

You are looking for the defaultEventMinutes option in your setup for full calendar just set this option to 30.

I hope this helps!
