events (as a function)

A custom function for programmatically generating Event Objects.

function( start, end, timezone, callback ) { }

FullCalendar will call this function whenever it needs new event data. This is triggered when the user clicks prev/next or switches views.

This function will be given start and end parameters, which are Moments denoting the range the calendar needs events for.

timezone is a string/boolean describing the calendar’s current timezone. It is the exact value of the timezone option.

It will also be given callback, a function that must be called when the custom event function has generated its events. It is the event function’s responsibility to make sure callback is being called with an array of Event Objects.

Here is an example showing how to use an event function to fetch events from a hypothetical XML feed:

  events: function(start, end, timezone, callback) {
      url: 'myxmlfeed.php',
      dataType: 'xml',
      data: {
        // our hypothetical feed requires UNIX timestamps
        start: start.unix(),
        end: end.unix()
      success: function(doc) {
        var events = [];
        $(doc).find('event').each(function() {
            title: $(this).attr('title'),
            start: $(this).attr('start') // will be parsed

However, if you have the choice, JSON is a better idea because you can just specify a feed URL.

Extended Form

You can specify Event Source options. This often comes in handy when you are using the eventSources option to specify multiple event sources and you want certain options to only apply to certain sources. However, to do this, you must write things a little differently:


  eventSources: [

    // your event source
      events: function(start, end, timezone, callback) {
        // ...
      color: 'yellow',   // an option!
      textColor: 'black' // an option!

    // any other sources...
