eventSources
A way to specify multiple event sources.
Array
This option is used instead of the events option.
You can put any number of event arrays, functions, JSON feed URLs, or full-out Event Source Objects into the eventSources array.
Here is an example calendar that displays two JSON feeds:
var calendar = new Calendar(calendarEl, {
eventSources: [
'/feed1.php',
'/feed2.php'
]
});
