Skipping weekends and splitting days with an event block of 3 days using fullcalendar

I have a question relating to the plugin called "fullcalendar" that can be viewed here https://fullcalendar.io/docs/event-data

What I would like to achieve is a modification to my current script located below on my jsfiddle link. Which is to create a event split block when the external event is dragged and dropped near for example Friday, the event block of 3 days would split and would skip saturday and sunday and place the rest of the event block on Monday and Tuesday instead.

My script below currently places the external event of three days on any three days following the day you place the event.

To create the 3 days block I added the following

var threeDayBlock = new Date(date.getTime());
threeDayBlock.setDate(threeDayBlock.getDate() + 2);

copiedEventObject.end = threeDayBlock;
