Vertical Slider JS: Need To Add Extra Date


I’m having a hard time adding an extra date to this vertical slider that I found on this cloneable site which I’m customizing for the site I’m designing. I believe the answer probably has to do with configuring the js that is being used in tandem with the design, but I’m not experienced enough with js to figure it out.

I believe the answer may be within this function code…
