How do I get the 'Calendar' app to display on the Dashboard? [MacOS C-Error]

As per the title.  I've tried using ctrl up-arrow and dragging onto that 'desktop' but my drag is rejected...

I want to be able to see my appointments at a glance in the Dashboard, not just a static calendar with a clock.

While looking for answers to this question, I came across something called DashCode, which I understand does not exist for MacOS Sierra.  Can this be used to wrap the calendar app into a widget?
Use this widget, hope it can help you :)
