title: Django calendar widget in a custom form
body: <p>I am trying to add a calendar date input to one of my forms. There is a wonderful calendar widget that Django uses on its admin pages, but I can't figure out how to add it to a custom form.</p>
  
  <p>I found a couple other questions about the same subject here, but they all seemed to be out of date, complicated, and not working.</p>
  
  <p>Is there a way to include Django's built in calendar widget into one of my forms?</p>
