How do I integrate a calendar widget in my system? I wish to add the calendar widget to my form, which has been designed in Django. I’m attaching a screenshot showing where I want to integrate it. Also, I want the calendar widget to be like http://www.dynarch.com/projects/calendar/.
What file do I need to modify and what code do I need to use?

forms.py
or else there is also a another way using Javascript Using Django time/date widgets in custom form
