convert start_date
into python date object then do the filtering.
Example
from datetime import datetime
[1]:start_date = '2017-02-03'
[2]:start_date = datetime.strptime(startdate, '%Y-%m-%d')
[3]:start_date.year ## 2017
OutputData = Entity.objects.filter(created_on__year=start_date.year,
created_on__month=start_date.month,created_on__day=start_date.day).count()
