[Answer]-Unable to retrieve data in django

You’re doing some odd things here: you’re converting to a time, then converting that to a datetime.date, then extracting the year, month and day as integers and passing them to the query. You could bypass almost the whole process: the only thing you need is to convert the month, the other parameters can be passed directly:

month_no = datetime.datetime.strptime(month, '%b').month
entry = get_object_or_404(Entry, pub_date__year=year, pub_date__month=month_no, pub_date__day=day, slug=slug)
