filter Datetimefield

Hi,  i'm new in django and python,

I'm trying to create a queryset to filter according to date.

this is my MODEL :  data = models.DateTimeField()

and my VIEW:        def resultado(request, dia, mes, ano):

                           lista_de_balada= Balada.objects.filter(data__year=ano, data__month=mes, data__day=dia)

                           context = {'lista_de_balada':lista_de_balada}

                           return render(request, 'procurar.htm', context)

it presents no errors, but the query is aways empty...    if i take off   __month     and    __day  it works fine.   but i need to filter according to date  not only year.

Sorry for the english, is not my native language.
