How to accept localized date format (e.g dd/mm/yy) in a DateField on an admin form?

Question

Is it possible to customize a django application to have accept localized date format (e.g dd/mm/yy) in a DateField on an admin form ?

I have a model class :

The fix proposed by Ben is working but the calendar on the right is not shown anymore.

Here is an improvement. The calendar will still be shown and the date will be displayed with the %d%%M/%Y format.

from django.forms.models import ModelForm
from django.contrib.admin.widgets import AdminDateWidget
from django.forms.fields import DateField  

class MyModelForm(ModelForm):
    date = DateField(input_formats=['%d/%m/%Y',],widget=AdminDateWidget(format='%d/%m/%Y'))
    class Meta:
        model = MyModel

class MyModelAdmin(admin.ModelAdmin):
    form = MyModelForm

When clicking on a day in the calendar, the value of the field has the %Y-%m-%d format but is is accepted as a valid date format.
