Filtering by custom date range in Django admin

In django 1.4, you can user list_filter. try:

from django.contrib.admin import DateFieldListFilter
class PersonAdmin(ModelAdmin):
    list_filter = (
        ('date_field_name', DateFieldListFilter),
    )

This will give some built-in ranges, but it will work if you put the date range in url, like:

?date__gte=2009-5-1&date__lt=2009-8-1

If you need a date picker (like jquery), then you need to extend DateFieldListFilter. I sent a patch to django-admin-filtrate, so, check there soon.
