You need something called cron or cronjob. Very easy to use is django-crontab.

Install:

$ pip install django-crontab

your_app/cron.py:

def my_scheduled_job():
  # check every Vehicle's insurance if is exactly 5 days from expiring

settings.py:

INSTALLED_APPS = (
    'django_crontab',
    ...
)

# it will execute this function at 4:59 every single day
CRONJOBS = [
    ('59 4 * * *', 'your_app.cron.my_scheduled_job')
]

Then activate / control / remove with commands:

$ python manage.py crontab add
$ python manage.py crontab show
$ python manage.py crontab remove
