A date is a date, and doesn't have a "format". A format applies when you represent the date as a string, or when you wish to interpret a string as a date.

You could play around with DATE_INPUT_FORMATS and similar settings for your project.

You define the setting in the settings.py file for your project. For instance:

DATE_INPUT_FORMATS = ('%d-%m-%Y', '%Y-%m-%d', '%m/%d/%Y', '%m/%d/%y', '%b %d %Y',
                      '%b %d, %Y', '%d %b %Y', '%d %b, %Y', '%B %d %Y',
                      '%B %d, %Y', '%d %B %Y', '%d %B, %Y')

You're better off worrying about the format on output, not how it is stored. A DateField is stored as your database's native column of the same type.

If you really want this, you can set DATE_FORMAT in your settings.py, like so:

DATE_FORMAT='d-m-Y'

This makes a default display like this:

Feb 5, 2010 

Look like this:

05-02-2010

Now of course there are other places where this will be overridden, such as the admin app and default form widgets, so it's not like this is a total solution to all your problems. Just get used to using datetime.datetime.strftime() like so:

>>> # using one of my own apps as an example where 'created' is a DateTimeField
>>> r.created
datetime.datetime(2010, 1, 28, 10, 5, 19, 38963)
>>> print r.created # default output (this is a Python default)
2010-01-28 10:05:19.038963
>>> print datetime.datetime.strftime(r.created, "%m-%d-%Y") # forcing it to m-d-Y format
01-28-2010
