django-copyright keeps your site's copyright notice up-to-date. Forever and ever.
Install copyright from the PyPI using:
pip install django-copyright
Add copyright to your INSTALLED_APPS
INSTALLED_APPS = (
'copyright',
)
set a COPY_START_YEAR in the django settings (this is an ingeter)
COPY_START_YEAR = 2009
to span a range.
Load copyrighttags in the template with {% load copyrighttags %}, afterwards place {% getCopyrightYears %} in the template, this will render a string like "2009 - 2012" or "2012" in case COPY_START_YEAR is not definied in your project settings.
