I would make calculateAge a method on the Person model - or even
better, make a method that's a shortcut to it:
class Person(models.Model):
...
def get_age(self):
return calculateAge(self.date_of_birth)
Then in the template you could just do:
{% for person in borntoday %}
<li><a href="{{ person.get_absolute_url }}">{{ person }}
({{ person.get_age }})</a></li>
{% endfor %}
or whatever you want.
On your question as to whether this is the right approach, there's
nothing definitely wrong with it but I would say this belongs better
in a template tag. In fact you could make the whole template snippet
above into an inclusion tag, then simply insert it in any of your
templates with a single tag.
