Based on the discussion at Empty Thoughts (http://blog.michaeltrier.com/2007/8/6/age-in-years-calculation) I built a quick and dirty custom filter.

Save this as a file in your "templatetags" folder. I called mine "calculate_age.py" and then in your template "{% load calculate_age %}" then use it, "{{ object.birthdate|age }}"

from django import template
import datetime

register = template.Library()

def age(bday, d=None):
    if d is None:
        d = datetime.date.today()
    return (d.year - bday.year) - int((d.month, d.day) < (bday.month, bday.day))

register.filter('age', age)
