This very simple templatetag can take event objects from django-event-calendar and create the appropriate URLs to automatically allow users to add events from your website to Google calendar.

from django import template
from django.contrib.sites.models import Site
from django.utils.http import urlquote_plus

register = template.Library()

@register.filter
def google_calendarize(event):
    st = event.start
    en = event.end and event.end or event.start
    tfmt = '%Y%m%dT000000'

    dates = '%s%s%s' % (st.strftime(tfmt), '%2F', en.strftime(tfmt))
    name = urlquote_plus(event.name)

    s = ('http://www.google.com/calendar/event?action=TEMPLATE&' +
         'text=' + name + '&' +
         'dates=' + dates + '&' +
         'sprop=website:' + urlquote_plus(Site.objects.get_current().domain))

    if event.location:
        s = s + '&location=' + urlquote_plus(event.location)

    return s + '&trp=false'

google_calendarize.safe = True



And this code can be invoked via:
{% load project_events_tags %}
...
<a href="{{ event|google_calendarize }}">+ Add to Google Calendar</a>
