Django: How to save checkbox choice?

I'm trying to save the user's choice of the checkbox for whether they have completed an event or not. I just want the checkbox to be able to save the user's previous choice on a page refresh. Every time the page refreshes the value is set back to False, or, unchecked.

utils.py

def formatday(self, day, events):
        events_per_day = events.filter(start_time__day=day)
        d = ''
        for event in events_per_day:

            d += f'<li><label> {event.get_html_url}  <input type="checkbox"></label></li>'

        if day != 0:
            return f"<td><span class='date'>{day}</span><ul> {d} </ul></td>"
        return '<td></td>'

views.py

def event(request, event_id=None):
    instance = Event()

    if event_id:
        instance = get_object_or_404(Event, pk=event_id)
    else:
        instance = Event()

    form = EventForm(request.POST or None, instance=instance)
    if request.POST and form.is_valid():
        event = Event.objects.create(**form.cleaned_data, user=request.user)
        print(event.title)
        return HttpResponseRedirect(reverse('cal:calendar'))
    return render(request, 'cal/event.html', {'form': form})

models.py

class Event(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=200)
    description = models.TextField(max_length=350)
    start_time = models.DateTimeField()
    end_time = models.DateTimeField()
    event_checked = models.BooleanField(default=False, blank=True)

    @property
    def get_html_url(self):
        url = reverse('cal:event_edit', args=(self.id,))
        return f'<a href="{url}">{self.title}</a>'

forms.py

class EventForm(forms.ModelForm):
  #event_done = forms.BooleanField()
  class Meta:
    model = Event

    # datetime-local is a HTML5 input type, format to make date time show on fields
    widgets = {
      'start_time': DateInput(attrs={'type': 'datetime-local'}, format='%Y-%m-%dT%H:%M'),
      'end_time': DateInput(attrs={'type': 'datetime-local'}, format='%Y-%m-%dT%H:%M'),
    }
    fields = ('title', 'description', 'start_time', 'end_time')

  def __init__(self, *args, **kwargs):
    super(EventForm, self).__init__(*args, **kwargs)
    # input_formats parses HTML5 datetime-local input to datetime field
    self.fields['start_time'].input_formats = ('%Y-%m-%dT%H:%M',)
    self.fields['end_time'].input_formats = ('%Y-%m-%dT%H:%M',)
