Your initial data list only has (num_events - 1) elements. And
formset_factory is returning a formset class that generates 1 extra
form by default, giving you num_events total forms.
If you don't want any extra forms, you can pass extra=0 into
formset_factory like so:
DateTimeFormSet = formset_factory(DateTimeForm, extra=0)
