Populating Django ManyToManyField with custom data from another django model

I have the Model1 of app1

class Event(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField(max_length=500)
    eventdate = models.DateField()
    created = models.DateTimeField(auto_now_add=True)

Model 1 of app2

class Register(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    select_the_event = models.ManyToManyField(Event)
    created = models.DateTimeField(auto_now_add=True)

Event database contain event information for one complete year.

How to populate the "select_the_event" with list of selected events that are valid for next 60 days?

If you are have forms.py for the Register model, then inside the RegisterForm class you can add attribute

class RegisterForm(forms.ModelForm):
    ....
    ....
    select_the_event = forms.ModelMultipleChoiceField(queryset=Event.objects.filter(
        event_date__range=[datetime.datetime.now().date(), datetime.datetime.now().date() + datetime.timedelta(60)])
)

In your ModelForm, assign a custom queryset to the ModelMultipleChoiceField for select_the_event:

select_the_event = forms.ModelMultipleChoiceField(
                     queryset=Event.objects.filter(...))
