Add multiple hidden fields in Django Form - django

Question

I'm using Django. I need a form that shows the 3 fields of a class that I have created, the idea is that every time you want to add a new day and time to start and end, show a new new section, so that each teacher can be found in more of a day and time of beginning and end (the three fields go together)
I still do not logo to make it work, if someone has any idea they would be grateful.
Models.py
class Profesor(Person):
legajo = models.IntegerField(blank=True, null=True)
type = models.CharField(max_length=30)
matter = models.CharField(max_length=100, blank=True, null=True)
calendar = models.ForeignKey('calendar', on_delete=models.DO_NOTHING)
user = models.CharField(max_length=20, blank=True, null=True)
class calendar(models.Model):
day = models.DateTimeField(default=date.today().isoweekday())
hs_init = models.DateTimeField(default=datetime.now().hour)
hs_end = models.DateTimeField(default=datetime.now().hour)
Forms.py
