I have a model and a signal in models.py and this model sends message to discord webhook with how many days left to something. I want to refresh it everyday at **12:00** AM everyday automatically without using django-celery cause it doesnt work for me. My plan is do something like this

```py
time_set = 12

if time_set == timezone.now().hour:
   ...save model instances...

```

but i have totally no idea how to do it
And i want to do it this way cause when model instance are saved signal runs
