[Django]-How to subtract two django dates in template

I would make a method on the Employee object.

class Employee(models.Model):
    ...
    def ends_within_50_days(self):
        return (date.today() - self.end_date).days <= 50

Now you can just do:

{% if instance.ends_within_50_days %}

As suggested in the previous answer, you could make a method, or I’d go with property, in your model class.

Assuming that you have something like this:

from datetime import date
from django.db import models

class Employee(models.Model):
    end_date = models.DateField()
    # ... rest ...

    @property
    def age_in_days(self):
        today = date.today()
        result = self.end_date - today
        return result.days

In your template you can check if it is less than 50 days old:

{% if instance.age_in_days <= 50 %}

The property age_in_days will return the difference in days between today and the value of end_date as an integer. This should give you more flexibility in case you want to check not only if it is less than 50 days old. Eventually that requirement might change. Then you could reuse the property without refactoring your models.

You can still define a method in your model class to check if the instance ended within the last 50 days:

def ended_in_the_last_50_days(self):
    return self.age_in_days <= 50
