How to filter an object based on a datetime range in python (Django)

Question

I am trying to create a page with all the most recent posts.

class Post(models.Model):
     title = models.CharField(max_length=40)
     postTime = models.DateTimeField(auto_now_add=True)

I found this example:

 start_date = datetime.date(2005, 1, 1)
 end_date = datetime.date(2005, 3, 31)
 Post.objects.filter(postTime__range=(start_date, end_date))

I know I'm suppose to use the __range function. But how can I make it so that I can get all the posts from a range of today all the way to two weeks ago

something like this:

start_date = datetime.date(date from two weeks ago)
end_date = datetime.date(currentdate)
Post.objects.filter(postTime__range(start_date, end_date))

Answer 1

start_date = end_date - datetime.timedelta(days=14)

Answer 2

from datetime import date, timedelta

Post.objects.filter(postTime__range=(date.today(), date.today() - timedelta(days=14)))
