The day is the number a user will input to get the result that is older than (days from user input). For example, if user inputs 32 days, they will get the results that are older than 30 days.

A quick try-out:

class Entry(models.Model):
    entered = models.DateTimeField()

>>> from datetime import datetime
>>> Entry(entered = datetime.now()).save()
>>> Entry.objects.filter(entered__lte = datetime.now())
[<Entry: Entry object>]
>>> Entry.objects.filter(entered__gte = datetime.now())
[]
>>> Entry.objects.filter(entered__gte = datetime.now(), entered__lte=datetime(2009,11,1,0,0))
[<Entry: Entry object>]

My problem and my trying 

xxxx__day__lte.

last_contact_filled input from input field

for day_filter in xrange(1,int(last_contact_filled)+1):
                qdict['last_contact__day']=day_filter

What's the best way to do this in Django to filter by day(s) in my case?

Something like this would work for you:

from datetime import datetime, timedelta
how_many_days = 30
MyObject.objects.filter(entered__lte=datetime.now()-timedelta(days=how_many_days))
user_2236320

Add a timedelta(-30) to the datetime in the filter.
