You might want to use relativedelta from dateutil, it's more convenient to calculate the time:

import datetime
from dateutil.relativedelta import relativedelta

today = datetime.date.today()
age_25 = (today - relativedelta(years=25)).year
age_36 = (today - relativedelta(years=36)).year
Employees.objects.filter(birth_year__lte=age_25, birth_year__gte=36)

age_25 is 25 years ago, age_36 is 36 years ago, you just query the people's birthdays fall between 25 and 36 years ago.

For lte and gte check django doc for details.

Edit:

Actually, django orm supports range query, so just do:

Employees.objects.filter(birth_year__range=[age_36, age_25])
