Queryset of people with a birthday in the next X days

Question

how do i get queryset of people with a birthday in the next X days? I saw this answer, but it does not suit me, because gets people only with current year of birth.

Answer 1

I can think of 2 ways without using custom queries, both with "problems"

1) Not efficient as it does 1 query per day

start = datetime.date.today()
max_days = 14
days = [ start + datetime.timedelta(days=i) for i in xrange(0, max_days) ]

birthdays = []
for d in days:
    for p in Profile.objects.filter(birthday__month=d.month, birthday__day=d.day):
        birthdays.append(p)

print birthdays

2) Single query, but requires a model change. You would need to add bday_month and bday_day integer fields. These can obviously be populated automatically from the real date.

The limitation of this example is that you can only check against 2 months, start month and the end month. Setting 29 days you could jump over february, showing only Jan 31 and Mar 1.

from django.db.models import Q    
start = datetime.date.today()
end = start + datetime.timedelta(days=14)

print Profile.objects.filter(
    Q(bday_month=start.month) & Q(bday_day__gte=start.day) | 
    Q(bday_month=end.month) & Q(bday_day__lte=end.day)
)
