adjusting period of time for upcoming birthdays with django-birthday

Hi there,

I#m trying to adjust the period of Time for upcoming birthdays according to the documentation of “django-birthday” from today to tomorrow, but i am new to Django and Python, maybe i make a syntax-failure?

My code:
Hi, want to change the period for upcoming BDays being counted from tomorrow, not today. i am new to python and django, so i am sure it is my fault and i forgot something in the syntax:

def my_view(request)

return render (request, bday.html {
'upcoming_birthdays': Employees.objects.get_upcoming_birthdays(after=1)

delivers a “‘str’ object has no attribute ‘timetuple’” error in runtime…

if i leave () blank in the end of the code, everything works fine aside the fact that today is also counted for upcoming birthdays…

django-birthday doc:

Thx in advance for any tips

Hey there!
It will be helpful to include the template you’re rendering, and the traceback that’s displayed on the console.

can send yout the tracxeback as pdf by PN

The traceback can be posted here, the same as you do with code.

It’s hard to be precise without it, but i think that this is incorrect, you have a upcoming_birthdays key defined on the context.

But you’re iterating over a birthdays key.

no, that’s correct (and working)…should have posted the view also i think:

def birthday(request):

    context= {
        'today_birthdays': Employees.objects.get_birthdays(),
        'upcoming_birthdays': Employees.objects.get_upcoming_birthdays(days=8),
        'birthdays': Employees.objects.order_by_birthday()

    return render(request, 'birthday.html', context)

The problem ist to tell the “.get_upcoming_birthdays(days=8),” when to start counting, see also linked documentation in my first post. Restriction to 8 days as an argument works, but trying the “after=1” argument results in “missing timetuple” error.

I see.
I’ve read the documentation, and it says something really interesting

Warning : This library is pretty hacky. Use it if you’re lazy, not if you’re concerned about your code quality!

I think you may be better implementing this on your own, the library seems to be without any work from 2 years from now.

yeah, i was somehow afraid of this kind of judgement, i also sended an email zto the owner of the github repository with no answer yet…too bad.
There are also some faults in dealing with birthdays in leap years…so i think i will have to do it myself in the end but thanks for your thoughts :slight_smile:

So in case, somebody should have similar problems: THIS Solution is working for my purposes:

def birthday(request):
    # For TODAY Birthdays
    datetime_now =
    now_day, now_month =, datetime_now.month

    # For Birthdays within the next 7 days
    def day_tuple(day_offset):
        today =
        date = today + timedelta(day_offset)
        return (, date.month)

    one_week = timedelta(weeks=1)
    seven_days = [day_tuple(day) for day in range(one_week.days)]

    upcoming_birthdays = []
    for day, month in seven_days:
        upcoming_birthdays += Employees.objects.filter(

    context= {
        'today_birthdays': Employees.objects.filter(birthday__day=now_day, birthday__month=now_month),
        'upcoming_birthdays': upcoming_birthdays,
        'all_birthdays': Employees.objects.exclude(birthday__isnull=True)
    return render(request, 'birthday.html', context)
