Just a mind gap here. Can someone please help me figure this out?

I'm having an issue remembering how to run the method in this function for the month day

birthdays.py 
import datetime

birthdays = [
    datetime.datetime(2012, 4, 29),
    datetime.datetime(2006, 8, 9),
    datetime.datetime(1978, 5, 16),
    datetime.datetime(1981, 8, 15),
    datetime.datetime(2001, 7, 4),
    datetime.datetime(1999, 12, 30)
]

today = datetime.datetime.today()

def is_over_13(dt):
    # compare total days
    delta = today - dt
    return delta.days >= 4745

def date_string(dt):
    return strftime.datetime(%B %d)

For the last task, you have to use map() and filter() which each take a function and an iterable to apply the function to. For map() and filter() the function argument is just the name of the function you want to apply.

birth_dates = list(map(date_string, filter(is_over_13, birthdays))) OR birth_dates_com = [date_string(j) for j in [i for i in birthdays if is_over_13(i)]]
