What's wrong with my code
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): delta = today - dt return delta.days >= 4745 def date_string(dt): return dt.strftime("%B %d") birth_dates = map(date_string, filter(is_over_13, birthdays))

It is looking more like an international date time round off with the sample data 9 Aug 2006 date being very close to exactly 13 years old.
Update: It is a bug in the checker that has a hard coded expected value. As the second date moved passed 13 years ago from today's date the results of the map/filter will change.
A temporary work-around would be to change the data so that the second date is at least 4 days later than date you run the challenge.:
birthdays = [ datetime.datetime(2012, 4, 29), # change line below to datetime.datetime(2006, 8, 13), # changed from (2006, 8, 9) datetime.datetime(1978, 5, 16), datetime.datetime(1981, 8, 15), datetime.datetime(2001, 7, 4), datetime.datetime(1999, 12, 30) ]
With this change, your code will pass the challenge!!

Hi Chris Freeman , just to confirm your suspicions, I do believe this was a bug in the checker. I had this problem las week too. Going back to this challenge, I tried your solution and unfortunately, it didn't work. I did however change other values in the birthdays list to random values and only then did I finally pass this challenge.
