Use sorted() and attrgetter() to sort date_list by the day attribute of each datetime object. Save this sorting into a variable named sorted_dates
import datetime from operator import attrgetter date_list = [ datetime.datetime(2015, 4, 29, 10, 15, 39), datetime.datetime(2006, 8, 15, 14, 59, 2), datetime.datetime(1981, 5, 16, 2, 10, 42), datetime.datetime(2012, 8, 9, 14, 59, 2), ] sorted_dates = sorted(datetime.datetime, key=attrgetter('day'))

You have the right idea, but the first argument to "sorted" must be the thing that you are going to sort, which in this case is the "date_list":
sorted_dates = sorted(date_list, key=attrgetter('day'))
