not sure why it says got 55 expected 5. I ran the function locally and it works. if i did time1=datetime.datetime.now() and time2=datetime.datetime.now()+datetime.timedelta(minutes=+10)
and when i pass the values to my function minutes(time2,time1) it return 10 which is correct.
not sure why the code challenge shows 55.
import datetime
def minutes(time2,time1):
return round(time2.minute - time1.minute)

Treehouse Guest TeacherThe first datetime that comes to your function will always be older than the second one. Think of it like def minutes(older, newer):. Older datetimes should be considered "smaller" than newer ones (since dates get bigger as they go along). So you'll need to subtract the first one from the second one, newer - older, to get the right answer.

although it still says try again.
import datetime
def minutes(older,newer):
return round(newer.minute - older.minute)
this works fine locally when i pass values like older=datetime.datetime.now() and newer=now+datetime.timedelta(minutes=+5) which return 5 which is correct.

Treehouse Guest TeacherYou're assuming that the difference in their minutes is the same as the number of minutes between them. Consider 1:05pm and 1:00am. The difference in their minutes is 5 but the difference between them, in minutes, is (12*60)-5, which is a lot more than 5.
You need to subtract the older datetime from the newer one and then round() the minutes attribute of the timedelta that you get from that subtraction.
