Calendar Module Solution

weekday={0:'MONDAY',1:'TUESDAY',2:'WEDNESDAY',3:'THURSDAY',4:'FRIDAY',5:'SATURDAY',6:'SUNDAY'}
import calendar
m=[]
a=list(input().split())  #MM DD YYYY format
day=(calendar.weekday(int(a[2]),int(a[0]),int(a[1]))) #gives input in year,month,day format
print(weekday[day])

Explantion-

Calendar.weekday takes input in year,month,day format. So, we will give our input list a=[08,05,2015] in YYYY, MM, DD format to this function. In order to convert 08 to 8 and 05 to 5 we will typecast all values into int. 

calendar.weekday -returns the day of the week in integer values where 0 is MONDAY and soon..

To print the day name we will make the use of dictionary weekday which we created earlier in the code.
