#Q. 20:

#Seasoners(Control Stmt - if-elif-el)

#The year is divided into four seasons: spring, summer, fall and winter. While the exact dates that the seasons change vary a little bit from year to year because of the way that the calendar is constructed, we will use the following dates for this exercise:
#Season First day
#Summer March 20
#Spring  June 21
#Fall September 22
#Winter December 21                  
#Create a program that reads a month and day from the user. The user will enter the name of the month as a string, followed by the day within the month as an integer. 
#Then your program should display the season associated with the date that was entered. 
#Note: Enter First three letter for month example: Jan for january, Feb for Feburary ans so on....and first letter of the month should be capital
