if(mm==1 or mm==3 or mm==5 or mm==7 or mm==8 or mm==10 or mm==12):
elif(mm==4 or mm==6 or mm==9 or mm==11):
elif(yy%4==0 and yy%100!=0 or yy%400==0):
if(mm<1 or mm>12):
    print("Date is invalid.")
elif(dd<1 or dd>max1):
    print("Date is invalid.")
elif(dd==max1 and mm!=12):
    print("The incremented date is: ",dd,mm,yy)
elif(dd==31 and mm==12):
    print("The incremented date is: ",dd,mm,yy)
    print("The incremented date is: ",dd,mm,yy)


Enter the date in dd/mm/yy format:  25/04/2020
