I have to do an errata corrige.
I said that NSLogs are printing the correct output, and it is true for 
all NSLog except for:

        NSLog(@"Numbers of Days %ld", monthDays);
        monthDays = 31;

That NSLog prints the value of monthDays that is "0" for some reason (It 
should be 31, now that is March). Please, also, ignore the line

        monthDays = 31

It was just for test and I forgot to delete it before sending the email.

Best regards,
Alex
