Well like I said, I instinctively consider the day I was born a birthday - just seems logical to me. But a lot of people don't citing only the celebration of that day annually is an actual birthday, and the day you are born is your birth date. This is splitting hairs at this point, so I went with the law. Legally, by US laws, birth date is defined as the day you are born, and birthday is defined as every anniversary of the birth date. These are distinguished to define ages at which you can legally participate in events, like driving, smoking, voting, joining the military, or drinking. On your 16th birthday, you can drive. If that included the day you were born, it would be what we all think of as our 15th birthday.
So I changed the wording to "not including the day he was born" just to take all the hair splitting and ambiguity out of the riddle.
