What is the word for being born and dying on the same day?

Abortion.

Not true in every case, although there are many abortions. There are also such things as stillbirths where the baby just never begins to breathe & live in the world outside of the womb. Additionally, there are also babies who live an hour or a few hours in the pediatric ICU & expire, therefore having being born & died on the same day of the SAME YEAR.

I believe the person asking the question was really meaning the term which describes a person who lived a life & died on the same date on which they were born BUT in a different year.
