With the majority of saints, particularly very ancient saints, there is no record of the birth dates. The only date that is recorded is the feast day of the saint which may be the anniversary of the death of the person when the person was reborn into heaven. Therefore, this question can not be answered.

Saint Olivia is eligible for Catholic Confirmation. However some people say that she is fiction. I have done my research on Saint Olivia and have concluded that Saint Olivia is in fact fiction. But she is still eligible for Catholic Confirmation. Even though she is fiction she is still a Saint that people have believed in and cherished for century's. Many Catholic people still believe she is real. So technically if you want to have your Catholic Confirmation name as: Saint Olivia go right ahead!If you have recently figure out that Saint Olivia is fiction and you are nervous about if your Catholic Confirmation name will work it will!Roman Catholic AnswerBlessed Olivia's feast day is June 10, she is not a saint, she has only been beatified (the last step before being declared a saint). If you are permitted beati names, then, yes, she would be eligible.
