Yeah, and the closest we've got to an actual birthday in terms of official material is the OMH claiming that she was 20 during the events of the Shadow Moses Incident (hinting at her being born either in 1983), and even that is contradicted a few sentences later, where they claimed she was five years old in 1988, hinting at her birthyear being 1983.
