A possible match compares Hebrew day and actual month, without the year. Adar, Adar I and Adar II stay distinct; this is not a ruling on when to observe a birthday.
36 curated lives from Wikidata and linked biographies. Their birth times are unknown, so both Hebrew dates remain possible. Calendar connections invite learning; they do not explain someone’s achievements, beliefs or personality.
