Answer
Aglae Drogli, Eminescu's elder sister, played a crucial role in verifying and confirming the poet's actual date of birth. Eminescu's birth date had been misrecorded as December 15, 1849, but it was Aglae's meticulous examination of family documents, particularly a baptismal certificate, that definitively established his true birth date as January 15, 1850. Her contribution clarified a long-standing historical discrepancy and ensures that we commemorate Eminescu's legacy accurately.
