Historcially, there have been several cases where someone THOUGHT they were born on Monty/Day/Year only to find, once their birth certificate was recovered, or, for some older folks the family Bible. That their date of birth was OTHER than what they thought.
And there are many cases of a baby in a basket, left on the church steps or the orphanage or the hospital. The doctors take their best guess as to the age of the child. Well, thanks to modern science he finds out he's a "Montpiellier" or perhaps a "Jones" and manages to track down his actual birth record..... THus finding out his real DOB.
So it can happen. Rare in the larger picture, but it can happen.
