English to ancient greek translation

[Skullheadhq]

Y'know, the Greeks didn't used Christian years.
Since your son is born in march he was born in the 3rd year of the 693th Olympiad.
Austin is not an Greek name, it would be Αυστιν or Oιστιν transscribed, a good hellenized name for Austin would be Αυγουστίνος (Augoustinos).
March is another story:

Elaphebolion February/March

Mounichion March/April

Since your son is born the 30th I think he was born in the ancient Greek month of Mounichion.
