Actually, Hera predates classical Greece and appears in Ancient Mycenaean and Minoan mythology as a supreme mother goddess. She reappears as the supreme female goddess of the Olympian rule and the one being that could lead to the destruction of the Olympian ruler Zeus just as previous mother goddess did to earlier rulers of the Titan (Rhea) and Primordial (Gaea) rule in Greek mythology.
Mythology does not give Hera - a Greek goddess - a age: for what is age in the face of immortality?
Demeter.
goddess
Aphrodite.
She was immortal. she didn't have an age.
You can give the hera pack once a mare is of age for breeding at two and a half years.
Hera isn't one age. She can make herself look any age she wants. But honestly REALLY OLD.There is no known date for Hera's birth so there is no way to know.
She was 15
Hera was a daughter of Cronus and Rhea (titans) which makes her a goddess by default.
I don't think she can die, since she is immortal, and she has lived for centuries, but she can become a person of any age at any time, so the answer is indefinite
Hephaestus was born of Hera.
