Well... Aphrodite was never actually recorded as of a birth. But in circa 750 b.c. She was recorded to be "born" by her brother cronus making waves from the sea. There creating foam which then aphrodite arose on a giant shell covered in roses accompanied by a dolphin.
It's not actually known how Aphrodite was born. The most common myth is that she was born from the foam of the sea. Another myth is that when Kronos was killed and his blood dropped on the earth, Aphrodite sprung forth.
She was born at the time of the olympians
Its not really known. Some people say she was born way at the begining on time!!!!!
