From the Roman calendar month Aprilis (April).

The Romans considered the month sacred to the goddess Venus, and its name may derive from that of her Greek equivalent, Aphrodite. It became the fourth month of the 12 "revised" month Roman Republican Calendar in 200 BC. Aphrodite is the Greek goddess of love and beauty. She is identified with the Roman goddess Venus. As part of the seasonal calendar April is the time of the 'Growing Moon'.
