Where do horoscopes predictions come from?

“Now astrologers do their calculations and forecasting based on where the planets and the sun are relative to the 12 signs —which are fixed — and not based on where they are relative to the constellations. Astrologers say if the sun is in the sign of Sagittarius on the day you were born, then you’re a Sagittarius.”

Who is the creator of horoscope?

Astrology originated in Babylon far back in antiquity, with the Babylonians developing their own form of horoscopes around 2,400 years ago.
