Frequently Asked Questions
What is the Big Three in astrology?
The Big Three refers to your Sun sign (outer ego and identity), Moon sign (inner emotional soul), and Rising sign or Ascendant (how you interact with the outside world).
Why is birth time so critical for the Rising sign?
The Rising sign changes approximately every two hours as the Earth rotates 360 degrees in 24 hours, so an accurate birth time is vital.
