Frequently Asked Questions
Why is an accurate birth time required for the Rising sign?
The Earth rotates 360 degrees every 24 hours, meaning the Rising sign (Ascendant) changes approximately every two hours. An accurate birth time to the nearest minute ensures an exact Ascendant calculation.
What are the "Big Three" in astrology?
The Big Three consist of your Sun sign (core identity and vitality), Moon sign (inner emotional world and instincts), and Rising sign (how you navigate the world and first impressions).
