Frequently Asked Questions
What if I don't know my exact birth time?
If you don't know your exact birth time, use 12:00 PM (noon) as an estimate. Sun, Moon, and planet signs will still be accurate, though house placements and Rising sign may vary.
What makes a good compatibility score?
Scores above 65% indicate strong natural compatibility. However, lower scores don't mean a relationship is doomed - challenging aspects often create the passion and growth that make relationships meaningful.
Can this predict relationship success?
Astrology reveals tendencies and energies, not fate. High compatibility makes certain dynamics easier, but all relationships require effort. Use these insights as a tool for understanding, not a deterministic prediction.
