Frequently Asked Questions

Is zodiac compatibility accurate for relationships?

Astrological compatibility provides valuable insights into relationship dynamics, but it's not deterministic. Our AI analyzes how your charts interact, revealing natural strengths and potential challenges. While astrology can't predict relationship success, it offers guidance for understanding each other better and navigating differences. Use it as a tool for self-awareness and relationship growth.

Do I need both people's birth times?

For the most accurate compatibility analysis, yes. Birth times are essential for calculating rising signs, Moon signs, and house positions - crucial factors in relationship compatibility. However, if you only have birth dates, we can still provide sun sign compatibility analysis, though it will be less comprehensive and personalized.

What is a good compatibility score?

Compatibility scores typically range from 40-90%. Above 70% indicates strong natural compatibility with many harmonious aspects. 60-70% shows good potential with some areas needing compromise. Below 60% suggests more challenges, though successful relationships are still possible with awareness and effort. Remember, low compatibility doesn't mean incompatibility - it means you'll need more conscious work.

Can incompatible signs have successful relationships?

Absolutely! So-called 'incompatible' signs can have fulfilling relationships. Astrological compatibility shows natural dynamics, not destiny. Challenging aspects can create growth opportunities and passion. What matters most is awareness, communication, and willingness to understand each other. Use compatibility insights to navigate differences, not to determine relationship viability.

What makes two zodiac signs compatible?

True compatibility goes beyond sun signs. Key factors include: harmonious aspects between Venus and Mars (attraction), Moon compatibility (emotional understanding), complementary elements (fire/air or earth/water), supportive house overlays, and balanced composite chart. Our AI analyzes all these factors plus hundreds more to give you comprehensive compatibility insights.
