Frequently Asked Questions
How is this different from basic sun sign compatibility?▼
Sun sign compatibility only looks at one planet. Our calculator analyzes Venus, Mars, and Moon placements to reveal how you love, desire, and emotionally connect — giving you a much more complete and accurate picture.
Why does birth time matter?▼
Birth time determines your Moon sign, which changes every 2-3 days. Without it, we estimate your Moon position, but adding your exact birth time gives you a much more precise emotional compatibility score.
How accurate is the compatibility score?▼
Our scores are based on real astrological aspects between your planetary placements. While no calculator can capture every nuance of a relationship, it provides genuine insights rooted in astrological tradition.
What do the different dimensions mean?▼
Each dimension measures a different layer of compatibility: Sun reflects core identity, Venus shows love style, Mars reveals passion and chemistry, and Moon captures emotional bonding and intimacy.
Can I use this for non-romantic relationships?▼
Absolutely! While it's designed for romantic compatibility, Venus and Moon aspects also influence friendships, family bonds, and business partnerships. The passion dimension is most specific to romance.
