Astrology Compatibility Calculator

Check your astrological compatibility for free. Compare Sun, Moon, and Rising signs to discover relationship strengths, challenges, and your overall compatibility score.

How the compatibility calculator works

Enter the birth details for both people — date, time, and location. The calculator generates full birth charts for each person and compares them across multiple dimensions:

• Sun sign compatibility — core identity and life direction alignment
• Moon sign compatibility — emotional resonance and inner needs
• Rising sign compatibility — first impressions and social chemistry
• Element harmony — Fire, Earth, Air, Water balance between charts
• Overall compatibility score — combined assessment of all chart factors

After your compatibility reading

Once you have your compatibility score, you can take that data directly into the AI chat to ask deeper questions about the relationship — what the tensions mean, how to work with differences, and what the connection is really about.
