Guide
How compatibility is evaluated
Compatibility is strongest when one quick score is supported by emotional fit, communication rhythm, attraction style, and long-term context.
What is compared
Sign tools compare selected signs. Exact tools compare two birth charts. Kundli matching should verify Nakshatra, Guna Milan, Manglik context, and timing.
Score logic
The score is a high-level summary of ease and friction. Read it together with the notes, placements, and relationship themes beneath it.
Depth
Moon, Venus, Mars, synastry, and complete Kundli context add depth when the relationship question needs more than one matching layer.
Emotional compatibility
Moon signs, Moon aspects, Nakshatra context, and daily care patterns show how safe and understood the bond may feel.
Communication
Mercury, element balance, pacing, conflict style, and repair habits matter more than a single attraction score.
Attraction
Venus, Mars, chemistry indicators, and mutual responsiveness describe desire more clearly than Sun signs alone.
Long-term potential
Shared values, seventh-house themes, timing cycles, family expectations, and real behavior keep the reading practical.

Use this section before and after the result: first to understand what the tool measures, then to interpret the answer with context.
What it does
This calculator compares two birth charts to explore relationship patterns. It looks beyond Sun signs into emotional fit, attraction, communication, and areas that may need more understanding.
Input required
Use accurate birth details for both people when available. Exact birth time improves Moon, house overlay, and angle-based relationship context.
How it works
The calculator compares core chart factors and relationship indicators, then turns them into a readable compatibility overview. It is designed to show patterns, not decide a relationship for you.
Why it matters
Many astrologers compare the Moon, Venus, Mars, Mercury, angles, houses, and synastry aspects when reading relationships. A complete chart gives a fuller picture than one sign match.
Traditional meaning
Traditional relationship reading often considers the seventh house, its ruler, Venus, Mars, the Moon, and condition of relevant planets. Modern synastry adds detailed cross-chart aspect interpretation.
Reflection use
Use the result to start better conversations. Focus on one strength to appreciate and one difference to handle more consciously.
Beginner mistakes to avoid
- Treating a score as the relationship's fate.
- Using only Sun signs when birth details are available.
- Ignoring communication, timing, and real-life behavior.
Limits to keep in mind
- Compatibility tools cannot replace honest conversation or lived experience.
- If one birth time is missing, house and angle comparisons are less complete.
