How are two charts compared?

Each birth chart is calculated independently and cross-chart angles are listed. There is no scientifically validated compatibility score. Real relationship choices depend on respect, behavior and communication, not planetary positions.

Important accuracy note

These estimates are for cultural and entertainment exploration, not reference astronomy. Verify positions near zodiac boundaries using a specialist ephemeris. The calculator uses tropical zodiac signs and supports 1900–2100.
