On this page, you can calculate astrological compatibility (a synastry horoscope) with your romantic or business partner. Simply enter both birth dates and click the «Calculate compatibility!» button. Our system will analyze the planetary positions at the time of birth and provide a detailed description of the relationship's main aspects.
Compatibility largely depends on the angular distance between the partners' Suns. The best compatibility occurs when the angle is close to 120 degrees (trine), which happens when they are in signs of the same element (e.g., Taurus and Virgo — both are earth signs). Another excellent aspect is 60 degrees (sextile), such as between Scorpio and Capricorn, or Taurus and Cancer. The closer the angle is to 120 or 60 degrees, the better the compatibility and the deeper the connection. The exactness of the aspect also affects how closely and intensely the partners relate to each other.
Aspects of 180 (opposition) and 90 degrees (square) create tension. For example, Gemini and Sagittarius (180°) or Libra and Cancer (90°) may experience contradictions. A conjunction (an angle near 0 degrees) is not bad, but can be slightly one-sided. However, even challenging aspects forge a strong bond, offering a unique potential for deep interaction and growth.
A crucial factor is the connection between one partner's Sun and the other's Moon. This aspect significantly increases relationship stability and the likelihood of marriage, or indicates a highly productive business partnership.

The "romantic" horoscope focuses on the "love" planets — Mars and Venus. The positions of Venus and Mars are paramount for love and romance. A strong romantic feeling is highly likely to occur between partners when their Venus and Mars are in conjunction. Romantic feelings are also aroused by other accurate aspects involving Mars or Venus.
Venus represents how we express love, affection, and values. Mars represents how we pursue desires, passions, and sexual energy. When Venus and Mars are in harmony in a synastry chart, partners enjoy a satisfying and exciting relationship. They share feelings openly, respect each other’s preferences, and fulfill each other’s needs. However, when Venus and Mars are in conflict, partners may experience frustration, jealousy, or boredom, often clashing over different expectations or rhythms in love.
Lilith is another factor affecting compatibility. Lilith is the dark and mysterious point representing hidden desires, fears, and impulses. It can bring out the wild, intense, and taboo side of our sexuality. Lilith aspects in synastry can create a powerful, almost magnetic attraction. Harmonious aspects indicate a deep acceptance of each other’s shadow side, allowing partners to explore fantasies without judgment. Challenging aspects can indicate a turbulent attraction that is both thrilling and destructive, potentially triggering issues around power, control, or obsession.
