Synastry charts are used to compare the astrological birth charts of two people in order to assess their compatibility. While these charts can provide insight into potential areas of conflict and harmony between two individuals, it is important to remember that they should not be taken as absolute truth. Ultimately, how accurate a synastry chart is depends on the accuracy of the birth data provided for each individual and how well an astrologer interprets this information. Synastry charts offer useful guidance but should not be seen as definitive answers about relationships or life paths.
