This page compares Sun, Mercury, Venus and Mars, the four placements a birth date alone can place. Moon, Ascendant and Midheaven are left out here by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.

The overlap
Two charts, laid over each other
Cher and Sonny Bono's Sun, Mercury, Venus, Mars and Moon are drawn here, along with the house ring and ascendant axis both charts support. This is a complete chart of what is known, not a partial chart of what is not.

Why they click
Three Venus trines carry the warmth here: Venus to Sun, Venus to Mercury and Venus to Mars, all inside two degrees. One person's capacity for affection reaches the other's identity, thinking and drive at the easiest angle the engine measures. That is an unusually even spread. Where many pairings have one warm contact, this one has affection touching three separate parts of the other chart, which reads as a bond that is comfortable across several registers at once.
Why they clash
Identity is the top category, and it is built on Sun square Sun at 1.49 degrees. A square between two Suns is the angle of two people who cannot ignore each other and cannot easily merge either. Sun square Mercury repeats it at just over a degree. Communication, friction and values all sit at the floor, so almost nothing outside those Venus trines and the Sun tension is registering. The picture is a strong personal charge with little shared ground underneath it.
What each system says
Twelve systems, two people
The Suns are 91.5° apart, close enough to feed the identity category above.
Dog and Pig are in neither the trines nor the clashes.
Guna Milan: 17.5 of 36
A second tradition
Guna Milan (Ashtakoot)
Guna Milan is the compatibility method used in Vedic matchmaking, traditionally consulted before an arranged marriage. It scores eight factors between two Moon placements on a 36-point scale, shown here as what this one tradition reads: not a verdict, and not averaged with the Western reading above, which may disagree.
17.5 of 36 points
Two things stated plainly rather than left silent: Varna and Vashya use a directional rule from traditional bride/groom roles, applied here in the order the two people are listed on this page rather than assigning either role. Bhakoot dosha's most common cancellation, matching rashi lords, is applied; Nadi dosha carries no cancellation here, though same-nakshatra-different-pada is sometimes cited elsewhere as easing it. Mangal (Kuja) dosha is a separate check and isn't part of this reading.
