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.
Cross-aspects
Where the two charts actually touch
The overlap
Two charts, laid over each other
Justin Trudeau and Katy Perry'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.
| Thick line, Venus to Sun | SQUARE 1.13° |
| Thin line, Sun to Sun | SEXTILE 1.28° |

Why they click
Sun sextile Sun at 1.28 degrees is the clearest contact, and identity scores highest of the five categories because of it. A sextile between two Suns describes people who find each other easy company without being especially alike, an angle of opportunity rather than fusion. Venus sextile Venus supports it with a compatible sense of taste. Where this pairing works, it works lightly and without much friction.
Why they clash
Venus square Sun at 1.13 degrees is the sharp note, and it cuts across the easy Sun contact: one person's affection meeting the other's identity at a hard angle. Mars quincunx Sun adds an adjustment on top. Communication, attraction, friction and values all sit at the floor, so almost nothing here is registering strongly in either direction. On this scale the chart describes a connection that is pleasant and shallow rather than difficult.
What each system says
Twelve systems, two people
The Suns are 61.3° apart, close enough to feed the identity category above.
Pig and Rat are in neither the trines nor the clashes.
Guna Milan: 6 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.
6 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.
