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
Britney Spears and Colin Farrell's Sun, Mercury, Venus and Mars are drawn here, the four placements a birth date alone can place with no birth time required. This is a complete chart of what is known, not a partial chart of what is not.

Why they click
The precision here is unusual. Venus trine Mercury sits at 0.12 degrees, Mercury opposite Venus at 0.47, Sun opposite Sun at 0.54. Three contacts inside two-thirds of a degree is rare in any synastry. Four trines run through Mars and Mercury, describing a genuinely easy line between one chart's drive and the other's thinking. Identity scores highest of the five, built on that near-exact Sun opposition.
Why they clash
An opposition between two Suns half a degree from exact is the defining feature, and oppositions describe people positioned directly across from each other rather than beside. Mercury and Sun both take oppositions from the other chart too. Communication, attraction, friction and values all sit at the floor, so despite eight aspects the engine finds weight in only one category. Precise contact, narrow in what it touches.
What each system says
Twelve systems, two people
The Suns are 179.5° apart, close enough to feed the identity category above.
Rooster and Dragon are in neither the trines nor the clashes.
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.
Guna Milan needs an exact birth time for both people. The Moon changes nakshatra roughly once a day, so an estimated time can place the whole reading in the wrong one, and at least one birth time here isn't exact.
Frequently asked
Are Britney Spears and Colin Farrell astrologically compatible?
Their charts make 8 cross-aspects, the tightest at 0.12° and 0.47°. Astrology does not score a relationship out of a hundred, and the number on this page counts how much contact two charts make, not how well two people do.
Why isn't there a house ring on the chart above?
At least one of Britney Spears and Colin Farrell doesn't have a curated, non-estimated birth time, so a house placement would be a guess. This page only shows what a birth date alone can place.
What does opposition mean between two charts?
An opposition puts two placements directly across the chart, a pull between two poles that has to be balanced rather than resolved. Britney Spears and Colin Farrell have 4 opposition contacts between them, more than any other type.
