Tight and uncounted
Magic Johnson and Larry Bird compatibility
↓ Below: all 5 aspects named, with orbs
No birth time on record, so houses and the rising sign are not shown.
Note on this rating: Date and birthplace confirmed independently via Wikidata (P569/P19, precision to the day) and English Wikipedia. No reliable birth time is on public record, so none is asserted here.
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
Magic Johnson and Larry Bird'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
Johnson's Mars squares Bird's Sun at three tenths of a degree, and his Venus squares the same Sun at just over half a degree. Those are the two tightest contacts between the charts by a wide margin, and both fall outside the five pairings the score tracks, so neither moves a single category.
Why they clash
What does count is softer and wider. Attraction reads 51 on a Mars sextile Venus within a degree, values 48 on the two Venuses a little over a degree apart, and identity drops to 23 on a Sun trine Sun five and a half degrees wide. That last figure sits below the 30 the engine returns for no contact at all, because a soft aspect starts at 20 and has to earn its way up with tightness.
What each system says
Twelve systems, two people
The Suns are 114.4° apart, close enough to feed the identity category above.
Pig and Monkey 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 Magic Johnson and Larry Bird astrologically compatible?
Their charts make 5 cross-aspects, the tightest at 0.3° and 0.54°. 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 Magic Johnson and Larry Bird 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 square mean between two charts?
A square puts two placements at a right angle, generating friction that tends to force action. Magic Johnson and Larry Bird have 2 square contacts between them, more than any other type.
Exact, and all soft
Read the relationship as one chart
This page compares Sun, Mercury, Venus and Mars, because those are the four that a birth date alone can place. With no hard contact between the two, a composite chart, the midpoint of both, often reads clean.
