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 the nine bodies a birth date alone can place, Sun through Pluto, and lists the Chiron and lunar node contacts alongside them. The Moon is drawn as the span it could have moved through and is scored in nothing here; the ascendant axis and the house ring are left out by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.
The overlap
Where the two charts touch
Magic Johnson’s Mercury and Larry Bird’s Chiron are 0.20 degrees from an exact opposition.
Neither birth time here is exact, so the Moon is not scored against anything and the ascendant axis and house ring are not drawn. Sun through Pluto move at most about two degrees in a day, so every contact below is the same whatever the time. This is the whole of what a birth date can place, not a sample of it.

22 of the 34 contacts fall between Sun and Pluto, and all 22 are in the grid. A boxed cell is within one degree. The other 12 contacts involve Chiron and the lunar nodes and are listed below, 1 of them in the tight layer.
A cell is a plain glyph. The aspect it names is a Codex Link in the sentences above.
Magic Johnson inner ring, Larry Bird outer ring, with the contacts inside one degree drawn. 6 of them are between Sun and Pluto; the rest involve bodies that are not on either ring.

Shared generation
7 of 34Jupiter through Pluto on both sides. Born 3 years apart, these two have their outer planets in nearly the same degrees, so anyone born near them shares most of this group. Listed because it is real, kept apart because it says little about the pair.

Trines and sextiles are soft, squares, oppositions and quincunxes hard. A conjunction depends on which two bodies meet, so it carries no tone here.
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
This is what comparing two charts system by system looks like: the same birth data on both sides, read against each other one system at a time.
The Suns are 114.4° apart, close enough to feed the identity category above.
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.

Frequently asked
Are Magic Johnson and Larry Bird astrologically compatible?
Their charts make 34 cross-aspects, the tightest at 0.2° and 0.3°. 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 10 square contacts between them, more than any other type.
