Birth data: X

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

Bill Gates’s Mercury and Paul Allen’s Mars are 0.08 degrees from an exact quincunx.

Quincunx · Hard · orb 0.08° · tightest of 42 contacts

Paul Allen’s birth time is not exact, so the Moon is not scored and the ascendant axis and house ring are not drawn for either chart. Sun through Pluto move at most about two degrees in a day, so every contact below is the same whatever the time.

31 of the 42 contacts fall between Sun and Pluto, and all 31 are in the grid. A boxed cell is within one degree. The other 11 contacts involve Chiron and the lunar nodes and are listed below, 2 of them in the tight layer.

A cell is a plain glyph. The aspect it names is a Codex Link in the sentences above.

Shared generation

Jupiter 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

The tightest contact between these two charts is Gates's Mercury quincunx Allen's Mars, eight hundredths of a degree from exact. Mercury to Mars is not one of the five pairings the engine tracks, so that near-perfect angle contributes nothing to any category. What carries the score is a Sun square Sun just under four degrees wide, which reads 75.

Why they clash

Communication and friction both return 30. Neither the two Mercuries nor the two Marses make an angle, so there is nothing on either axis to measure. Values reads 44 and attraction 36, both on trines wide enough to keep them near the bottom of the range. Six contacts, and a single hard aspect among them.

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.

Editorial note · Neptune sextile Mars

Neptune sextile Mars in the fifth house peaked 102 days before the launch, marking a potent power window where imaginative technical ambition first aligned behind the scenes to shape their new venture.

Editorial note · Uranus square Sun

Uranus squared the Sun 109 days before the founding, marking a volatile power window that set the stage for radical reinvention.

Bands are drawn against a ±180-day window centred on the event date. Passages that run past the window carry an open cap. Marked ■ = slow-planet contact.

Frequently asked

Are Bill Gates and Paul Allen astrologically compatible?

Their charts make 42 cross-aspects, the tightest at 0.08° and 0.27°. 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 Bill Gates and Paul Allen 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. Bill Gates and Paul Allen have 13 square contacts between them, more than any other type.
