What the chart says
Jeffrey, according to the stars
Core essence
Jeffrey is the steady one, the person whose yes means yes and whose Sunday looks the same as it did last year because it was a good Sunday. The core of Jeffrey is a deep loyalty to what is real: good food, a good bed, people who show up. They move slowly on purpose. Once they have decided something, it is decided, and that is a comfort to everyone around them.
The vibe
Underneath, Jeffrey is steadier than they let on and more tender than they let on, both at once. The Moon in Capricorn feels deeply and privately, and would rather fix the problem than talk about the feeling. What Jeffrey needs to feel safe is reliability and respect. They soften completely for the people who earn it.
How Jeffrey wants to be loved
Jeffrey wants to be loved boldly. Venus in Aries falls fast, says so, and wants you to chase back. Grand gestures land, so does a fight followed by a proper make-up. What bores them is hesitation. Be direct, be a little brave about them, and keep the spark lit on purpose.
How Jeffrey creates
How Jeffrey makes things happen: they keep moving. A Yang Water day master is the river, curious, restless, going somewhere even when nobody knows where. Jeffrey creates by exploring, by talking to everyone, by carrying ideas from one place to another. Hard to pin down, impossible to dam, and the best person to have on a long trip.
Instinct
Instinct: Jeffrey is sharp and confident, a Rooster year, and their gut reaction is to say the true thing out loud. Observant, hardworking, honest, and proud of looking the part. The Wood year adds growth: ideals, ambition, a need to be getting somewhere.
Purpose
Purpose: Life Path 9 is the humanitarian. Jeffrey is here for the bigger picture, to give, to finish what others started and hand it on. Wise beyond their years, compassionate, a little world-weary, and learning to receive as freely as they give.
Triggers
Triggers: being told to wait. Mars in Aries means Jeffrey gets angry fast, says it, and is over it before you have finished being hurt. The temper is honest and short. Give them a clear path and something to fight for, and all that heat turns into drive.

Three stars chosen from the real sky above Brooklyn on the night they were born. Choose the story that connects you.
No public birth time is available, so this is a 9:00 p.m. reference evening sky for that date and place. It is connected to the night of birth; it is not the sky at the birth minute, and no other reading on this page uses that time. Dedications are commemorative AsterNym records and do not rename or confer ownership of stars.
Taurus Sun
Taurus SunBuilt for the long haul.
Jeffrey C. Hall's Sun was in Taurus for the whole of May 3, 1945, so no birth time is needed to settle it. Traditional Taurus readings associate the sign with steadiness, sensory pleasure and things that last. Astrologers describe it as the fixed earth sign, ruled by Venus, and read it for loyalty, routine and a slow, deliberate pace. The corresponding tension is resistance to change, described in the tradition as stubbornness that presents itself as principle.
Wood Rooster
Wood RoosterPunctual, precise, proud.
Jeffrey C. Hall was born on May 3, 1945, which falls in a Wood Rooster year of the Chinese calendar. Traditional Rooster readings emphasise precision, candour and pride in appearance and in work done properly. The Chinese almanacs describe the Rooster as observant and punctual, the sign that notices and says so. The corresponding caution in the tradition is vanity, and a frankness that arrives before anyone asked for it.
Life Path 9
Life Path 9Compassion at scale.
Jeffrey C. Hall's birth date, May 3, 1945, reduces to Life Path 9 under the numerology method AsterNym uses. Traditional Life Path 9 readings associate the number with compassion, generosity and completion: a wide view that takes in more than one person's experience. Numerologists describe it as the path of the humanitarian, the last single digit and the one that closes cycles. The corresponding tension is diffuseness, with the caution that caring about everyone can be easier than showing up for someone.

Jeffrey’s birth chart
Reference chart · birth time unknown
No documented birth time exists for Jeffrey C. Hall, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 17° to 29° Capricorn depending on the hour. The wheel's houses are a solar chart, counted from the Sun's sign, because the Ascendant needs a time.
No birth time, so the houses are a solar chart: the Sun’s sign counts as house 1. A documented time would place them from the Ascendant instead.

Jeffrey’s Chiron, Ceres, Eros, Hygiea and Lilith
Four minor bodies and the mean lunar apogee, placed in the same tropical zodiac as the planets above. None of these feed the chart signature, the rarity score or any ranking on this site: they are listed for readers who use them. Chiron, Ceres, Eros and Hygiea positions come from JPL Horizons; Black Moon Lilith is the mean apogee, the point most published Lilith tables use. The readings are the modern tradition’s, not AsterNym’s. Without a birth time the degree is the noon value and the day's movement is shown alongside it.
⚷ Chiron ℞Virgo 27°23′ (moves 0.04° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Virgo is read as a wound around never being good enough. The reading has Jeffrey turning that pressure into craft and an eye for what others miss.
⚳ Ceres ℞Libra 28°48′ (moves 0.21° over the day)
dwarf planet (1) · how a person nurtures and wants to be nurtured
Ceres in Libra is read as nurture through fairness and company. Jeffrey is read as someone who feeds others by keeping the peace and the balance.
♡ ErosLeo 11°11′ (moves 0.89° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Leo is read as desire that wants to be adored and to adore in return. The reading has Jeffrey loving with an audience in mind, even an audience of one.
⚕ HygieaAquarius 14°04′ (moves 0.20° over the day)
main-belt asteroid (10) · health, routine and what keeps them well
Hygiea in Aquarius is read as health through the unconventional: odd hours, own methods. Jeffrey is read as someone who ignores the standard advice and sometimes proves it wrong.
⚸ Black Moon LilithLibra 19°05′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Libra is read as the part of Jeffrey that will not keep the peace at the price of the self. Fairness, on these terms, is not the same as niceness.
Aspects to the asteroids and Lilith
Major aspects only, at a tight 3° orb. The Moon is left out because its position moves 13° across an untimed day.
- Eros sextile Uranus 0.2°
- Black Moon Lilith opposition Mercury 0.6°
- Hygiea square Sun 1.2°
- Eros square Sun 1.6°
- Black Moon Lilith opposition Venus 1.7°
- Hygiea trine Uranus 2.6°
Method: JPL Horizons heliocentric vectors, 1700–2100, cubic Hermite interpolation; geocentric, true ecliptic of date, tropical; geometric (no light-time or aberration); Lilith = mean lunar apogee (Chapront/Meeus mean perigee + 180°).
Jeffrey’s dominant planets
Scored from rulerships, dispositors and aspect count. Without a birth time there is no Ascendant or house to score, and the Moon's sign is left out where it could change with the hour.
1. ♀ Venus6 pts
rules the Sun sign, Taurus; disposes Sun, Neptune; 1 major aspect
2. ♂ Mars6 pts
in its own sign, Aries; disposes Mercury, Venus; 2 major aspects
3. ☉ Sun3 pts
disposes Pluto; 2 major aspects
A Venus-led chart is read as taste and relationship setting the terms: Jeffrey is read as choosing by what is beautiful and who is in the room.
How the score is built
- Rules the Sun sign, Moon sign or Ascendant sign: 3 points each (traditional co-rulers of Scorpio, Aquarius and Pisces score half).
- Sits in a sign it rules: 2 points.
- Disposes another planet (that planet sits in a sign it rules): 1 point each.
- Angular: 2 points in the first or tenth house, 1 point in the fourth or seventh (timed births only).
- Every major aspect it makes: 1 point.
Dominance scoring is an AsterNym method. Other sites weight differently and can name a different leader for the same chart.
Configurations in Jeffrey’s chart

Where this data comes from
Jeffrey’s birth date and birthplace come from Wikidata Q1686435, released under CC0, as do the occupations, works, teams and awards in the biography above. No documented birth time is available, so this chart is rated X on the Rodden scale, the astrological convention for how well evidenced a birth time is. Time-dependent results use a clearly labelled reference time and should not be read as their exact birth chart. Entries are matched to Wikidata by entity id rather than by name, kept only at day precision, and dropped where sources disagree on the date.
