What the chart says
Willem, according to the stars
How Willem wants to be loved
Willem wants to be loved like home. Venus in Cancer needs to feel safe before it feels anything else, and then it feels everything. Remember the small things, meet the family, make the tea. Willem gives care in a hundred quiet ways and needs to know it is noticed. Consistency is the romance.
How Willem creates
How Willem makes things happen: they find the gap and grow through it. A Yin Wood day master is the vine, flexible, quietly relentless, better at working around a wall than at knocking it down. Willem creates by adapting, by connecting people, by making the awkward thing fit. Underestimate them and you will look up one day to find them everywhere.
Instinct
Instinct: Willem is witty and inventive, a Monkey year, and their gut reaction is to play with the problem. Clever, funny, curious, a little mischievous, and quick to land on their feet. The Metal year sharpens it: principled, determined, clear about what is right.
Purpose
Purpose: Life Path 5 is the free spirit. Willem is here to explore, to change, to taste everything and report back. Adventure, variety and freedom are not distractions from their purpose, they are it. The lesson is choosing, sometimes, and staying.
Triggers
Triggers: incompetence, and disrespect. Mars in Capricorn means Willem does not waste energy on anger; they use it. Controlled, strategic, relentless, the person who will outlast the problem. Cold when crossed, and quietly forgiving once you have earned it back.

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.
The quick version
Taurus or Gemini Sun
Willem Einthoven was born on a day when the Sun moved from Taurus into Gemini. Without a documented birth time, the exact Sun sign cannot be determined reliably, so AsterNym shows both rather than choosing one.
Metal Monkey
Metal MonkeyClever, playful, never bored.
Willem Einthoven was born on May 21, 1860, which falls in a Metal Monkey year of the Chinese calendar. Traditional Monkey readings emphasise ingenuity, wit and the ability to find unconventional solutions to problems others have given up on. The Chinese almanacs describe the Monkey as the cleverest sign in the cycle, playful and quick. The corresponding caution in the tradition is mischief, and a trick played one time too many on the wrong person.
Life Path 5
Life Path 5Change finds them anyway.
Willem Einthoven's birth date, May 21, 1860, reduces to Life Path 5 under the numerology method AsterNym uses. Traditional Life Path 5 readings associate the number with freedom, change and variety: movement, new experience and resistance to restrictive routine. Numerologists describe it as the path of the traveller, adaptable and restless. The corresponding tension is instability, with the caution that constant motion can become a way of avoiding commitment to any one direction.
What stands out in Willem’s chart
- The tightest major aspect in Willem Einthoven's date-only chart is Sun sextile Neptune, with an orb of about 1°.
Willem’s birth chart
Reference chart · birth time unknown
No documented birth time exists for Willem Einthoven, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 28° to 12° Taurus or Gemini 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.

Counted across the ten planets by sign.
Willem’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.
⚷ ChironAquarius 27°38′ (moves 0.01° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Aquarius is read as a wound around fitting in. The tradition has Willem making a place among outsiders and keeping the door open for the next one.
⚳ CeresTaurus 10°42′ (moves 0.40° over the day)
dwarf planet (1) · how a person nurtures and wants to be nurtured
Ceres in Taurus is read as nurture through the physical: food, comfort, a steady presence. Willem is read as someone who shows care by providing.
♡ ErosTaurus 27°08′ (moves 0.84° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Taurus is read as desire through the senses and through time. The reading has Willem wanting what can be touched, kept and returned to.
⚕ HygieaVirgo 14°32′ (moves 0.12° over the day)
main-belt asteroid (10) · health, routine and what keeps them well
Hygiea in Virgo sits in the sign the tradition links to it most closely: health as maintenance. Willem is read as attentive to small signals and prone to over-attending.
⚸ Black Moon LilithPisces 12°30′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Pisces is read as a refusal to be reasonable about longing. Willem is read as someone whose imagination goes where it is not invited.
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.
- Black Moon Lilith sextile Mercury 0.1°
- Hygiea sextile Venus 0.6°
- Eros trine Mars 0.9°
- Ceres conjunction Mercury 1.7°
- Eros sextile Neptune 1.8°
- Hygiea trine Mercury 2.1°
- Ceres conjunction Pluto 2.2°
- Chiron square Sun 2.7°
- Black Moon Lilith trine Venus 2.7°
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°).
Willem’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. ☿ Mercury7 pts
rules the Sun sign, Gemini; disposes Sun, Uranus; 2 major aspects
2. ♆ Neptune5 pts
in its own sign, Pisces; 3 major aspects
3. ☉ Sun4 pts
disposes Saturn; 3 major aspects
A Mercury-led chart is read as the mind in charge: Willem is read as thinking, talking and connecting their way through life.
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 Willem’s chart
Closed shapes among the ten planets under the site’s one aspect-orb policy. The Moon is excluded without a birth time, so a shape that needs it is not claimed.
No stellium, grand trine, T-square, grand cross, yod or kite closes among the planets that can be placed. That is the common case, not a gap.
Minor aspects
semi-sextile 30° (orb 2°), semi-square 45° (orb 2°), quintile 72° (orb 1.5°), sesquiquadrate 135° (orb 2°), biquintile 144° (orb 1.5°), quincunx 150° (orb 2.5°). Pairs already in a major aspect are not repeated. Moon excluded without a birth time.
- Sun semi-square Venus 0.1°
- Jupiter semi-square Uranus 0.1°
- Saturn quintile Uranus 0.6°
- Uranus semi-sextile Pluto 1.2°
- Mercury semi-square Neptune 1.5°
Houses need a birth time. None is documented for Willem Einthoven, so no house placements are claimed for the planets or the minor bodies above.

No birth time is on public record for Willem Einthoven, so this chart has three pillars rather than four. The hour pillar, the rising sign and the birth-sky star all need a time, and we would rather leave them out than invent one.
Where this data comes from
Willem’s birth date and birthplace come from Wikidata Q189488, 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.

Quick answers about Willem Einthoven’s chart
- What zodiac sign was Willem Einthoven?
- Willem Einthoven was born on a day when the Sun moved from Taurus into Gemini. Without a documented birth time, the exact Sun sign cannot be determined reliably, so AsterNym shows both rather than choosing one. In the Chinese zodiac they were a Metal Monkey.

- The Monkey, with the Metal element, from the Chinese lunar year of the May 21, 1860 birth.
- What time was Willem Einthoven born?
- No reliably documented birth time is public, so AsterNym does not calculate an Ascendant. This chart uses date-only positions: the wheel shows a reference solar chart (the Sun's sign as house 1), and the Ascendant is left uncomputed instead of guessed from an unverified time.
- What was Willem Einthoven's Life Path number?
- Life Path 5, calculated in numerology from the May 21, 1860 birth date.

- Chiron in Aquarius at 27°. Position from JPL Horizons for the May 21, 1860 birth date.

- What was Willem Einthoven's dominant planet?
- Mercury, on AsterNym's dominance score (7 points: rules the Sun sign, Gemini; disposes Sun, Uranus; 2 major aspects). Neptune is second and Sun third. Other sites weight rulerships and aspects differently and can name a different leader.
