What the chart says
Jan, according to the stars
Core essence
Jan feels everything, and it is the best and hardest thing about them. The core of Jan is imagination with a soft heart behind it: the daydream, the creative pull, the instinct that knows how someone is doing before they do. They absorb the mood of a room and give back something kinder. Their softness is not weakness, it is the whole point.
How Jan wants to be loved
Jan wants to be loved as a friend first, and then as everything. Venus in Aquarius needs freedom, conversation and a partner who finds their strangeness delightful. Rules and jealousy make them cold; acceptance makes them devoted. Let Jan be fully themselves and they will never want to be anywhere else.
How Jan creates
How Jan makes things happen: they light the room. A Yang Fire day master is the sun, warm, visible, impossible to ignore, generous with energy and expecting the same back. Jan creates in front of people and is at their best with an audience and a cause. The work is learning to rest before the fire does it for them.
Instinct
Instinct: Jan is larger than life, a Dragon year, and their gut reaction is to go big. Confident, lucky, a natural at the centre of things, and warm-hearted underneath the spectacle. The Fire year turns the volume up: warmer, bolder, more expressive, harder to overlook.
Purpose
Purpose: Life Path 4 is the builder. Jan is here to make things that last, to put structure under other people's dreams, to be trusted with the real work. Loyal, practical, honest, and learning that the plan can bend without breaking.
Triggers
Triggers: being bored, and being talked over. Mars in Gemini fights with words and wins, then forgets it happened. Jan scatters energy across three projects at once and somehow finishes two. The trick is choosing the argument worth having.

Jan Koum at a glance
Pisces Sun
Pisces SunDreams in full colour.
Jan Koum's Sun was in Pisces for the whole of February 24, 1976, so no birth time is needed to settle it. Traditional Pisces readings associate the sign with imagination, empathy and permeable boundaries: absorbing the mood of a place and turning it into something. Astrologers describe it as the mutable water sign, traditionally ruled by Jupiter and in modern practice by Neptune. The corresponding tension is drift, described in the tradition as a difficulty telling one's own feelings from everyone else's.
Fire Dragon
Fire DragonConfident before the proof.
Jan Koum was born on February 24, 1976, which falls in a Fire Dragon year of the Chinese calendar. Traditional Dragon readings emphasise confidence, luck and scale: the only mythical animal in the cycle, associated with ambition and with attention that arrives whether or not it was sought. The Chinese almanacs describe the Dragon as the sign of large gestures. The corresponding caution in the tradition is arrogance, and a difficulty with tasks too small to be seen.
Life Path 4
Life Path 4Structure is comfort.
Jan Koum's birth date, February 24, 1976, reduces to Life Path 4 under the numerology method AsterNym uses. Traditional Life Path 4 readings associate the number with structure, patience and building: turning ideas into plans and plans into something that outlasts the mood that started it. Numerologists describe it as the path of the builder. The corresponding tension is rigidity, with the caution that the structure was meant to serve the life and not the reverse.
What stands out in Jan’s chart
- The tightest major aspect in Jan Koum's date-only chart is Venus square Uranus, with an orb of about 1°.
- Jan Koum combines a Fire Day Master in BaZi with a mutable Sun and a Life Path on the physical plane, the combination AsterNym calls The Radiant Explorer.

Reference chart · birth time unknown
No documented birth time exists for Jan Koum, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 23° to 6° Sagittarius or 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.

Jan’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.
⚷ ChironAries 24°45′ (moves 0.04° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Aries is read as a sore spot around asserting oneself: Jan may have learnt early that going first costs something, and built a way of leading that does not need permission.
⚳ CeresGemini 5°25′ (moves 0.21° over the day)
dwarf planet (1) · how a person nurtures and wants to be nurtured
Ceres in Gemini is read as nurture through talk and attention. The tradition has Jan feeding people with information and feeling fed by conversation.
♡ ErosPisces 1°43′ (moves 0.61° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Pisces is read as desire as dissolving: the wish to merge, and the trouble that follows. Jan is read as easily moved and hard to pin.
⚕ HygieaGemini 26°06′ (moves 0.04° over the day)
main-belt asteroid (10) · health, routine and what keeps them well
Hygiea in Gemini is read as health that lives in the nerves and the mind. The tradition has Jan needing variety and enough sleep in equal measure.
⚸ Black Moon LilithAries 12°47′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Aries is read as the refusal to be second. The modern reading has Jan carrying an anger that is cleaner than it looks and a need to act on it.
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.
- Ceres trine Venus 0.3°
- Ceres square Sun 0.5°
- Black Moon Lilith trine Neptune 1.1°
- Chiron conjunction Jupiter 1.5°
- Black Moon Lilith opposition Pluto 1.5°
- Chiron square Saturn 2.2°
- Hygiea sextile Jupiter 2.8°
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°).
Jan’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. ♆ Neptune7 pts
rules the Sun sign, Pisces; disposes Sun; 3 major aspects
2. ☿ Mercury5 pts
disposes Mars; 4 major aspects
3. ♅ Uranus5 pts
disposes Mercury, Venus; 3 major aspects
A Neptune-led chart is read as imagination and porousness leading: Jan is read as tuned to what is not said.
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 Jan’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.
- Venus sesquiquadrate Mars 0.3°
- Sun biquintile Pluto 0.4°
- Sun semi-sextile Venus 0.9°
- Mars sesquiquadrate Uranus 1.0°
- Saturn sesquiquadrate Neptune 1.9°
Houses need a birth time. None is documented for Jan Koum, so no house placements are claimed for the planets or the minor bodies above.

No birth time is on public record for Jan Koum, 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
Jan’s birth date and birthplace come from Wikidata Q15737800, 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.
Roster last reviewed September 10, 2026. Every entry is checked against its Wikidata record; where a person shares a name with someone else, the entity id is what settles which of them this is. What we will not tell you sets out the claims this site refuses to make.
