Margaret Hamilton’s zodiac sign and chart, in brief
Margaret Hamilton was born on Monday, 17 August 1936, in Paoli, Indiana. That makes Margaret a Leo. The Moon was in Leo until about 08:45 and in Virgo afterwards, so the Moon sign turns on the birth time. Margaret turns 90 in 2026. No verified birth time is on file for Margaret; the chart is cast for midday, without houses.
By element the count is four earth, three fire, two water and no air, leaving out the Moon, whose sign depends on the birth time. By modality the count is five mutable, three fixed and one cardinal. Mercury, Venus and Neptune all fall in Virgo. No two planets sit closer to an exact angle than Mercury and Neptune: a conjunction, about 0.4° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Saturn and Uranus were retrograde. Over the course of the day the Moon went from new to waxing crescent.
StarMap's dataset holds 24 other people born on 17 August, among them Robert De Niro, Thierry Henry and Sean Penn.

Margaret Hamilton’s Sun, Moon and rising sign
Sun sign
Leo
about 24° Leo at midday
A Leo Sun shines. For Margaret Hamilton that suggests warmth, generosity and a need to be seen for who they really are, running through much of what they do. This placement grows by learning that the light is not diminished when it is shared.
Moon sign
Leo or Virgo
Leo until about 08:45, then Virgo (local time). Which one depends on a birth time StarMap does not have.
Born before about 08:45: Moon in Leo
A Leo Moon feels with its whole heart and needs that to be noticed. Warm attention tends to fill Margaret up, and being overlooked can empty them faster than anything. Play, creativity and loyal friends usually bring them back to themselves.
Born after about 08:45: Moon in Virgo
A Virgo Moon feels by fixing. When something is wrong, Margaret is likely to look for the practical cause and to calm down by tidying, planning or being useful. The lesson of this Moon is to accept help without a to-do list attached.
Rising sign
The rising sign changes about every two hours, so it cannot be known without a birth time. The table below shows which sign was rising over Paoli, Indiana, at each hour of the day.
Margaret Hamilton’s rising sign, by birth time
StarMap has not verified a birth time for Margaret yet. It shows a birth time only when Astro-Databank rates it AA, A or B on the Rodden scale (AA from a birth certificate or record, A from the person, someone close to them or a news report, B from a biography). Until then, this is the rising sign for every possible time of birth on 17 August 1936, computed for Paoli, Indiana.

Margaret Hamilton’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Margaret Hamilton’s private life.
Purpose for Margaret Hamilton is probably tied to creating and being seen doing it, and a Leo Sun's vitality rises the moment there is an audience, even an audience of one. The tension is losing steam when no one is watching. The giveaway is often the extra effort that goes into something the moment someone notices them making it.
Moon in Leo or Virgo
Leo until about 08:45, then Virgo
needs and habits
Born before about 08:45: Moon in Leo
A Leo Moon needs warmth and acknowledgement worked into everyday life, not just on big occasions. A day with no one noticing can drain Margaret faster than a hard day with an audience. The mood tends to lift visibly the moment someone compliments something small Margaret did.
Born after about 08:45: Moon in Virgo
The Moon in Virgo runs towards order, and a messy space or an unfinished list can unsettle Margaret's mood more than most people would guess. Small, useful tasks are calming. The trouble can start when Margaret's own needs become another chore to get right instead of something to enjoy.
For Margaret, Mercury in Virgo points to thinking that is precise and attentive to detail, and to clear communication, because the facts have usually been checked first. The catch is fixating on a small error and losing sight of the larger point. This is the placement that edits a message three times before sending something everyone else would have sent in one go.
With Venus in Virgo, Margaret is likely to love through small, practical acts of service and to value competence and reliability in a partner. People with this Venus tend to be hardest on those they love most, and can mistake giving notes for giving care. They may try to fix a partner's problem before simply listening to it.
Mars in Leo acts with confidence and wants the effort to be visible, and for Margaret its anger is likely to flare when pride or loyalty is challenged. The tension is turning a disagreement into a matter of ego. Criticism of the work can feel personal to a Leo Mars, even when it was not meant that way.
Jupiter in Sagittarius
14° Sagittarius 38' at midday
growth and excess
With Jupiter in Sagittarius, Margaret is likely to grow through travel, study and direct experience of things bigger than ordinary life. The excess may be promising more than circumstances can deliver, out of optimism rather than dishonesty. This Jupiter carries a conviction that things will work out, and other people borrow it when theirs runs low.
Saturn in Pisces builds discipline around boundaries, and it usually starts from a habit of carrying feelings that belong to other people. For Margaret, the doubt is likely to take the form of guilt for protecting their own time and energy. What this Saturn works towards is a quiet, mature compassion, once it is clear that a boundary and a closed heart are not the same thing.
Uranus in Taurus
9° Taurus 35' at midday ℞
freedom, generational
Uranus in Taurus is a generational placement that Margaret shares with many people born within a few years. That generation rethinks ownership, land and what security means, often through technology that unsettles older arrangements. Personally, that may be a reluctance to prize things simply because an older generation did.
Neptune in Virgo
15° Virgo 41' at midday
imagination, generational
Neptune moves slowly, so Margaret shares its place in Virgo with people born years either side. The imagination of this generation turns towards service, craft and idealised routines of self-improvement. In one life it can mean chasing an impossibly perfect daily practice.
Pluto in Cancer
27° Cancer 43' at midday
power, generational
Pluto in Cancer dates Margaret to an era rather than describing one person. Those born in it live through deep transformation of family, home and nationhood. What an individual may carry is intensity around belonging and who counts as family.
Aspects in Margaret Hamilton’s chart
How the planets stand to each other, tightest first. Without a birth time the orbs are those at midday, and aspects to the Moon are left out because the Moon moves about thirteen degrees in a day.
Mercury conjunction Neptune
about 0.4° at midday
With Mercury conjunct Neptune, Margaret Hamilton's thinking is likely to be imaginative and impressionistic, working through images and instinct as much as straight logic. It is a creative and intuitive strength, at its best when a compelling idea has been held up against the facts before being embraced.
Jupiter square Neptune
about 1.0° at midday
Jupiter square Neptune lets optimism drift into wishful thinking, and plans can end up built more on hope than on a clear reading of the situation. For Margaret the answer may be to keep hoping and to pair that hope with an honest look at the details.
Venus trine Uranus
about 1.4° at midday
Closeness does not have to feel confining for Margaret, because under this trine affection and independence sit easily together. Excitement and stability manage to coexist, more comfortably than the usual choice between the two would suggest.
Mercury square Jupiter
about 1.4° at midday
Thinking can run ahead of the evidence when Mercury is square Jupiter, leading to overconfident claims or promises made faster than Margaret can check them. Matching enthusiasm to what has been verified makes their confidence more durable, not less.
Mars square Uranus
about 4.9° at midday
This square can make drive turn abrupt, leading to sudden decisions or breaks that surprise Margaret as much as they surprise everyone nearby. A brief pause before the impulsive move keeps the courage and loses the recklessness.
Mercury opposition Saturn
about 4.9° at midday
Under Mercury opposite Saturn, a doubt can creep into Margaret's thinking about whether it is good enough to share. Speaking the imperfect version out loud matters more than waiting for the polished one.
The rest, listed without a reading. Those between Uranus, Neptune and Pluto hold for years at a time, so everyone born while one holds shares it.
