Jon Hamm’s birth chart
Born 10 March 1971, in St. Louis, Missouri. StarMap has no verified birth time yet.
Pisces Sun · Moon in Leo or Virgo
Jon Hamm’s zodiac sign and chart, in brief
10 March 1971 was a Wednesday: the day Jon Hamm was born in St. Louis, Missouri. That makes Jon a Pisces. The Moon was in Leo until about 02:10 and in Virgo afterwards, so the Moon sign turns on the birth time. Jon turns 55 in 2026. StarMap has not verified a birth time yet, so the chart is cast for midday on that date and has no houses.
Of the nine planets whose sign does not depend on the birth time, three are in fire signs, two in earth, two in air and two in water. Mutable signs hold six, fixed signs two and cardinal signs one. Mars, Jupiter and Neptune all fall in Sagittarius. Closest of the aspects is the square between Mars and Pluto, about 0.4° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Three planets were retrograde: Uranus, Neptune and Pluto. Over the course of the day the Moon went from waxing gibbous to full.
StarMap's dataset holds 20 other people born on 10 March, among them Osama bin Laden, Chuck Norris and Sharon Stone.

Jon Hamm’s Sun, Moon and rising sign
Sun sign
Pisces
about 19° Pisces at midday
A Pisces Sun feels it all. Imagination, empathy and a porous sense of where the self ends and others begin tend to make Jon Hamm the kind of person people confide in. This placement needs boundaries as much as it needs the sea.
Moon sign
Leo or Virgo
Leo until about 02:10, then Virgo (local time). Which one depends on a birth time StarMap does not have.
Born before about 02:10: Moon in Leo
A Leo Moon feels with its whole heart and needs that to be noticed. Warm attention tends to fill Jon up, and being overlooked can empty them faster than anything. Play, creativity and loyal friends usually bring them back to themselves.
Born after about 02:10: Moon in Virgo
A Virgo Moon feels by fixing. When something is wrong, Jon 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 St. Louis, Missouri, at each hour of the day.
Jon Hamm’s rising sign, by birth time
StarMap has not verified a birth time for Jon 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 10 March 1971, computed for St. Louis, Missouri.

Times are rounded to five minutes. Close to a boundary, a few minutes either way change the answer.

Jon Hamm’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Jon Hamm’s private life.
The Sun in Pisces finds purpose in imagination, compassion and things that cannot quite be measured, and Jon Hamm's vitality tends to ebb and flow with their surroundings. The thing to watch is losing their own direction inside someone else's story. There may be days when they feel unstoppable, and others when they need to disappear for a while.
Moon in Leo or Virgo
Leo until about 02:10, then Virgo
needs and habits
Born before about 02:10: 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 Jon faster than a hard day with an audience. The mood tends to lift visibly the moment someone compliments something small Jon did.
Born after about 02:10: Moon in Virgo
The Moon in Virgo runs towards order, and a messy space or an unfinished list can unsettle Jon's mood more than most people would guess. Small, useful tasks are calming. The trouble can start when Jon's own needs become another chore to get right instead of something to enjoy.
Mercury in Pisces thinks in images and impressions more than straight lines, and Jon is likely to communicate through metaphor, tone and instinct rather than clean argument. Explaining a conclusion they nonetheless feel certain about can be the struggle. It is the kind of mind that knows something is off before it can say why.
Venus in Aquarius loves as a friend first, and values independence, shared ideas and a partner who allows plenty of room. Jon may keep just enough distance that closeness feels slightly out of reach, even to them. This Venus can prize a partner's individuality more than the intimacy between them.
Mars in Sagittarius acts boldly and wants room to move while doing it, and its anger flares fast over anything that feels like a limit on freedom. Jon may speak bluntly in the heat of the moment and smooth it over later. Given the choice, this placement walks away from a fight rather than staying to work it out.
Jupiter in Sagittarius
6° Sagittarius 12' at midday
growth and excess
With Jupiter in Sagittarius, Jon 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 Taurus gathers its discipline around security and the things a person relies on, and Jon is likely to take very little for granted. The doubt is a fear that stability could disappear, even when it clearly has not. This placement likes to know what things cost before committing, and tends to stay careful even in steady times.
Uranus in Libra
12° Libra 27' at midday ℞
freedom, generational
Jon holds Uranus in Libra in common with many people born in the same stretch of years. Together that generation reshapes ideas of partnership, fairness and how relationships are arranged. Its personal side is a readiness to question traditional roles more openly than earlier generations felt able to.
Neptune in Sagittarius
3° Sagittarius 03' at midday ℞
imagination, generational
Neptune in Sagittarius is the dream of a generation: grand systems of belief and utopian journeys. What belongs to Jon in it may be a hopeful conviction that the right philosophy will resolve a practical problem.
Pluto in Virgo
28° Virgo 36' at midday ℞
power, generational
Pluto in Virgo is shared by Jon and many people born in the same span of years. That generation lives through deep change in work, in how services are organised, and in daily life itself. In one person that can be intensity around control, order and how much any one system can carry.
Aspects in Jon Hamm’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.
Mars square Pluto
about 0.4° at midday
With Mars square Pluto, Jon Hamm's drive can turn into a fight for control, whether the opponent is within them or is someone who resists them. When they redirect that intensity into the work itself, the friction becomes lasting strength.
Sun sextile Saturn
about 1.4° at midday
Steady, unglamorous effort is likely to feel worthwhile to Jon rather than draining, because it fits their sense of who they are. Consistency probably comes more easily to them than they give themselves credit for, especially once they stop waiting for permission to claim it.
Venus sextile Jupiter
about 1.5° at midday
Warmth and generosity come naturally to Jon and stop short of overextending, because affection and optimism work together in this sextile. Call it comfortable, unforced goodwill, the kind that makes people feel welcome without any performance being needed.
Jupiter conjunction Neptune
about 3.1° at midday
For Jon, growth is likely to be idealistic and compassionate, a matter of causes, beliefs or visions bigger than daily concerns. Jupiter conjunct Neptune supplies the inspiration and leaves them the job of checking a beautiful idea against what can be achieved.
Sun conjunction Mercury
about 3.7° at midday
With the Sun conjunct Mercury, Jon's sense of self and way of thinking are fused, so an opinion can feel like a statement of who they are. They are likely to speak their mind readily, and telling a passing thought apart from their identity is a practice worth keeping up.
Venus trine Uranus
about 4.7° at midday
Closeness does not have to feel confining for Jon, 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.
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.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris. Birth dates and places come from Wikidata; birth times, where StarMap has one, come from Astro-Databank and are shown with their Rodden rating. The readings describe what a placement is traditionally taken to mean. They are written by StarMap for reflection and entertainment, not as statements about the person’s private life. New to charts?
