Born: January 9, 1982, 7:00 PM local time, Reading, England. Source: Astro-Databank, Rodden rating C.
A C rating means sources disagree on the exact birth time and none is confirmed. The date itself isn't in question, so the planets' signs and the aspects between them hold up. The rising sign, the Midheaven and the houses below are conditional on the recorded 7:00 PM time, so this read treats them carefully and keeps them brief. Open Kate Middleton's chart on Astrolas to follow along.
One grouping holds regardless of the exact minute she was born. Three of the ten planets sit together in jLibra: Mars, Saturn and Pluto. Sign placements like this don't shift much within a single day, so this part of the chart is solid ground. If the recorded time holds, all three also share the 3rd house, the part of a chart the Astrolas library ties to communication and the people nearby.
A second pairing sits close behind it: Mercury and Venus, both in xAquarius and in exact conjunction, an aspect the library does have a reading for.
Mars, Saturn and Pluto in Libra
Mars sits at 10ยฐ28' Libra, Saturn at 21ยฐ50' Libra, and Pluto at 26ยฐ49' Libra.
The library's Libra Mars puts energy into relationships rather than solo pushes, seeking balance in both love and work, with a dislike of rudeness or unfairness strong enough to provoke a real reaction. Saturn in Libra sharpens judgment and builds a strong sense of fairness, suiting work as a mediator or in diplomacy, law or the arts, and the library notes a tendency to marry later, to someone more mature. Pluto in Libra is generational, shared by everyone born between 1971 and 1984, a cohort that came of age alongside the end of the Vietnam War and the Watergate scandal; on a personal level it reads as a drive toward cooperative, equal relationships, with real strain possible if either side gets too rigid about fairness.
If the recorded time holds, all three sit in the 3rd house. The library reads Mars here as outspoken and quick to react, with a competitive streak in conversation; Saturn here as cautious, methodical and responsible, leaning on verified information rather than instinct, though prone to delay while waiting for certainty; and Pluto here as a mind that digs into information down to its roots, speaking rarely but with real weight once it does.
Kate studied History of Art at the University of St Andrews, graduating in 2005, the same year William graduated with a geography degree, and has built a public role partly around careful, considered communication rather than frequent public statements.
Mercury conjunct Venus in Aquarius
Mercury sits at 6ยฐ14' Aquarius and Venus at 7ยฐ13' Aquarius, retrograde, a conjunction with an orb of 0ยฐ59'.
The library's Aquarius Mercury is original and a little ahead of its time, drawn to psychology and human motivation and sometimes seen as eccentric for ideas that later prove right. Venus in Aquarius loves with room to breathe, valuing friendship and personal freedom as much as romance, and reacts badly to jealousy or being boxed in. The conjunction itself, in the library's reading, is a charming, witty communicator who can talk to anyone, with a literary streak and a gift for smoothing over conflict.
If the recorded time holds, both sit in the 6th house of daily work, where the library adds a liking for a pleasant workplace, a gentle and cooperative manner with colleagues, and an interest in pets as a source of calm.
Kate wrote her undergraduate thesis on 19th-century photography and has been patron of the National Portrait Gallery since 2012 and of the Royal Photographic Society since 2019. She has also acted as her family's de facto photographer for years, regularly releasing her own portraits of her children.
Jupiter in Scorpio and Uranus in Sagittarius, in the 4th house
Jupiter sits at 7ยฐ16' kScorpio and Uranus at 3ยฐ08' lSagittarius. If the recorded time holds, both fall in the 4th house of home and family.
The library's Scorpio Jupiter brings willpower and a sharp instinct for turning opportunity into real gain, often through sustained effort rather than luck alone. Uranus in Sagittarius is generational, marking a cohort oriented toward higher education, travel and new ideas about belief, rather than anything personal to Kate on its own.
In the 4th house, the library reads Jupiter as warmth toward family and a wish for a spacious, comfortable home, sometimes stretching a budget to get there, with real support or an unexpected boost sometimes coming from relatives. It reads Uranus here as a family that doesn't fit a traditional mold, with one or both parents different from the norm in career or lifestyle, and a need for room to form an identity apart from the family's usual pattern.
Kate's parents, Michael and Carole Middleton, built Party Pieces, a mail-order party supplies company, into a national business from scratch, a very different background from the family she married into. She has stayed close to her parents and her sister Pippa throughout her public life.
Sun in Capricorn, Moon in Cancer
The Sun sits at 19ยฐ12' vCapricorn and the Moon at 18ยฐ42' fCancer, in opposition with an orb of 0ยฐ31', the tightest aspect in the whole chart. The library has no text yet for this exact pairing, so it stands only as a fact: identity and feeling pulling toward opposite ends of the same axis.
The library's Capricorn Sun is disciplined and ambitious, matures early, and can come across as reserved or guarded with its emotions; in love it wants a steady, trustworthy partner over spontaneity. The Cancer Moon, in the sign the library calls its natural home, is deeply sensitive, loyal and protective, with a strong memory and a wish for a secure home base.
If the recorded time holds, the Sun sits in the 5th house of creativity and children, which the library ties to playful self-expression and, for people without children of their own, "spiritual children" in the form of creative projects. The Moon would sit in the 11th house of groups, which the library ties to close friendships that feel like family and a comfort in leadership roles within organizations.
Kate has three children, Prince George, Princess Charlotte and Prince Louis, and has built her public work largely around them: the Centre for Early Childhood, launched through the Royal Foundation in 2021, focuses on the first five years of a child's life. She has also kept long-running ties to groups like the Scouts, where she volunteered as a cub leader in Anglesey starting in 2012, years before becoming the organization's joint president in 2020.
Neptune in Sagittarius, in the 5th house
Neptune sits at 25ยฐ28' Sagittarius. If the recorded time holds, it falls in the 5th house of creativity and children, alongside the Sun.
Neptune in Sagittarius by sign is generational, tied by the library to a search for meaning and a pull toward other cultures and belief systems. In the 5th house, the library describes a rare, richly imaginative creative energy, often expressed through art, photography, music or dance, along with a tendency to see a firstborn child as unusually creative too.
Kate's own creative outlet has stayed close to the camera rather than the stage, photography learned partly through her art history studies, that she now uses to document her own children.
If the recorded time holds: Leo rising
The Ascendant would sit at 20ยฐ00' Leo. The Astrolas library has no entry yet for this rising sign on its own, and given the uncertainty around Kate's birth time, this read doesn't lean on it for meaning. The sign placements above, Libra, Aquarius, Scorpio, Sagittarius, Capricorn and Cancer, stay solid regardless of the exact minute she arrived.
What the chart adds up to
The chart doesn't explain a public role built largely by marriage rather than birth. What it shows, with reasonable confidence, is a Libra group built for careful diplomacy and a Mercury-Venus pair built for easy, friendly communication, both suited to a life spent representing other people as much as herself.
Open Kate Middleton's chart on Astrolas, find the Libra group on the wheel, then compare it with a chart you know.
Questions people ask
Is Kate Middleton a Leo rising?
Possibly, based on the recorded 7:00 PM birth time, but the C rating means that time isn't confirmed, so any rising sign here is tentative.
What are Kate Middleton's Sun and Moon signs?
Sun in Capricorn at 19ยฐ12', Moon in Cancer at 18ยฐ42'. The two are in opposition, just 0ยฐ31' apart, the tightest aspect in her chart.
What is the strongest feature of her chart?
Three planets together in Libra: Mars, Saturn and Pluto. Mercury and Venus are also conjunct in Aquarius. Both groupings hold regardless of the exact birth time, since only their house placement depends on it.
