Ronald Koeman’s birth chart
Born 21 March 1963, in Zaandam, Netherlands. StarMap has no verified birth time yet.
Sun in Pisces or Aries · Moon in Capricorn or Aquarius
Ronald Koeman’s zodiac sign and chart, in brief
21 March 1963 was a Thursday: the day Ronald Koeman was born in Zaandam, Netherlands. The Sun moved from Pisces into Aries at about 09:20 local time that day, so the zodiac sign depends on the birth time: Pisces for a birth before then, Aries after. The Moon was in Capricorn until about 02:20 and in Aquarius afterwards, so the Moon sign turns on the birth time. Ronald turns 63 in 2026. StarMap has not verified a birth time yet, so the chart is cast for midday on that date and has no houses.
By element the count is three water, two earth, two air and one fire, leaving out the Sun and the Moon, whose signs depend on the birth time. By modality the count is four fixed, four mutable and no cardinal. The tightest aspect is Venus conjunction Saturn, about 0.8° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Uranus, Neptune and Pluto were retrograde. The Moon was a waning crescent.
StarMap's dataset holds 17 other people born on 21 March, among them Ronaldinho, Gary Oldman and Antoine Griezmann.

Ronald Koeman’s Sun, Moon and rising sign
Sun sign
Pisces or Aries
Pisces until about 09:20, then Aries (local time). Which one depends on a birth time StarMap does not have.
Born before about 09:20: Sun in Pisces
A Pisces Sun feels it all. Imagination, empathy and a porous sense of where the self ends and others begin tend to make Ronald Koeman the kind of person people confide in. This placement needs boundaries as much as it needs the sea.
Born after about 09:20: Sun in Aries
An Aries Sun starts things. For Ronald that points to energy that is direct and impatient with delay, and to feeling most like themselves when there is something to go first at. The work of this placement is finishing what the spark began.
Moon sign
Capricorn or Aquarius
Capricorn until about 02:20, then Aquarius (local time). Which one depends on a birth time StarMap does not have.
Born before about 02:20: Moon in Capricorn
A Capricorn Moon feels responsibly. With it, Ronald may hold themselves together for other people, and can be hard on themselves when they cannot. This Moon tends to be restored by accomplishment, by structure, and by the rare person allowed to see them tired.
Born after about 02:20: Moon in Aquarius
An Aquarius Moon feels from a step back. Ronald is likely to understand an emotion better than they inhabit it, and to need space and ideas to process. For this Moon, friends are family and freedom is security.
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 Zaandam, Netherlands, at each hour of the day.
Ronald Koeman’s rising sign, by birth time
StarMap has not verified a birth time for Ronald 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 21 March 1963, computed for Zaandam, Netherlands.

The chart wheel
Drawn for midday on 21 March 1963, with only the aspects that held all day. The Moon may stand up to eight degrees either side of where it is drawn. The Sun is drawn at its midday place; it moved from Pisces into Aries at about 09:20, so its sign depends on the birth time. How to read a chart wheel

Ronald Koeman’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Ronald Koeman’s private life.
Sun in Pisces or Aries
Pisces until about 09:20, then Aries
purpose and vitality
Born before about 09:20: Sun in Pisces
The Sun in Pisces finds purpose in imagination, compassion and things that cannot quite be measured, and Ronald Koeman'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.
Born after about 09:20: Sun in Aries
With the Sun in Aries, Ronald's sense of purpose tends to come alive when there is a clear start line. They probably feel most like themselves pushing into something new, though that energy can burn hot and fade before the finish. The typical pattern is a project launched with excitement, then handed off once the routine sets in.
Moon in Capricorn or Aquarius
Capricorn until about 02:20, then Aquarius
needs and habits
Born before about 02:20: Moon in Capricorn
With the Moon in Capricorn, Ronald's comfort probably comes from accomplishing something concrete each day, and an unproductive day can leave them oddly unsettled even on holiday. Harder feelings tend to be kept for when they are alone. Before rest is allowed there is usually one more thing to tidy, organise or finish.
Born after about 02:20: Moon in Aquarius
An Aquarius Moon processes daily feelings by stepping back and thinking them through rather than sitting inside them, and Ronald is likely to need a degree of independence built into any close relationship. The temptation is to analyse a feeling instead of simply having it. Even after a good day with people, this Moon needs time alone to recover.
Mercury in Pisces thinks in images and impressions more than straight lines, and Ronald 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. Ronald 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 Leo acts with confidence and wants the effort to be visible, and for Ronald 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 Pisces
26° Pisces 42' at midday
growth and excess
For Ronald, Jupiter in Pisces means finding growth in compassion, imagination and a willingness to trust things that cannot be fully explained. The overreach is an idealism about people or situations that the facts do not quite support. Others lean on this generosity of spirit more than they let on.
With Saturn in Aquarius, Ronald's discipline probably gathers around belonging to a group on their own terms; it is the placement of the one-time outsider. The doubt means holding back the stranger ideas until there is no risk of mockery. The outsider often ends up as a trusted voice in exactly the kind of community that once seemed unlikely to accept them.
Uranus in Virgo
2° Virgo 08' at midday ℞
freedom, generational
Uranus takes about seven years to cross a sign, so in Ronald's chart Uranus in Virgo describes an age group as much as a single person. It is a generation that changes how work and daily routine are done, through new methods and new technology. In one person it can be an instinct to question inherited routines.
Neptune in Scorpio
15° Scorpio 21' at midday ℞
imagination, generational
Neptune in Scorpio marks a long season that Ronald shares with many people of a similar age. Its imagination is drawn to the hidden, the taboo and the transformative, with a wider cultural fascination for secrets and endings. In an individual that can be a pull towards mystery for its own sake.
Pluto in Virgo
10° Virgo 22' at midday ℞
power, generational
Pluto in Virgo is shared by Ronald 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 Ronald Koeman’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.
Venus conjunction Saturn
about 0.8° at midday
Venus conjunct Saturn describes a serious, committed way of loving, and Ronald Koeman is likely to treat a relationship as something to build, not simply to enjoy. Loyalty comes with it. So does the harder task of trusting that affection can be deserved before it has been worked for.
Sun conjunction Jupiter
about 3.4° at midday
Ronald's identity carries a natural optimism and a generous sense of scale, so they tend to think bigger than the room requires. Confidence comes easily with the Sun conjunct Jupiter, and the discipline worth building is matching that optimism with follow-through.
Saturn square Neptune
about 3.7° at midday
Practical sense and idealism can pull against each other in this square, and for Ronald that may mean either an uninspired routine or a dream with no realistic plan behind it. The way through is to build the structure and protect the dream at the same time, without sacrificing one for the other.
Venus square Neptune
about 4.5° at midday
Under Venus square Neptune, affection can blur into an idealised picture of love, and disappointment follows when a real person or relationship falls short of the dream. Ronald's task is to love what is there, which tends to prove more durable than loving the fantasy.
Sun trine Mars
about 5.4° at midday
Confidence and drive move in the same direction for Ronald, so they are likely to act on their goals with very little inner resistance. The energy of a Sun-Mars trine is uncomplicated, and other people notice it and often want to be near it.
Mercury conjunction Jupiter
about 5.6° at midday
Ronald's thinking is likely to be expansive and enthusiastic, connecting ideas across subjects other people keep separate. It makes for lively conversation, and the habit worth adding is checking the details behind a big idea before committing to it fully.
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.
