John Calvin Coolidge Sr. birth chart is shown with zodiac signs and aspects. Because the birth time is unknown, Arcadia does not use houses, Rising sign, or angular dominants as the main basis of interpretation.
John Calvin Coolidge Sr.'s chart rests first on the stable factors: Sun in Aries and Moon in Capricorn. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Mars square Jupiter (orb 1.4°) gives a central dynamic in this reading. The orb is very tight; this describes a stable character pattern more than a passing reaction.
In plain terms, this aspect creates tension between action, excess, impatience, competition, and risk-taking.
The birth time is not known with certainty, so the Rising sign and houses are less reliable. Signs and exact aspects give the safer reading base.

Signs Venus in Pisces · Mars in Capricorn · Sun in Aries
Aspects Sun square Mars (orb 3.4°)
This section gives a concrete reading thread. It highlights the most visible signatures, then the tabs keep each placement separate instead of mixing everything together.
Important: Unknown birth time: the Rising sign, houses, and angular dominants are too time-sensitive to anchor the interpretation. The Moon remains useful, but its exact aspects can shift during the day: tight non-Moon aspects are more reliable when they exist.
Start here: a short reading that shows what hooks, what helps, what pushes back, and where it becomes concrete.
Sun in Aries · Moon in Capricorn
First hook: this is where the chart often becomes recognizable in real life. Sun in Aries: identity and direction move through initiative, speed, confrontation, and direct action; Moon in Capricorn: emotional safety looks for structure, ambition, responsibility, and long construction. Because the birth time is missing, reliable aspects should carry the next step before houses or angles.
Dominants unavailable without reliable birth time
Angular dominants depend on birth time. Without a reliable hour, do not use them as primary evidence.
Harmonious circuit: Saturn, Jupiter, and Mercury
This is the easiest door into the chart: it shows what tends to cooperate naturally.
This pattern describes what comes more easily. Houses are not used here: unknown time. It connects Saturn (responsibility, limits, effort, and patience), Jupiter (growth, faith, luck, and confidence in the future), and Mercury (thinking, speech, and decisions).
This is the clearest cooperation pattern in the chart: Jupiter sextile Saturn (orb 0.8°) and Mercury sextile Saturn (orb 3.5°). It shows where functions support each other, recover, or come naturally when used together. Because several planets are connected, the full pattern matters more than one isolated aspect.
Tension circuit: Mars, Jupiter, and Sun
This is the pressure line to read first: it shows where tension repeats in concrete situations.
This pattern shows where pressure builds fastest. Houses are not used here: unknown time. It connects Mars (action, anger, desire, and courage), Jupiter (growth, faith, luck, and confidence in the future), and Sun (identity, confidence, and direction).
This is the clearest friction pattern in the chart: Mars square Jupiter (orb 1.4°) and Sun square Mars (orb 3.4°). It shows where pressure, contradiction, or repeated effort concentrates. Because several planets are connected, the full pattern matters more than one isolated aspect.
Houses unavailable without reliable birth time
Houses describe domains of existence, but they depend on birth time. Without a reliable hour, signs and aspects should carry the reading.

Without a reliable birth time, the Sun, Moon, and exact aspects become the reliable base. The Rising sign, houses, and angular dominants need a reliable birth time.
The Moon can change signs during a day. Near a lunar sign change, the Moon sign remains a hypothesis.
Without a reliable hour, exact aspects and reliable repetitions can strongly nuance the starting reading.
Sun in Aries remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Aries style: initiative, speed, confrontation, and direct action.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Aries style (initiative, speed, confrontation, and direct action). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Sun square Mars (orb 3.4°). Aspect effect: creates visible tension between ego, father image, and action: will can feel attacked, blocked, or forced to prove strength, sometimes through a weak, absent, inhibiting, or castrating father image.
Sun conjunct Uranus (orb 4.2°) brings the two planets out together. The orb is moderate; it stays secondary beside tighter signatures.
Here, both planets use the same Aries style (initiative, speed, confrontation, and direct action). Sun in Aries brings identity, ego, father figure, visibility, and direction; Uranus in Aries brings disruption, independence, and change.
Concrete effect: this aspect ties identity to independence, rupture, and the need not to fit the frame.
Sun conjunct Jupiter (orb 4.8°) brings the two planets out together. The orb is moderate; it stays secondary beside tighter signatures.
Here, both planets use the same Aries style (initiative, speed, confrontation, and direct action). Sun in Aries brings identity, ego, father figure, visibility, and direction; Jupiter in Aries brings personal fulfillment, confidence, encouragement, and broader horizons.
Concrete effect: this aspect brings identity, ego, confidence, personal fulfillment, and the need to widen life together.
Sun square Mars (orb 3.4°) creates concrete friction between the two planets. The orb is tight enough to count in the main reading.
Here, Sun in Aries brings identity, ego, father figure, visibility, and direction with Aries style (initiative, speed, confrontation, and direct action); Mars in Capricorn brings action, courage, competition, and effort with Capricorn style (structure, ambition, responsibility, and long construction).
Concrete friction: this aspect creates visible tension between ego, father image, and action: will can feel attacked, blocked, or forced to prove strength, sometimes through a weak, absent, inhibiting, or castrating father image.
Moon in Capricorn remains a useful base without a birth time. The Moon sign is often usable, but near a Moon sign change it remains a hypothesis; the Moon describes personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm, with Capricorn style: structure, ambition, responsibility, and long construction.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Capricorn style (structure, ambition, responsibility, and long construction). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Moon square Mercury (orb 1.3°). Aspect effect: creates tension between personal dream and intellect: thought can cut the play instinct, or the dream can overflow rational wording.
Time-sensitive Moon aspect: Moon square Mercury (orb 1.3°). Because the birth time is unknown, the Moon's exact degree can shift during the day. This interpretation stays provisional and gains weight only if the aspect remains tight across the possible birth window or repeats another clear signature.
Here, Moon in Capricorn brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Capricorn style (structure, ambition, responsibility, and long construction); Mercury in Aries brings intellect, language, thought, and technique with Aries style (initiative, speed, confrontation, and direct action).
Concrete friction: this aspect creates tension between personal dream and intellect: thought can cut the play instinct, or the dream can overflow rational wording.
Time-sensitive Moon aspect: Moon square Pluto (orb 2.1°). Because the birth time is unknown, the Moon's exact degree can shift during the day. This interpretation stays provisional and gains weight only if the aspect remains tight across the possible birth window or repeats another clear signature.
Here, Moon in Capricorn brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Capricorn style (structure, ambition, responsibility, and long construction); Pluto in Aries brings crisis, power, survival, and regeneration with Aries style (initiative, speed, confrontation, and direct action).
Concrete friction: this aspect creates tension between personal dream, childhood, mother image, control, and fear: protection can become suspicion, grip, or overreaction.
The Rising sign cannot be determined if the time is not known.
