Birth time unknown

Birth date sourced. Birth time unknown.The Moon remained in Virgo throughout that civil day. Everything below uses only what the complete civil day settles.

The day, read honestly

Five of the ten placements whose signs are settled stand in Libra — the Sun, Mercury, Jupiter, Saturn and Pluto. The placements whose signs could change with an unknown hour are not counted. A cluster that size becomes the section the rest of the chart plays around.

Positions at 12:00 civil time in Saginaw—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

The Sun sits at 3.5° Libra — the first decan, 0°–10°, which the tradition sub-rules by Venus. Degrees matter more than the sign label here: two people born a fortnight apart share Libra and share almost nothing else about where the Sun actually stood.

The angles that hold

The tightest geometry in the chart puts Venus at right angles from Mars, 0.6° off exact. The old texts treat a square as the aspect you feel earliest and thank latest: obstruction first, competence afterwards. Behind it, Neptune sextile Pluto at 1.2°, and Mars sextile Jupiter at 1.6° — both still well inside the orbs this site uses. Every angle named here holds for the whole of that day at the birthplace, so an unknown hour cannot take it away.

The classical map

The dignity table, which predates the outer planets and only ever spoke for seven, marks three placements here. The Sun in Libra at 3.5° is in fall — the tradition’s uphill placement, strength earned rather than given; Venus in Scorpio at 15.9° is in detriment — the planet opposite its home, working against the grain; Saturn in Libra at 11.7° is in exaltation — the tradition’s honoured-guest placement, working at its best. None of these labels is a verdict on a person; they describe how a function is situated, nothing more.

The shape of the whole

Among the 10 placements whose signs hold for the whole day, the elements divide 5 air, 2 water, 2 fire, 1 earth; by modality, 5 cardinal, 3 fixed, 2 mutable. An air emphasis is read as distance for the sake of clarity: the idea gets examined before it gets adopted. Every body was moving forward that day — no apparent reversals anywhere in the chart.

The Moon, and how far it can move

The Moon stayed in Virgo for the whole of that day at the birthplace, covering 12.8° between midnight and midnight. The sign survives the missing hour; the degree does not, and is given as a reference rather than a fact. At the noon reference it stands at 15.9°.
