Birth time unknown

Birth date sourced. Birth time unknown.Moon sign undetermined. The Moon crossed from Pisces into Aries during that day. Everything below uses only what the complete civil day settles.

The day, read honestly

Four of the nine placements whose signs are settled stand in Taurus — the Sun, Mercury, Venus and Mars. 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 Neuwaldegg—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

At noon on that date the Sun stood at 6.4° Taurus, inside the first decan (0°–10°), whose traditional sub-ruler is Venus. The decan is the older, finer division — it is what the sign looks like once you stop rounding it to thirty degrees.

Closer to the ground

Closer in, Mercury stands at 7.7° Taurus; Venus stands at 13.7° Taurus; Mars stands at 20.5° Taurus. The tradition reads thought with its feet on the ground from Mercury, attraction that grows by reliability from Venus, effort banked steadily until it tells from Mars.

The angles that hold

The tightest geometry in the chart puts Venus at right angles from Saturn, 0.2° off exact. Nothing in a square flows; everything in it works. The old texts kept squares for the charts they respected. Behind it, Mercury trine Jupiter at 0.5°, and the Sun conjunction Mercury at 1.4° — 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.

What the angles build

The Moon makes no major aspect that survives the day; the old reading gives such a planet autonomy — it acts alone, sometimes loudly.

The classical map

The oldest layer of the scheme — seven planets, four conditions — flags four placements in this chart. Venus in Taurus at 13.7° is in domicile — the planet in its own sign, running on home rules; Mars in Taurus at 20.5° is in detriment — the planet opposite its home, working against the grain; Jupiter in Capricorn at 8.3° is in fall — the tradition’s uphill placement, strength earned rather than given; Saturn in Leo at 13.6° is in detriment. The table describes circumstance rather than quality — a planet in detriment is inconvenienced, not diminished.

The shape of the whole

Of the 9 placements whose signs hold for the whole day: 5 in earth, 3 in air, 1 in fire by element, 5 fixed, 2 cardinal, 2 mutable by modality. An earth emphasis reads as trust in the tangible: the plan matters less than whether the thing stands up. No settled placement falls in water — an absence the tradition treats as information, not as a defect. Venus, Jupiter and Uranus were retrograde — apparent backward motion from where the Earth sits, which the tradition reads as a function turned inward before it is turned out.

The Moon is genuinely open

The Moon crossed from Pisces into Aries during that day at the birthplace, travelling 12.9° between one midnight and the next. Without a recorded hour there is no honest way to say which side it was on, so this reading does not say. The Moon sign is a real question here, not a rounding error, and it needs a birth time nobody has published.
