My Birth Chart

Your date, your time, your place — and the chart appears: the Ascendant, the twelve houses, the aspects, to the arc minute. Every point opens onto a summary.

The hard aspects are warm, the soft ones are cool. A solid line is tight, a dotted line is wide.

    What this page does not do

    It crosses nothing: every box is read alone, while a chart is read all of a piece.

    It does not read the cycles: where you stand today does not show in a birth chart displayed as it is.

    And it does not know who you are. A dictionary never does.

    The real questions

    What you can check for yourself.

    How precise is it, and is it really the same calculation as your readings?

    It is the same reference engine, checked automatically against the documents I sell. The gap with a document never exceeds one arc minute. On Neptune, which moves very slowly, the last minute shown can differ by one unit in roughly one chart out of six: two different astronomical models sometimes land on either side of a rounding. The sign, the house and the aspects are identical.

    Why does the birth time change so much?

    The Earth turns: the Ascendant moves about one degree every four minutes. Without the time there is no Ascendant, no Midheaven and no houses — that is, neither the “how it comes through” nor the “in which area of life”. The planets in signs and their aspects stay accurate. If you do not know your time, tick the box: the page tells you exactly what remains reliable, and what it refuses to invent.

    What is a house?

    Signs give the color of an energy; houses give the area of life where it plays out — work, partnership, home, money, friendship. The same Venus in Taurus does not tell the same story in house II as in house X. That is why the time matters, and why an isolated placement means almost nothing.

    Why do you say this is not enough?

    Because it is true, and better said before you find out. This page is a dictionary: it gives one word per box. It cannot do otherwise, it does not know who you are. A reading crosses everything — the planets with one another, the houses, the aspects, the cycles under way — and it is that crossing which produces a sentence that is true about you, rather than a definition valid for one twelfth of humanity.
