Moon
The Moon is what somebody needs in order to be alright: the emotional baseline, what soothes and what unsettles, and the response that arrives before any decision to respond.

Where It Sits In Your Chart
The Moon is the private layer, and almost nobody sees it except the people who live with you. It moves fast enough that a birth hour matters — roughly one birth in three falls on a day it changed sign.

What The Moon Is Assigned
The Moon is given emotional need: what somebody requires in order to feel settled, what soothes and what unsettles, and how they respond before composing a response.
It is the private layer. Where the Sun describes what somebody is driving at and the ascendant how they arrive, the Moon describes what is happening underneath both.
It is frequently the placement that feels uncomfortably accurate on first reading, precisely because it describes the part that is not performed.
The Fastest Body In The Chart
The Moon crosses a sign in roughly two and a half days and completes the zodiac in 27.3 days, which makes it the quickest-moving placement after the ascendant.
That speed is why it separates people born in the same week, and why a birth hour matters for it more than for any other planet.
Roughly one birth in three falls on a day the Moon changed sign, in which case the hour decides between two adjacent possibilities.
Why It Is Hard To Compute
The Moon's motion is genuinely difficult. Its orbit is perturbed by the Sun, its speed varies across the month, and a simple average produces errors large enough to put it in the wrong sign near a boundary.
Where The Moon Stood deals with that by testing for a crossing on your date and, if one occurred, reporting the minute it happened — instead of handing back the noon figure as though nothing were in doubt.
That behaviour is the point of the tool. The answer matters less than knowing whether the answer is certain.
Natal Versus Transiting
Two different things share the name and the confusion is constant. Your natal Moon is where the Moon stood when you were born and it belongs to you permanently.
Tonight's Moon is transiting — where it is now — and it applies to everybody equally. The phase reported on our lunar calendar is this one.
The natal Moon is the significant placement for self-understanding. The transiting one is weather.
Rulership And The Luminaries
The Moon rules Cancer, and like the Sun it was assigned a single sign rather than the pair given to every traditional planet.
The two are treated as the luminaries — a category apart from the planets, carrying more weight in a reading than anything else in the chart.
That weighting survives in modern practice, and it is why Sun, Moon and ascendant are conventionally learned first.
Questions About The Moon
How do I find my Moon sign? Put your birth date into Where The Moon Stood, with the hour if you have it. The tool says outright whether the hour changes the answer in your case.
Can I know it without a birth time? About two times in three, yes — the Moon did not change sign that day and the answer is certain. The remaining third needs an hour.
Why does my Moon sign feel more accurate than my Sun? Because it describes the layer you do not perform, which is the one people recognise most sharply in themselves.
