Moon
The Moon describes your inner life — how you feel things, what soothes you, what you need in order to feel safe. It is the most private part of the chart and often the most accurate.

In Your Chart
Your moon sign explains reactions that surprise even you. Where the Sun is who you are becoming, the Moon is who you already are when nobody is watching.

What The Moon Describes
The Moon is need. It describes what settles a person, what unsettles them, and what they reach for automatically when a situation becomes difficult - the reactions that arrive before any thought about them does.
Where the Sun describes a direction being travelled, the Moon describes the equipment that was issued. It is not chosen and does not develop much over a lifetime; what changes is how well somebody understands it.
In traditional practice the Moon governs the home, memory, the mother, and the body's rhythms. Read plainly, it is the answer to one question: when things are hard, what actually helps you?
Why It Is The Most Private Placement
The Moon describes the part of a person that does not perform for anybody, which is why it is largely invisible from outside and why people frequently recognise their moon sign faster than their sun sign.
It is also the placement most likely to explain why a well-known sun sign description feels only half right. A fire Sun with a water Moon is somebody who moves quickly in public and processes slowly in private, and who is often surprised themselves by how much something affected them.
The Practical Use
This is the most useful placement to know about somebody you are close to, and considerably more informative than comparing two sun signs. It tells you what to do when they are struggling, which is a more practical question than whether two signs are compatible.
A water Moon needs presence rather than solutions. An earth Moon needs the practical problem addressed. A fire Moon needs something to do about it. An air Moon needs to talk it through. Getting this wrong is how well-meaning people comfort each other badly for years.
The Calculation Caveat
The Moon crosses a sign in roughly two and a half days, so it is the fastest-moving placement in a chart and the one most sensitive to birth time after the ascendant. A date alone gets it right most of the time and wrong often enough to matter.
If a moon sign result sits near a sign boundary, the neighbouring sign is genuinely possible when the birth time is uncertain. Unlike the ascendant, though, the Moon is something most people can identify in themselves once they read both candidate descriptions honestly.
