The Moon in Astrology: Emotions, Needs and Instinct
The Moon describes your emotional life: what makes you feel safe, how you react before you think and what you need from home and the people closest to you. It moves through a sign in about two and a half days, so your Moon sign is far more individual than your Sun sign.

What the Moon describes in a birth chart
Where the Sun is who you are becoming, the Moon is who you already are when nobody is watching. It governs habits, moods, memory and the body's needs: sleep, food, comfort. People often recognise themselves in their Moon sign faster than in their Sun sign because it describes reactions they have every day.
The Moon is also read for the experience of being cared for, often the mother or main carer, and for the way you care for others in turn. A Moon in a sign that suits it tends to settle easily; a Moon in a sign where it has to work harder, or under hard aspects, describes needs that are harder to name and to ask for.
The Moon in the twelve signs
Because the Moon changes sign every two to three days, a birth time matters. Born on a day the Moon changed sign, your Moon could be in either one, and the calculator will tell you when that applies. Fire Moons need action and honesty, earth Moons need stability and touch, air Moons need talk and space, and water Moons need closeness and time to feel things through.
The Moon in the houses
The Moon's house shows where you look for emotional security. A fourth-house Moon is at home in home; a tenth-house Moon often feels safest when publicly useful; an eleventh-house Moon needs friends and a group to belong to.
The Moon's aspects
Venus aspects soften the Moon and make affection easier to show. Saturn aspects make feelings more guarded and self-reliant. Mars aspects speed up reactions. Pluto aspects deepen everything and make trust a central issue.
The Moon in relationships
The Moon is the first placement most astrologers compare between two charts, because it shows how two people live together day to day. Two Moons in compatible elements tend to feel easy; a Moon square another person's Moon can mean very different ideas of comfort.
The Moon in transit
The transiting Moon touches every point in your chart once a month, so it times moods and small events rather than big chapters. New and full moons that fall on your natal planets are worth watching. The Moon's sign each day is the base of the daily horoscope.
Common questions
Do I need my birth time for my Moon sign?
Usually not, but it helps. On days the Moon changed sign, the time decides which sign it was in.
What is the Moon sign for?
Reading your emotional needs and how you react. It is also the placement most used to compare two people living together.
