What the Moon sign is
The Moon sign is the sign the Moon was in when you were born. Where the Sun is who you are becoming and the Rising sign is how you meet the world, the Moon is the private self: what you need to feel safe, how you react before you think, and what comforts you. The Moon changes sign about every two and a half days, so two people born the same week can have different Moons. (New to this? Atelier Holly has a gentle guide to the Moon sign.)
What the Moon in Aries means
Aries is a fire sign ruled by Mars, the planet of action. The Moon there feels things as a call to do something. It is honest, quick-tempered and quick to forgive, and it would rather face a problem head-on than sit with it. It needs independence, movement and something to aim at, and it can feel caged by too much routine or too much care.
The famous Aries Moons on this page all have that nerve. Marlon Brando was born a couple of hours before a New Moon in Aries, his Sun and Moon side by side, and his instinctive acting made a whole generation start again. Whitney Houston's Aries Moon, with Jupiter in her 1st house, gave her voice its power. Angelina Jolie's sits in her 9th house of travel and causes, with Mars and Jupiter in Aries too. Salvador Dalí's, at the very first degree of Aries, belongs to a painter who never waited for permission.
In love
The Moon in Aries loves with energy and directness. It likes a chase, a spark and a partner who can keep up, and it says what it feels. It needs room to be itself, and it is happiest with someone who is independent too.
At home and in family
An Aries Moon home is lively rather than quiet: a place to come back to between adventures, with space to move. As a parent it is energetic, encouraging and protective, and it wants its children to be brave.
The harder side
The same speed can turn into impatience, a short temper or a habit of acting before feeling things through. An Aries Moon may push past its softer emotions, or treat needing help as a weakness. The lesson of this Moon is that slowing down is sometimes the brave thing.
How it differs from its neighbours
A Moon in Pisces, the sign before, takes in every feeling around it, where Aries reacts to its own. A Moon in Taurus, the sign after, takes its time, where Aries wants it now. And its opposite, the Moon in Libra, looks for peace and balance with others, where Aries looks for freedom to act.
Find your Moon sign
Your Moon sign needs your birth date and place, and ideally your birth time, because the Moon moves about 13 degrees a day. If you don't know the time, the chart is set for noon, and it will still give your Moon sign unless the Moon changed sign that day. Find your Moon sign.
Questions
Is the Moon in Aries rare?
No. The Moon passes through every sign once a month, so about one person in twelve has an Aries Moon.
Is an Aries Moon angry?
Not more than anyone else, but it shows anger quickly and openly, and then lets it go. It rarely holds a grudge.
What does an Aries Moon need to feel safe?
Freedom to act, a challenge and people who are straight with it. Exercise, a project or a fresh start will settle it faster than talk.
