Your Moon sign is the zodiac sign the Moon was passing through when you were born. It reveals your emotional needs, instincts, subconscious patterns and what makes you feel safe. The Moon is the fastest-moving planet in the sky — it changes signs every 2–3 days. That's why the birth date alone is usually enough. In my sessions, the Moon sign is often the placement that explains why someone's Sun sign never quite fit.

Moon Sign FAQ
What does my Moon sign mean?
Your Moon sign describes your emotional nature, instincts, subconscious needs and how you respond to life when no one is watching. It is one of the most personal placements in astrology. In practice: the Moon sign is the placement I check first when someone says 'my horoscope doesn't feel like me.' It usually explains why.
Do I need my birth time for my Moon sign?
Usually not. The Moon stays in one sign for about 2.5 days, so the birth date alone is enough most of the time. If you were born when the Moon was changing signs, the exact time and time zone help.
What is the difference between Sun and Moon signs?
Your Sun sign is your outward identity and conscious will. Your Moon sign is your inner emotional world, your needs and your instinctive reactions. Together they form the core of your personality.
How do Moon signs affect relationships?
Moon sign compatibility reveals emotional rhythm, comfort needs and how two people nurture each other. Compatible Moons feel at home together; clashing Moons may need extra patience.
Can the Moon sign change during the day?
Yes, when the Moon is near the end of one sign it can move into the next within a few hours. That is why adding your birth time and city removes uncertainty.
