What your Moon sign means
Your Moon sign describes your emotional nature: how you feel, what makes you feel safe, and how you instinctively react. While your Sun sign is who you are becoming, your Moon is who you are underneath — your needs, your moods, and the way you nurture and want to be nurtured. Because the Moon moves quickly through the zodiac (changing signs every 2–3 days), an accurate birth time and date are important for a precise result.
Frequently asked questions
What is a Moon sign?
Your Moon sign is the zodiac sign the Moon was in when you were born. It governs your emotional world, instincts, and what you need to feel secure — often considered the most intimate part of your chart.
Do I need my birth time for my Moon sign?
Ideally yes. The Moon changes signs every 2–3 days, so if you were born on a day the Moon switched signs, the time decides which one is yours. If you’re unsure, an approximate time still gets you close.
Why is my Moon sign different from my Sun sign?
They describe different things. Your Sun sign is your core identity; your Moon sign is your emotional inner life. It’s completely normal — and common — for them to be in different signs.
