Frequently Asked Questions
What is a Moon sign?+
Your Moon sign is the zodiac sign the Moon was in at the exact moment you were born. While your Sun sign represents your conscious identity and ego, your Moon sign governs your emotions, instincts, subconscious patterns, and what you need to feel safe. It's often called your "inner self" — the part of you that comes out in private, in moments of stress, or with the people you trust most.
How is Moon sign calculated?+
Your Moon sign is calculated using the precise astronomical position of the Moon at your birth date and time. The Moon moves through all 12 zodiac signs roughly every 28 days, spending about 2.5 days in each sign. This is why even people born on the same day can have different Moon signs — a few hours can make the difference. Our calculator uses NASA JPL precision ephemeris data for accurate results.
Why is birth time important for Moon sign?+
Because the Moon changes signs approximately every 2.5 days, knowing your birth time helps ensure accuracy — especially if you were born on a day when the Moon switched signs. Without a birth time, we use noon as a default, which is accurate for most people. However, if you were born near a Moon sign boundary, your actual Moon sign could differ. Birth time is also needed to determine which house your Moon falls in, which adds important context about where your emotional energy is directed.
Moon Sign Meanings for All 12 Signs
