Moon Sign Calculator

Uncover your emotional blueprint — the sign that governs your feelings, instincts, and deepest needs.

Birth time is optional for Moon sign but improves accuracy. Without it, the Moon may be on a sign boundary.

Moon & Emotions

The Moon governs your emotional reactions, habits, and subconscious patterns. It reveals how you nurture yourself and seek comfort.

Birth Time Accuracy

The Moon changes signs roughly every 2.5 days. If your birth time is unknown, you might be near a sign boundary — we'll let you know.

Your Inner Self

While the Sun represents your public persona, the Moon reflects your private emotional world — the part of you only close ones see.

What Is a Moon Sign?

Your Moon sign is the zodiac sign the Moon occupied at the moment of your birth. It governs your emotional core — how you feel, react, and process your inner world.

Does Birth Time Matter for Moon Sign?

The Moon moves about 12° per day, changing signs every ~2.5 days. If you were born near a sign change, even a few hours' difference can shift your Moon sign.

Moon Sign vs Sun Sign

Your Sun sign and Moon sign work together, but they answer fundamentally different questions. The Sun asks: What am I building? What do I want to be known for? What drives my will? It is your conscious identity — the part you develop deliberately over a lifetime. A Capricorn Sun pursues mastery. A Leo Sun pursues recognition. You choose to embody your Sun. The Moon asks: What do I need? What calms me down? What do I reach for when the mask slips? It is your emotional default — the part that operates on instinct, not intention. A Capricorn Moon needs structure. A Leo Moon needs to feel special. You do not choose your Moon; it chooses you. Here is where it gets interesting. When your Sun and Moon signs align in element (both fire, both earth), your inner world and outer ambitions pull in the same direction. Life feels coherent. When they conflict — a fiery Aries Sun with a cautious Cancer Moon, for example — you carry an internal tension that can be confusing but also deeply creative. The Sun pushes forward; the Moon pulls back. Learning to honor both is the work of a lifetime. Sun-sign astrology dominates pop culture because it is easy to calculate — you only need a birthday. Moon sign astrology requires more precision but delivers a far more intimate portrait. If your Sun sign horoscope never feels quite right, your Moon sign reading often fills the gap.
