Moon Sign Calculator
Your Moon sign is the sign the Moon was in when you were born, read in astrology as your emotional side and what makes you feel secure. The Moon changes sign about every two and a half days. A birth time pins it down; without one, you still get an answer, and if the Moon changed signs that day you will see both possibilities.
The 12 Moon signs
Aries MoonFeels it fast, says it fast, then lets it goA Moon in Aries means emotions arrive quickly and want somewhere to go. When you're frustrated, sitting still with it feels worse than doing something: a hard run, scrubbing the bathtub, a text you might have edited with five more minutes. Anger and hurt flare, then burn down faster than the people around you expect. You feel safest when you're allowed to act on a feeling instead of waiting for permission to have it.
Taurus MoonCalms down with warm bread and a familiar blanketVenus rules Taurus, and the Moon here finds security through the senses and through things that stay put. Under stress you might make the same chili you've made a hundred times, pull on a sweatshirt from college, or rewatch a sitcom you can quote line by line. Feelings move slowly in you, and they stay a long while. Change, even welcome change, can unsettle you until a new routine has had time to settle in.
Gemini MoonTalks it through until the feeling has a nameFeelings, for a Moon in Gemini, become clear once they're put into words. When something upsets you, you might text three friends, fill two pages of a journal, or argue both sides out loud while folding laundry. Silence can feel heavier than the problem itself. Moods shift with new information, sometimes within the hour, and you feel safest when you can understand what's happening and say it out loud to someone who answers back.
Cancer MoonRemembers how every room feltThe Moon rules Cancer, so astrologers often describe this placement as the Moon at home. Feelings run deep, protective, and tied to memory. You might keep every birthday card in a shoebox or tear up at a song that used to play in the kitchen when you were small. When you're hurt, you tend to pull into your shell for a while, cooking, rearranging a shelf, or nesting under blankets until the world feels safe again.
Leo MoonNeeds a little applause to feel at homeA Leo Moon wants feelings to be seen and answered with warmth. When you're upset, advice alone can feel cold; you'd rather someone notice, sit down, and say they're on your side. You recover by doing something that makes you feel bright again: dressing up for no reason, singing loudly with the windows down, planning a weekend that has a little sparkle. Being overlooked tends to hurt more than being criticized.
Virgo MoonSettles the nerves by making a listWith the Moon in Virgo, you calm down by sorting things out. Stress might send you to clean out the fridge, color-code the calendar, or read product reviews until midnight. Order feels like relief, and a clear plan makes the room stop spinning. You may also question your own reactions harshly, asking whether you're overreacting, before you give yourself permission to feel what you already feel.
Libra MoonBreathes easier when the room is at peaceA Libra Moon finds safety in harmony. When there's tension in the room, you feel it physically and want it resolved, sometimes smoothing things over before checking how you feel yourself. Pleasant surroundings, kind words, and fair treatment help you relax. Venus rules the sign, so beauty matters here as comfort: fresh flowers, a tidy desk, a calm voice. Talking a feeling through with one trusted person helps you understand it.
Scorpio MoonKeeps the deepest feelings in a locked drawerA Scorpio Moon feels deeply and keeps most of it private. Emotions run strong, and you decide carefully who gets to see them. When you're hurt, you may withdraw, turn the event over for days, and only then decide what to do. Honesty and loyalty matter enormously, and a betrayal can leave a lasting mark. Feeling in control of what you reveal, and when, is what lets you relax.
Sagittarius MoonNeeds open sky to catch its breathFor a Sagittarius Moon, safety comes from space and possibility. When you're upset, you might take a long drive with no destination, plan a weekend somewhere you've never been, or bury yourself in a big new book. Being boxed in or micromanaged makes you restless fast. You recover by finding meaning in a hard experience, and sometimes by joking about it before you've fully felt it.
Capricorn MoonHolds steady now and feels it laterSaturn rules Capricorn, and a Moon here handles feelings with restraint. You may stay calm and useful in a crisis, then feel the full weight days later, often while doing something ordinary like loading the dishwasher. Structure, routines, and clear goals steady you. Under stress you might work longer hours, update the household spreadsheet, or make a plan with three backup plans. Showing vulnerability can feel like a risk you'd rather not take.
Aquarius MoonMost at home among friends who leave roomAn Aquarius Moon settles best with plenty of room around it. You may process a feeling by stepping back and thinking about it, sometimes reading three articles on the topic before admitting it hurt. When upset, you might go quiet or reach for friends rather than family. You like being understood without being crowded, and heavy emotional pressure, even well-meant, can make you pull back to get some air.
Pisces MoonSoaks up the room like a spongeA Pisces Moon picks up on everything around it. You may sense the mood in a room before anyone has said a word, and leave a party carrying feelings that aren't yours. When upset, you might retreat into music, art, a long shower, or sleep, needing quiet to sort out what belongs to you. Gentle surroundings help you settle, and a harsh comment can echo in your head for days.
What a Moon sign is
The Moon circles the Earth in about 27.3 days and spends a little over two days in each sign. Whichever sign it occupied at the moment you were born is your Moon sign.
In astrology the Moon is the private you: how you react when you are tired, hurt or relaxed, what you need in order to feel safe, and how you act around the people closest to you.
Reading your Moon without a birth time
The Moon travels 12 to 15 degrees a day. If it stayed in one sign all day, your Moon sign is certain even without a time. On about four in ten days it changes signs, and the calculator lists both. Read the two descriptions and see which one sounds more like you off the clock.
Why other sites may disagree
Most differences come from time zones and daylight saving time. US clocks have shifted many times, including year-round War Time from 1942 to 1945, and some states and counties have opted out. The calculator applies the historical rules for your birthplace and shows the UTC offset it used.
