Moon sign
calculator
The Moon is your inner life: feelings, habits, the sense of home. It shows what feeds you, what throws you off balance and how you get yourself to safety when the world gets too loud. The Sun describes who you want to be. The Moon tells who you are when nobody is watching, with your reflexes, your longings and the stuff your dreams are made of.

What the Moon means
Your inner emotional world
The Moon is one of the two "lights" of your chart, the counterpart to the Sun. The Sun shows who you are. The Moon shows how you feel: your instincts and moods, your habits and what you need to feel safe. Think of the tea you make yourself after a hard day. It also stands for nurture, childhood and home in the widest sense.
Reading your Moon sign
Your Moon sign holds your emotional style, meaning what you need. A fire Moon usually wants excitement and freedom, an earth Moon stability and reliability. An air Moon needs space and exchange, a water Moon deep emotional closeness. You tend to show your Moon sign less than your sun sign. Even so, it explains your first, instinctive reactions best.
Finding your Moon sign: why the date is almost always enough
The Moon is the fastest body in the chart. It circles the zodiac in a little over 27 days, so it changes sign roughly every two and a half days. For most birthdays the date alone pins the Moon sign. Only if you were born on a change-over day does the time matter, because the Moon can sit in one sign in the morning and in the next by evening. The table below shows how often that happens, with the real change-over days of the next two weeks. Your Moon sign is the second part of your Big Three, next to the Sun and the rising sign, and it describes what you need in order to feel safe.
Moon sign changes over the next 14 days
| From | Moon sign | Element |
|---|---|---|
| Nov 10 | Moon in Sagittarius | Fire |
| Nov 12 | Moon in Capricorn | Earth |
| Nov 15 | Moon in Aquarius | Air |
| Nov 17 | Moon in Pisces | Water |
| Nov 20 | Moon in Aries | Fire |
| Nov 22 | Moon in Taurus | Earth |
In 14 days the Moon changes sign 6 times. If your birthday falls on one of those days, add your birth time. The signs always follow zodiac order, and the elements fire, earth, air and water rotate along with them. What a Moon in each element means is covered on the pages for the fire Moon, earth Moon, air Moon and water Moon.
Moon sign, Moon phase, Sun sign: the difference
- Moon sign: the zodiac sign the Moon was in when you were born. It changes every 2–3 days.
- Moon phase: how much of the Moon was lit, somewhere between new and full. Find yours with the Moon phase calculator.
- Sun sign: your familiar zodiac sign, which stays the same for about a month.
A small exercise for today: the next time you are stressed, notice the first thing you do. Do you look for quiet, talk it through, tidy something or go outside? Then read your Moon sign and check how much of it fits. Your birth chart shows the Moon with its house and aspects; every other point is in the placements overview.
Are all Moon signs equally common?
Almost. Between 1940 and 2009 the range runs only from 8.32% (Pisces) to 8.35% (Virgo); an even split would be 8.33%.
The Moon passes through all twelve signs in 27.3 days and stays in one sign for 54 hours on average, sometimes 47 hours, sometimes 61 hours. Its speed depends on how close it is to the Earth. Because that closest point itself circles the zodiac in just under nine years, it all evens out over decades.
| Sign | Share 1940–2009 | Typical stay |
|---|---|---|
| Aries | 8.34% | 54 hours |
| Taurus | 8.33% | 54 hours |
| Gemini | 8.34% | 55 hours |
| Cancer | 8.33% | 55 hours |
| Leo | 8.34% | 55 hours |
| Virgo | 8.35% | 55 hours |
| Libra | 8.34% | 55 hours |
| Scorpio | 8.33% | 54 hours |
| Sagittarius | 8.34% | 54 hours |
| Capricorn | 8.33% | 54 hours |
| Aquarius | 8.32% | 54 hours |
| Pisces | 8.32% | 54 hours |
