What is a Moon sign?
Your Moon sign is the zodiac sign the Moon was in when you were born. While your Sun sign, the star sign everyone knows, is linked to your conscious self, in astrology the Moon speaks to your emotions, habits and what gives you a sense of security.
A Moon sign calculator usually needs only your birth date. But the Moon moves about 13 degrees a day and changes sign every two to three days. If that change fell on your birthday and you don't know the time, we show you both possible signs.
Read both descriptions and keep the one that feels truer to you. Here astrology is a tool for self-reflection, not a scientific claim.

Questions
What is a Moon sign?
It is the zodiac sign the Moon was in when you were born. In astrology it stands for your emotional world: what makes you feel safe, how you react under stress and what you need to feel at ease.
How is it different from my star sign?
Your usual "star sign" is your Sun sign: the Sun spends about a month in each sign. The Moon is much faster and changes sign every two to three days, which is why people with the same star sign often have different Moon signs.
Do I need my birth time for my Moon sign?
It helps. The Moon moves about 13 degrees a day, so it can change sign during a single day. Usually the date is enough. If the change happened on your birthday and you don't know the time, we show you both possible Moon signs.
Is it really free?
Yes. Your result shows up straight away, with no email needed: the chart wheel, your Sun, Moon and rising sign, all the planets, the elements and, if you know your birth time, the houses. Everything else is optional.
How accurate is it?
We compute positions with astronomical formulas, accurate to a fraction of a degree, using the tropical zodiac and Placidus houses (whole-sign houses at polar latitudes). The interpretation is astrology: a symbolic system for reflecting on yourself, not science and not a prediction. Keep what helps and leave the rest.
What happens to my data?
On the free calculators, your birth details are processed on our servers in the EU for that one calculation and are not stored. Your browser remembers your last entry locally on your device. We only store them (in the EU) if you continue to the personal report and give us your email. They are never sent to ad networks or tracking pixels. The full details are in the Adriatic Apps d.o.o. privacy policy.
