How it works
What is a Moon sign?
Your Moon sign describes your emotional instincts, what makes you feel safe and how you show care. Because the Moon moves about 13° a day, your birth time makes the answer reliable.
Your big three
Three signs, three different stories.

Your first impression: how you meet new people and situations.
The other planets
