Moon sign calculator
Your Moon sign describes your emotional needs: what makes you feel safe, how you react under stress and how you like to be comforted. The Moon changes sign every two to three days, so a birth date is usually enough. If it changed sign on your birthday, we will tell you, and a birth time settles it.
What your Moon sign means
Your Moon sign describes your emotional world: what makes you feel safe, how you react under stress and how you like to be comforted. Many astrologers consider it as important as your sun sign, especially in love, because it shapes the everyday texture of a relationship.
The Moon moves about 13 degrees a day and changes sign every two to three days. If you don't know your birth time, the calculator uses midday and tells you when your Moon might be in one of two signs that day.
Moon sign compatibility
When your Moon harmonizes with a partner's Moon or Sun, home life tends to feel easy and soothing. When Moons clash, it usually means you comfort yourselves in different ways: one wants space, the other wants closeness. Knowing that is half the work. Our birth chart compatibility guide explains how the Moon fits with Venus, Mars and the rest of the chart.
