What does the moon sign mean?

In astrology, the Moon represents your emotional world: how you react inside, what makes you feel secure, how you nurture and how you want to be nurtured. While the Sun shows who you want to become, the Moon shows what you need to feel at peace.

Do I need my birth time?

It helps, but it isn't always essential. The Moon changes signs about every two and a half days. If you don't know your birth time, the calculator checks the whole day: if the Moon didn't change signs, your result is certain; if it did, it shows you both options.

What is your birth moon phase?

Besides the sign, astrology looks at which phase the Moon was in when you were born: new, waxing, full, or waning. Each phase describes an approach to life, from the drive to begin to the wisdom of letting go. You can follow the Moon each day in the Lunar Compass.

Frequently asked questions

How often does the Moon change signs?

About every two and a half days, because it travels through the whole zodiac in roughly 27.5 days.

Why don't I identify with my sun sign?

That's very common. If your Moon or rising sign is in a very different sign from your Sun, it may weigh more heavily on your day-to-day personality.

Does the moon sign influence a relationship?

In astrology, the Moon is key to emotional compatibility. If you want to compare your Moon with someone else's, try the couples synastry calculator.
