Enter your birth date
Your moon sign depends on the date. No birth time needed – the moon stays ~2.5 days in the same sign.
What is the Moon Sign?
The moon sign is the zodiac sign the moon was in at the time of your birth. While the sun sign describes your core self and life drive, the moon sign reveals your emotional inner world – your instinctive reactions, deep needs and the way you give and receive care.
The moon changes signs every ~2.5 days and moves through all 12 zodiac signs in one synodic month (29.5 days). This means your moon sign can differ from your siblings' even if you are only a few days apart.
Moon Sign and Emotional Needs
Each moon sign describes what you need emotionally to feel safe, secure and balanced. Moon in Cancer needs family closeness and warmth. Moon in Aquarius needs intellectual freedom and independence. Moon in Capricorn feels supported through structure and achievement.
In relationships, the moon sign is often even more important than the sun sign: it shows how you express and receive love and care, what gives you security in conflicts and what hurts you.
Frequently Asked Questions about the Moon Sign
What is the moon sign?
The moon sign is the zodiac sign the moon was in at the moment of your birth. It shows your emotional inner world, your instinctive reactions, your needs for security and comfort – in short: how you really tick inside, apart from the outward presentation of your sun or ascendant sign.
What is the difference between sun sign and moon sign?
Your sun sign (star sign) is based on your birth date and describes your core self and life drive. The moon sign shows your emotional nature, unconscious patterns and needs. In relationships, the moon sign is often even more important than the sun sign because it shows what you need emotionally and how you give and receive care.
Do I need my birth time for the moon sign?
Usually not – the moon stays in the same sign for about 2.5 days. Only if you were born on a day when the moon changed signs could the birth time be decisive. In that case, we recommend the complete calculation in the UmbraLux app with birth time and location.
Which moon signs go well together?
Same elements often harmonize well: Moon in fire signs (Aries, Leo, Sagittarius) with other fire or air signs (Gemini, Libra, Aquarius). Water signs (Cancer, Scorpio, Pisces) and earth signs (Taurus, Virgo, Capricorn) also complement each other deeply.
What does Moon in Cancer mean?
Moon in Cancer is considered the strongest lunar position, as the Moon is the ruling planet of Cancer. People with this moon sign are deeply empathetic, nurturing and strongly shaped by family and home. Security and emotional comfort are their central needs.
