Calculate the Moon’s zodiac sign for a recorded time, or check the full local day when the birth time is unknown. Interpretive descriptions are astrological tradition, not medical or psychological assessment.
Direct answer
Your Moon sign is the zodiac sign containing the Moon at birth. With a recorded time, Moira returns the computed sign, degree, and lunar phase; without one, it checks the beginning and end of the full local date and reports whether the sign is stable or ambiguous.
While the Sun travels through one zodiac sign each month, the Moon is the fastest-moving body in our sky. It orbits the Earth in approximately 27.3 days, spending just 2.5 days in each zodiac sign. This swift orbital velocity makes the Moon your most intimate, fluctuating, and responsive astrological marker.
The Moon travels roughly 13.2 degrees across the zodiac every single day (more than half a degree per hour). If you were born on a day when the Moon crossed from one sign into the next, an exact birth hour and minute is vital to pinpoint your true emotional sign.
If the Sun represents who you are learning to become through conscious effort, the Moon is traditionally associated with habits, emotional responses, familiar comforts, and memory. These are symbolic interpretations, not claims about neurology or ancestry.
Classical astrology ranks the Moon's ease of expression: it is in its Domicile in Cancer, Exalted in Taurus (abundant stability), in its Detriment in Capricorn, and in its Fall in Scorpio (deep, turbulent emotional transformation).
Your Moon sign describes the qualitative flavor of your feelings, but your Birth Moon Phase is the angular distance between the Sun and Moon. Astrologers use the eight named sectors below as an interpretive framework:
Individuals born under a waxing Moon (New, Crescent, First Quarter, Gibbous) tend to be impelled by outward growth, pioneering building, creating new structures, and asserting subjective will into the physical world.
Those born under a waning Moon (Full, Disseminating, Last Quarter, Balsamic) are guided by dissemination, harvesting, philosophical synthesis, teaching, and releasing outdated paradigms back into the collective stream.
In roughly 80% of days, the Moon remains in the same zodiac sign for the full 24-hour period. However, on the days when the Moon changes signs (every 2.5 days), someone born in the morning might have a Cancer Moon while an evening birth yields a Leo Moon. If you do not know your exact hour, check whether the Moon transitioned signs on your birth date.
Your Sun sign is your conscious ego, solar vitality, and what you aspire to accomplish in the external world. Your Moon sign is your unconscious, nocturnal self: what you need when you are exhausted, sick, heartbroken, or in intimate relationships behind closed doors.
“Void of course” has multiple traditional definitions and depends on the planets, aspects, and boundaries admitted by a method. Some astrologers read it symbolically as independence or nonconformity; it does not establish psychological traits or immunity to social pressure.
