Your Moon sign is the zodiac region occupied by the Moon as seen from Earth when you were born. In astrology it is associated with emotional needs, habits and instinctive reactions. Because the Moon moves quickly, the correct time and UTC offset matter near sign changes.
The calculator maps the Moon’s geocentric ecliptic-of-date longitude to one of twelve zodiac sectors. Exact times are checked across ±2 minutes, approximate times across ±15 minutes, and unknown times across the full local date. It gives no single sign when that range crosses a boundary.
