A "Moon Sign" refers to the zodiac sign that the Moon was in at the time of a person's birth. It is an essential part of astrology, alongside the Sun Sign, and is believed to influence a person's emotions, instincts, and inner self. While the Sun Sign represents one's core identity, the Moon Sign reflects deeper feelings and subconscious reactions. To determine your Moon Sign, you need your birth date, time, and location. The Moon moves through the twelve zodiac signs approximately every 2.5 days, making it crucial to have accurate birth information. Understanding your Moon Sign can provide insights into your emotional landscape and how you relate to others.
