無料オンライン月星座計算機
生年月日からあなたの月星座を発見します。
Calculate your Moon sign — the zodiac sign the Moon occupied at the exact moment of your birth. The Moon moves through each sign approximately every 2.5 days, making it the fastest-moving body in the birth chart after the Sun.
What your Moon sign means
While your Sun sign reflects your conscious identity, your Moon sign reveals your emotional instincts, inner needs, and subconscious patterns. It shows how you respond instinctively to the world and what you need to feel emotionally secure.
Moon sign calculations use the tropical (Western) astrology system. Results are provided for entertainment and personal reflection only.
