無料オンラインホロスコープ計算
生年月日と時間に基づいてあなたのホロスコープを生成します。
Calculate your natal birth chart — also called a horoscope wheel — using your exact birth date, time, and location. Your birth chart shows the positions of the Sun, Moon, and planets at the precise moment you were born.
The Big Three: Sun, Moon, and Rising
The Sun sign represents your core identity and ego. The Moon sign reflects your emotional nature and subconscious. The Rising sign (ascendant) — which requires your exact birth time — describes how others perceive you and is the starting point of your entire chart.
Birth chart calculations use the tropical (Western) astrology system. Results are provided for entertainment and personal reflection only.
