In Western astrology, your Big 3 are the three most important placements in your birth chart — your Sun sign, Moon sign, and Rising sign (Ascendant). Together they paint a fuller picture than the Sun sign alone, which is the one most people know from horoscopes. This Big 3 Calculator works them all out from your exact birth details.

• Sun sign — your core identity, ego, and life purpose. It shows who you are at your center.
• Moon sign — your emotions, instincts, and inner world. It shows how you feel and what makes you feel safe.
• Rising sign (Ascendant) — the sign that was rising on the eastern horizon at your birth. It shapes your outward style and the first impression you give.

Tropical vs sidereal zodiac

The Big 3 uses the tropical zodiac that Western astrology follows, which is tied to the seasons. This is different from the sidereal zodiac used in Vedic (Hindu) astrology, which is tied to the fixed stars. Because of this difference, your Western Sun sign may not match your Vedic Rashi — both are correct within their own system.

Why birth time matters

Your Sun and Moon signs only need the date (and roughly the time for the Moon), but the Rising sign changes about every two hours, so an accurate birth time and place are essential for it. Select your birth city from the dropdown so the coordinates and timezone are correct.
