Rising and Moon Sign Estimator
This tool provides an estimation of your Rising (Ascendant) and Moon signs based on your birth details.
Please note that precise astrological calculations require complex ephemeris data, geographical coordinates (latitude and longitude), and specific house system algorithms, which are beyond the scope of a simple client-side script.
This calculator uses highly simplified approximations for illustrative purposes. For accurate results, consult a professional astrologer or a dedicated astrological software.
Understanding Your Rising and Moon Signs
In astrology, your birth chart is a snapshot of the sky at the exact moment and location of your birth.
It reveals key aspects of your personality, emotional nature, and life path. Among the most significant placements are your Sun sign, Moon sign, and Rising sign (Ascendant).
The Moon Sign: Your Emotional Core
Your Moon sign represents your inner world, emotions, instincts, habits, and subconscious reactions. It governs how you feel, nurture, and seek comfort. While your Sun sign describes your core identity and ego, your Moon sign reveals your emotional needs and how you process experiences on a deeper level. It often becomes more apparent in close relationships or when you're in a comfortable, private setting.
- Aries Moon: Impulsive, passionate, needs emotional independence.
- Taurus Moon: Stable, sensual, seeks comfort and security.
- Gemini Moon: Curious, communicative, needs mental stimulation.
- Cancer Moon: Nurturing, sensitive, deeply emotional, seeks security.
- Leo Moon: Expressive, dramatic, needs to feel special and appreciated.
- Virgo Moon: Practical, analytical, seeks order and perfection.
- Libra Moon: Harmonious, diplomatic, seeks balance and partnership.
- Scorpio Moon: Intense, private, deeply emotional, seeks transformation.
- Sagittarius Moon: Optimistic, adventurous, needs freedom and exploration.
- Capricorn Moon: Reserved, disciplined, seeks achievement and respect.
- Aquarius Moon: Independent, intellectual, seeks unique connections.
- Pisces Moon: Compassionate, intuitive, highly sensitive, seeks spiritual connection.
The Rising Sign (Ascendant): Your Outer Persona
Your Rising sign, or Ascendant, is the zodiac sign that was ascending on the eastern horizon at the precise moment of your birth. It represents your outer personality, your first impression, how others perceive you, and your initial approach to the world. It's often considered the "mask" you wear, influencing your physical appearance, mannerisms, and how you initiate new experiences. Because it changes approximately every two hours, an accurate birth time is crucial for determining your Rising sign.
- Aries Rising: Energetic, direct, pioneering, can appear assertive.
- Taurus Rising: Calm, steady, sensual, can appear grounded and reliable.
- Gemini Rising: Expressive, curious, adaptable, can appear witty and restless.
- Cancer Rising: Nurturing, sensitive, protective, can appear shy or caring.
- Leo Rising: Confident, dramatic, charismatic, can appear regal and attention-seeking.
- Virgo Rising: Practical, analytical, modest, can appear organized and helpful.
- Libra Rising: Charming, diplomatic, graceful, can appear balanced and social.
- Scorpio Rising: Intense, mysterious, powerful, can appear private and magnetic.
- Sagittarius Rising: Optimistic, adventurous, philosophical, can appear jovial and free-spirited.
- Capricorn Rising: Serious, disciplined, ambitious, can appear reserved and responsible.
- Aquarius Rising: Unique, intellectual, humanitarian, can appear detached and unconventional.
- Pisces Rising: Dreamy, compassionate, artistic, can appear gentle and ethereal.

// — Simplified Moon Sign Calculation —
// This is a highly simplified approximation. The Moon's movement is complex.
// Reference point: Jan 1, 2000, 00:00 UTC, Moon approximately in Aries (for illustrative purposes)
// Actual Moon position on Jan 1, 2000, 00:00 UTC was 15° Pisces. Let's adjust the reference.
// Let's use a more recent, verifiable ingress for a slightly better (but still approximate) starting point.
// Moon entered Aries on March 20, 2024, at 12:06 PM UTC.
// For simplicity, let's use a fixed reference date and a simplified average cycle.
// Moon spends approx. 2.5 days (60 hours) per sign.

// — Highly Simplified Rising Sign Calculation —
// This is a very crude approximation. Rising sign depends heavily on latitude, longitude, and time of year.
// It changes approximately every 2 hours.
// We'll assume Aries rising around 6 AM local time on the Spring Equinox (March 21st) for a mid-latitude.
// This will be highly inaccurate for most dates and locations.

hoursSinceBase += 24; // Wrap around for previous day
}
// Each sign is roughly 2 hours
risingSignIndex = Math.floor(hoursSinceBase / 2);
// Adjust for the actual date's position relative to the equinox.
// This is still a massive simplification. For example, on the Autumn Equinox, Libra would be rising at 6 AM.
// To make it slightly less arbitrary, let's try to factor in the month, but still very rough.
var monthOffset = Math.floor((birthMonth – 1) / 1); // Roughly 1 sign per month after March
