What are my Sun, Moon and rising signs?
Your Sun, Moon and rising signs are often called your Big Three. They describe three different placements at birth. In Western astrology, the Sun is associated with identity, the Moon with emotional needs, and the rising sign with your approach to the world. They are symbolic interpretations, not personality test results.
What information do I need?
Enter your birth date, local clock time and birthplace. The place is needed to interpret the recorded time correctly and to calculate the eastern horizon. Use the time as recorded at birth; do not convert it to UTC or adjust daylight saving yourself.
What if I do not know my birth time?
You can often identify a Sun sign from the date. The Moon can change signs during a day, so the calculator may show two possibilities. A rising sign cannot be determined reliably without a birth time. Do not use noon as if it were a known birth time.
Is the Ascendant the same as the rising sign?
Yes. Ascendant is the technical name for the point of the zodiac rising on the eastern horizon. Its sign is your rising sign. It changes roughly every two hours on average, but the rate varies with latitude and sign.
Is this a complete birth chart?
No. La Lune calculates the Big Three. A complete natal chart also includes other planets, houses and aspects. We use the tropical zodiac, common in Western astrology; sidereal systems can give different signs. Chinese zodiac and Matrix of Destiny results are separate traditions, not additional parts of the Big Three.
