Frequently Asked Questions
What is a birth chart?
A birth chart (or natal chart) is a map of the sky at the exact moment you were born. It shows the positions of the Sun, Moon, and planets in the zodiac signs, which astrologers use to interpret personality traits and life patterns.
How accurate is this birth chart calculator?
This calculator uses astronomical algorithms to compute planetary positions. For the most accurate results, enter your exact birth time from your birth certificate. Even without an exact time, the planetary signs (except the Moon) will be accurate for most births.
What planets are included in the birth chart?
The calculator shows positions for the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, along with their zodiac signs, degrees, retrograde status, and essential dignities. It also includes the North and South Nodes.
What is a lunar mansion?
A lunar mansion is one of 28 segments of the ecliptic that the Moon passes through during its monthly cycle. Each mansion has its own character and is used in traditional astrology for timing and electional purposes.
What are planetary aspects?
Aspects are angular relationships between planets (like conjunctions, oppositions, trines, and squares). They describe how planetary energies interact — whether they support each other or create tension.
What does retrograde mean?
When a planet appears to move backward in the sky (from Earth's perspective), it's in retrograde. Astrologically, retrograde planets suggest areas where we review, reconsider, or experience delays.
What house systems are available?
This calculator supports Whole Sign, Equal, and Placidus house systems. Whole Sign assigns each house to a full zodiac sign starting from the Ascendant. Equal divides the ecliptic into 30° segments from the Ascendant. Placidus uses time-based calculations for more precise house cusps.
What are the Ascendant and Midheaven?
The Ascendant (ASC) is the zodiac sign rising on the eastern horizon at your birth — it shapes your outward personality. The Midheaven (MC) is the highest point of the chart and relates to career, public image, and life direction.
