Frequently Asked Questions
What is a natal chart?
A natal (birth) chart is an astrological map of the sky at the exact moment and location of your birth. It shows the positions of the Sun, Moon, and planets across the 12 zodiac signs and 12 astrological houses. Astrologers interpret these positions as symbolic influences on personality and life themes.
Why does my birth time and location matter?
The Ascendant (rising sign) and house positions change every ~2 hours as the Earth rotates. An inaccurate birth time shifts house cusps and the Ascendant, significantly altering the chart interpretation. Location determines the local horizon, which anchors house divisions.
Is astrology scientifically valid?
No peer-reviewed scientific evidence supports astrological predictions. Natal charts are a traditional symbolic system, not an empirical science. This tool is provided for entertainment, self-reflection, and cultural interest. Life decisions should not be based solely on astrological interpretation.
