Questions
and Answers
What is a birth chart?
A birth chart (also called a natal chart) is a map of the sky showing planetary positions at your exact moment of birth. Your birth chart reveals your personality, strengths, life path, and astrological blueprint based on the zodiac signs, houses, and aspects.
How accurate is your birth chart calculator?
Our birth chart calculator uses Swiss Ephemeris, the gold-standard astronomical engine trusted by professional astrologers worldwide. We calculate planetary positions with NASA-grade accuracy, ensuring your natal chart is precise to the minute.
Do I need my exact birth time for an accurate birth chart?
Yes, your exact birth time is essential for accurate house placements in your natal chart. Even a few minutes difference can change your rising sign (ascendant) and house cusps. If you don't know your birth time, you can still generate a chart, but house positions won't be accurate.
