FAQ
What is a birth chart?
A birth chart, or natal chart, is a snapshot of where the Sun, Moon, and planets sat at the exact moment and place you were born. It maps each planet into a zodiac sign and a house, and the rising sign on the eastern horizon. Astrologers read it as a symbolic portrait of your temperament and patterns.
Do I need my exact birth time?
For your planet signs, no — those barely move over a day. For your rising sign and house placements, yes: the ascendant changes roughly every two hours, so an accurate time matters. If you're unsure, the planet signs are still reliable; treat the rising sign as a best estimate.
Is this birth chart calculator accurate?
The astronomy is accurate: planetary positions come from a precise ephemeris and the rising sign from the standard ascendant formula. What a placement means for your life is interpretation, not measurement. Astrology is a symbolic system, so read the chart as a lens, not a forecast.
What is a rising sign?
Your rising sign, or ascendant, is the zodiac sign that was climbing the eastern horizon at your birth moment. It shapes first impressions, your instinctive style, and the layout of your houses. Many astrologers consider it as defining as your Sun sign for how you move through the world.
