Birth chart calculator questions
What do I need to calculate my birth chart?
You need your birth date, birthplace, and ideally your exact birth time. The time determines your rising sign and houses; if you do not know it, you can still see the planets and signs with lower house confidence.
What is included in a natal chart?
A natal chart maps the Sun, Moon, planets, angles, houses, and aspects for the moment and place you were born. The useful part is how those placements interact, not just your Sun sign.
Is the birth chart calculator free?
Yes. Your chart and an initial personal reading are free. An account saves your chart so you can return to it and use it with compatibility and forecast features.
