A natal birth chart maps where the Sun, Moon, and planets were at your exact moment of birth. It reveals personality themes, emotional needs, communication style, and life areas — not daily predictions.
This free birth chart calculator uses precise NASA JPL-validated astronomical calculations from your birth date, time, and location. You get a free astrology chart with houses: planetary positions in signs, all twelve house placements, your Rising sign, and major aspects.
Your chart is yours to keep. Save the chart wheel as an image, use the birth chart download to take the full reading with you, or turn the same chart into a printable birth chart poster you can frame — all from the result page, no signup required to generate the chart.
Don't know your exact birth time? You can still calculate your chart — every planet's sign is valid without a time except occasionally the Moon's. You'll lose the Rising sign and houses (those need the exact minute), and the calculator is honest about that rather than inventing them.

Birth chart FAQ
What is a natal chart reading?
A natal chart reading interprets the positions of the Sun, Moon, planets, and houses at your exact moment of birth. It reveals personality themes, strengths, and life areas—not predictions. Our free tool generates your chart with expert insights.
How accurate is this natal chart?
Accuracy depends on your birth data. With exact date, time, and location, we use precise ephemeris calculations. Birth time determines your Rising sign and house placements—the more precise, the more accurate your chart.
Can I generate a natal chart without birth time?
Yes. Use 12:00 PM as an approximation. You'll get accurate planetary positions in signs, but your Rising sign and house placements may be off. Check your birth certificate for the most accurate reading.
What does a natal chart show?
Your natal chart shows planetary positions in signs and houses, your Rising sign, and major aspects (angles between planets). Each element reveals different life themes—personality, emotions, communication, relationships, and more.
Can I calculate my birth chart without my birth time?
Yes. Enter just your birth date and place and you'll get every planet's sign — the Sun through Pluto are valid without a time, with the Moon occasionally ambiguous on sign-change days. The Rising sign, houses, and Midheaven require the exact minute, so the chart omits them honestly instead of defaulting to noon.
Can I print or download my birth chart?
Yes. From the result page you can save the chart wheel as an image, download the full written chart, or create a printable birth chart poster — a high-resolution SVG, PNG, and PDF of your actual chart, sized to frame. The free chart itself never expires or sits behind a signup.
Which house system does this calculator use?
Charts are calculated with the widely used Placidus house system. If a planet sits near a house border, be aware that other systems (like whole-sign houses) may place it in the neighboring house — both are legitimate conventions, and the planet's sign and degree are identical in every system.
