Free birth chart calculator
Enter your birth date, time and place. Your chart is calculated here, in your browser; nothing you type is sent anywhere.
What you get
Your Sun, Moon and Rising, every planet with its sign and house, your twelve houses and your aspects, drawn on a chart wheel.
How it is calculated
Your chart is calculated in your browser from your exact birth date, time and place, with the ephemeris from astronomy-engine and Chiron from the NASA JPL Horizons table. Houses are Placidus, or Whole Sign where you were born above the polar circle, as in the AstralRoots app.
Questions
What if I do not know my birth time?
Switch on I don't know my birth time. Your planets are placed at noon, and your houses and Rising sign are left out, as the app does.
Why do you need my birth place?
Your Rising sign and your houses depend on where on Earth you were born, and your birth time is turned into universal time through the place's time zone.
Is anything stored?
No. Nothing you type leaves your browser, and the site keeps no account. If you make a share link, your birth details travel in that link and nowhere else.
Is it free?
Yes. The calculator is free, with no sign-up.
