Birth chart calculator
Sun through Pluto, the nodes, Chiron, Lilith, the Ascendant, Midheaven and houses, computed for the exact moment and place you were born, and then written as sentences rather than symbols.
What makes this one different
- It writes, it does not just draw. Every placement becomes a sentence that names where it came from: “from Moon in Scorpio”, “from Saturn square your Sun”.
- Two systems, one entry. The Chinese Four Pillars are cast from the same birth data and read next to the Western chart.
- A forecast with dates. The eighteen months ahead as windows with a start, an exact date and an end, exportable to your calendar.
- A score. Log your turning points and see how often the windows matched them. The number is shown whether it is good or bad.

No birth time?
Most of the chart still holds, and the app can narrow the time down from your own life events.
Questions
- Is the birth chart calculator free?
- Yes. Casting and reading the chart is free and needs no account; nothing is stored until you choose to keep it.
- How accurate is it?
- Planetary positions come from a built-in ephemeris accurate to well under a degree across the twentieth and twenty-first centuries, with houses computed for your exact coordinates and the time zone in force on your birth date.
Cast yours, to the minute
This page is written for a sign or a pillar. Your chart is written for the moment you were born: Western astrology and the Four Pillars read together, in plain words, with the year ahead as dated windows. It takes a minute and needs no account.
