Free birth chart calculator

Your birth chart, computed transparently

We compute your planets, houses, and aspects from first principles — and show our work. No mysticism about the math; honesty about what the symbols mean.

Where were the planets when you were born?

If you don't know your birth time, we default to noon — the houses and Moon degree will be approximate.

No account, no email. Placidus houses by default; switch any time.

Signs only: houses need your time and place.

How we work

Astrology is a symbolic language, not a science. We're exact about the astronomy and honest about the interpretation.

  1. We compute first

    Positions come from our own engine, built on the open-source astronomy-engine and tested against Swiss Ephemeris (the library behind astro.com), U.S. Naval Observatory data and NASA's eclipse canon.

  2. We name the knobs

    Houses depend on the house system. Every chart says which one it used, and switching shows you exactly what moves.

  3. We say who wrote what

    Readings are drafted with software assistance. Then they are either edited by our writers or checked by an automated reviewer against our voice guidelines, and each block says which.
