What is a birth chart?

In short: a birth chart (also called a natal chart) is the map of the sky at the exact moment and place of your birth. This free birth chart calculator places your planets, your Ascendant and your houses in seconds, then gives you a first reading.

Each planet sits in a sign (its colour) and a house (the area of life where it acts); their aspects describe the tensions and supports that make you up. The calculation gives the map; the deeper reading comes next, by connecting each element to your story. A free natal chart needs only three details: your date, time and place of birth, and the calculation itself is instant.

What this calculator gives you

  • Your 10 planets, from the Sun to Pluto
  • The North and South lunar Nodes, your axis of growth
  • Chiron and the asteroids Juno and Vesta
  • The Black Moon (true Lilith) and the Part of Fortune
  • Your Ascendant, Midheaven, Vertex and 12 houses
  • The major aspects between your planets

To learn how to weave all this into a coherent portrait, follow our guide: how to read a birth chart.

Frequently asked questions

What is a birth chart?

It is a snapshot of the sky at the exact moment of your birth, seen from your birthplace: the position of the Sun, the Moon, the planets, the Ascendant and the houses. It is the map of the strengths, needs and drives that make you up.

What do you need to calculate a birth chart?

Your date, time and place of birth. The time is essential: it sets your Ascendant and the position of the houses. Without an accurate time, your planets are calculated by sign, but not the Ascendant or the houses.

Is this birth chart calculation really free?

Yes, entirely free and instant, with no sign-up. The calculation is based on the Swiss Ephemeris. The personalised, in-depth reading happens in a consultation with Dorothée Casanova.

Can I get my birth chart with houses?

Yes. As long as you enter an accurate birth time, the calculator shows your 12 houses alongside your planets, your Ascendant and your Midheaven. Without a time, you still get your planets by sign, but not the houses.
