Free birth chart calculator
What’s in your birth chart?
Your date, time and place of birth fix one sky, once. This works out where every body stood in it, to the degree, and draws it.
Your daily mainstream horoscope says: “You’re a Leo, so you’re a natural leader.”
That is one placement out of ten. Here are the other nine, the part of your chart each one falls in and how they line up with each other—computed from your birth moment, not your birth month.

What your chart includes
- Every planet, by sign and degree
- Sun through Pluto, each placed to the arcminute from the Swiss Ephemeris—the same positions professional software reads.
- Houses and your Ascendant
- Placidus houses, added when you know your birth time. Without one they are left out rather than guessed from noon.
- The aspects between them
- Which placements answer each other, and by what geometry—the structure that makes a chart more than a list.
- The wheel, drawn
- Your chart as a chart, on screen and downloadable as a PDF. Free, and yours to keep.
Your chart is the instrument. The sky moving over it is your timing.
A birth chart never changes—it is one moment, fixed. What changes is where the planets are today and which of your placements they touch. Your natal chart appears first on your dashboard, with daily scores below; every date you have already lived is free to check.
Questions about your birth chart
- Is it really free?
- Yes. The complete chart, the wheel and every placement cost nothing and need no sign-up or email. Past dates and today stay free; each set of birth details also unlocks its next 30 days once on your dashboard, and further ahead needs a one-time unlock, not a subscription.
- Do I need my birth time?
- No, and the chart tells you which parts it is sure of. Without a time: 9 of 10 planets at full precision; your rising sign and the parts of your chart need a birth time. We leave them out rather than fabricate them from a noon guess, which is what makes the rest of the chart worth trusting.
- What is the difference between a birth chart and a horoscope?
- A birth chart is yours alone: the whole sky at your birth moment, computed from your date, time and place. A horoscope is one twelfth of it—your Sun sign, read the same way for everyone who shares it. We publish both, and we label which is which.
