Calculate your birth chart
Astrology is a symbolic interpretation, not a scientifically proven prediction. Astronomical positions are calculated with an analytical method.
What your birth chart shows
Sun: your core and life force. Moon: your feelings and inner need for security. Ascendant: how you appear outwardly and how you start new situations. Planets: different areas of life, from communication to responsibility. Houses: the areas of life where these energies show up. Aspects: the connections between planets.

Frequently asked questions
Do I need my exact birth time?
Yes, for ascendant and houses. Without an exact time, planetary positions can still be calculated, but ascendant and houses are not reliable. Then use “My birth time is unknown”.
Is it free?
Yes. The calculator is free and needs no registration.
Are my birth details stored?
No. Calculation runs through a private API, and birth details are not stored or logged.
What is a birth chart?
A birth chart is the map of the sky at the moment of your birth: planet positions, ascendant, houses and aspects, each in a sign and a house.
What do I need for the calculation?
Birth date, birth time if possible, and birthplace. Latitude, longitude and timezone are derived from the birthplace.
What is the difference between sun sign, moon sign and ascendant?
The sun sign describes your core and direction, the moon sign your emotional world, and the ascendant how you appear outwardly.
What happens if I do not know my birth time?
The calculation then openly uses noon. Planet positions remain usable, while ascendant and houses are honestly left out instead of guessed.
Can I save the result as PDF?
Yes. Use your browser print function to save the result as PDF or print it.
Is astrology scientifically proven?
No. Astrology is a symbolic interpretation, not a scientifically proven prediction. The positions themselves are calculated astronomically.
Does the calculator work on a phone?
Yes. It runs directly in the browser, without an app and without registration, on phone, tablet and computer.
