Online cosmogram

Enter your date of birth to explore the positions of the Sun, Moon and planets. Add a time for a more precise calculation.

Planetary positions are calculated using NASA JPL astronomical ephemerides
Choose the UTC offset that applied at the place and date of birth, including daylight saving time if used. Without a birth time, we use midday at that offset; the Moon and positions near sign boundaries may be uncertain. This calculator shows planets and aspects, without houses or an Ascendant.

Two symbolic approaches to your birth date

Your cosmogram shows the sky. The Destiny Matrix connects the same date with 22 Arcana and themes of purpose, money and relationships. Explore both perspectives.

How this cosmogram calculator works

Cosmogramma uses NASA JPL ephemerides stored on its server: astronomical data describing the motion of celestial bodies. When you enter a date and time, the server calculates coordinates and draws the wheel from those positions. An unknown birth time introduces uncertainty about the positions at the moment of birth.

The chart includes ten celestial bodies, from the Sun and Moon to Pluto. Lines show aspects, the angles between them. Gold marks traditionally harmonious connections and reddish lines mark challenging ones. Retrograde motion is labelled separately. Learn how to read the symbols in our guide “What is a cosmogram?”.

Are the planetary positions calculated?
Yes. NASA JPL ephemerides are used for server calculations, with supported dates beginning in 1900.
Is a birth time needed?
It helps. Without one, the calculation uses midday. The Moon and any body near a sign boundary may have an uncertain birth-time position.
Is it free?
Yes. It is free and does not require registration.
How is this different from the Destiny Matrix?
A cosmogram uses planetary coordinates and astrological meanings. The Destiny Matrix uses the birth date and 22 Arcana in a numerology system. They are different symbolic approaches.
