A few answers to help you understand
Enter your birth date, local time and city. The tool calculates your three signs, then offers a simple reading of your portrait and affinities.
How are affinities ranked?
The tool compares each of your three signs with the other person’s sign. Traditionally similar pairings come first; those calling for more adjustment follow. Tied results stay together. This is not a percentage chance of romantic success.
Is this a comparison of two birth charts?
No. This tool compares your trio with the other person’s Sun sign alone. A full comparison, called synastry, uses both birth charts. These affinities are symbolic and not scientifically validated: they do not determine whether a relationship will succeed.
What if I do not know my birth time?
Check the available option. The Sun and Moon are examined across the local day using the selected UTC offset. Possible signs are shown if a change occurs; no Ascendant is invented. A different offset can change the results.
Is my information stored?
Calculations run in your browser without an account or storage by this tool. Your city search is sent to geocoding services to find the place. Your birth date and time are not sent to them.

Free astrological trio calculator: discover your Sun, Moon and Rising signs
Calculate your Sun, Moon and Rising signs online
The astrological trio, often called the Big Three, brings together the Sun sign, Moon sign and Rising sign. Our free astrological trio calculator identifies these three reference points from your birth date, local time and city, directly in the browser and without registration.
The date is used to locate the Sun and Moon in the tropical zodiac. Time and place are essential for the Rising sign or Ascendant, the zodiac sign rising on the eastern horizon. Without an exact birth time, the tool does not invent an Ascendant. If the Sun or Moon changes sign during the day, it displays the possible signs so an approximate time is not presented as a certainty.
Understand the Big Three and its symbolic affinities
In astrological tradition, the Sun is associated with personal expression and motivation, the Moon with emotional needs and familiar responses, and the Ascendant with the way a person approaches new situations. Reading the trio means connecting these three layers rather than reducing a personality to one sign. The guide to the twelve zodiac signs helps compare their elements, modes and symbolic qualities.
The tool also offers affinities with the twelve signs through a simple educational grid. These results describe traditional relationships between signs; they are neither a compatibility percentage nor proof that a relationship will succeed or fail. Use them to formulate questions and compare nuances, then continue with the free step-by-step astrology course.
Astrological trio, natal chart and relationship compatibility
The Big Three is an accessible starting point, not a complete natal chart. A fuller reading also considers Mercury, Venus, Mars and the other celestial points, together with houses and aspects. Create this broader map with the free birth chart generator, then use the complete astrology guide to study each placement in context.
A true comparison of two birth charts, generally called synastry, requires the birth data and complete charts of both people. The affinities shown here compare your trio with another Sun sign only. Astrology is a symbolic interpretive tradition, not scientific proof, a diagnostic method or a certain prediction. Keep important relationship, medical, legal and financial decisions grounded in facts and qualified advice.
