Your Chinese zodiac animal is only the surface of Bazi. The full chart is built from four pillars and the five elements.
Bazi uses the year, month, day and hour of birth. Each pillar consists of two parts, and the entire chart is viewed through the interactions of the elements, season of birth, structures and time periods. Therefore, two people of the same year can have completely different charts and different interpretations of money, relationships, work or ways of acting.
If you are new to the system, start with Complete Bazi Chart. For a couple, there is Bazi Compatibility, where two complete structures are compared, rather than only two personal elements. Bazi Year Forecast shows how incoming periods interact with your birth chart. Turning points expand the horizon to the next decade, while Date Selection focuses the question to a specific event and available days.
Bazi's strength is its combination of a stable birth chart and changing time cycles. For one question about a current situation, Horary, Tarot or Runes may be more direct. If you want to explore a person through planets and houses - Natal chart. If your main interest is Vedic dashas and nakshatras - Kundali.
In Omnia, Bazi is not calculated by the simplified calendar rule “a new month has begun, so the pillar has changed.” The boundaries of the periods are determined by the position of the Sun, that is, by actual solar transitions, as required by the method. Then the four pillars and the interactions of the elements are calculated, and only then the interpretation is formed.
This is especially important for dates near period boundaries: a technical error in the underlying chart can change the entire reading. Omnia focuses specifically on the correctness of the underlying calculation. And the interpretation of Bazi itself remains a traditional symbolic method, and not a scientific prediction of the future.
