BaZi Chart Calculator FAQ
What is a BaZi chart calculator?
A BaZi chart calculator converts your birth year, month, day, hour, and birthplace into the Four Pillars of Destiny. OpenBAZI calculates the Heavenly Stems, Earthly Branches, Five Elements, Day Master, and Luck Pillars used in traditional Chinese astrology.
Is the OpenBAZI chart calculator free?
Yes. You can generate a basic BaZi chart for free. Advanced AI interpretation, detailed reports, and consultation features may use credits after the chart is generated.
Why does birth time matter in BaZi?
Birth time determines the Hour Pillar, which adds important detail about later-life patterns, children, ambitions, and hidden tendencies. An exact birth time makes the Four Pillars reading more complete.
What is a Day Master in BaZi?
The Day Master is the Heavenly Stem of your day pillar. It is the reference point for reading personality, useful elements, career tendencies, relationship patterns, and timing in a BaZi chart.
Can BaZi predict my future?
BaZi is best used as a timing and self-understanding tool. It highlights tendencies, cycles, opportunities, and pressure points rather than guaranteeing fixed events.
