A practical introduction to the Four Pillars chart, including the year, month, day, and hour pillars and the role of true solar time.

Learn what a BaZi chart is, how the Four Pillars work, and why birth time, Day Master, hidden stems, and luck pillars matter in Chinese astrology.

The Day Master is the stem of the day pillar and the main reference point for reading Ten Gods and element relationships in a chart.

Learn what the Day Master means in BaZi, how to identify it, and how it shapes the reading of Ten Gods, element relationships, and chart themes.

The Ten Gods are relational labels that describe how other stems behave relative to the Day Master across companionship, expression, wealth, authority, and resource themes.

Understand the Ten Gods in BaZi, including companion, output, wealth, influence, and resource roles, and how they are derived from the Day Master.

Hidden stems are the elemental layers contained inside each earthly branch, and they often explain chart themes that visible stems alone miss.

Learn what hidden stems are in BaZi, why they matter in chart interpretation, and how they affect Ten Gods, element distribution, and pattern recognition.

Element distribution shows how wood, fire, earth, metal, and water appear across the chart, but the count only becomes useful when paired with the Day Master and chart structure.

Learn how element distribution works in BaZi, what the five elements reveal in a chart, and how visible stems, hidden stems, and timing cycles change the picture.

Luck pillars are ten-year timing cycles that extend the natal chart and help frame broader life periods, directional shifts, and recurring themes.

Understand how luck pillars, also called Da Yun, are calculated in BaZi and how they interact with the natal chart to frame major life periods.

BaZi calculator FAQ

What does this BaZi calculator show?

Horomo calculates the Four Pillars chart and shows the Day Master, visible stems, hidden stems, Ten Gods distribution, element distribution, and Da Yun luck pillars.

Why does birth place matter in a BaZi chart?

Birth place determines the timezone and local solar correction. Those values matter when the recorded birth time is close to a pillar boundary.

Can I use the calculator if I do not know my birth time?

Yes. Horomo can calculate the year, month, and day pillars without the hour pillar, and it marks the time-dependent areas as unknown.

What should I read after I generate my chart?

Start with the Day Master, then review hidden stems, Ten Gods, element distribution, and the current or upcoming luck pillars to understand the chart in context.
