Serena Williams — BaZi Chart Analysis

Serena Williams is widely regarded as one of the greatest women’s tennis players in history. She held the WTA world No. 1 singles ranking for 319 weeks, finished year‑end No.

The chart, as computed

The chart below is computed rather than looked up. Solar terms set the Month pillar and 立春 sets the Year pillar, so neither follows the Gregorian calendar, and a birth date close to either boundary lands differently than a naive reading of the date would suggest.

Day Master: 丁 (Ding, yin Fire). The engine reads this chart's day master as somewhat weak, in a 偏财格 (Pian Cai) structure — a chart organised around opportunity rather than salary.

This is one of the minority of profiles here with a recorded birth hour, so all four pillars are computed and the hour column below is real rather than inferred.

What the ten gods put where

• Year stem — 偏财 (Pian Cai): opportunistic wealth — the deal rather than the salary.
• Month stem — 比肩 (Bi Jian): the peer — self-parity, rivalry, independence.
• Hour stem — 正财 (Zheng Cai): steady wealth — earned, incremental, held.

Ten Gods describe relations. The label attaches to a stem only in relation to the Day Master, so nothing in the list above generalises to everyone sharing a Ding day master — it generalises to charts with this configuration, which is a much smaller set.

The branch relations the engine found

• 六害 · a harm — 酉 (You) / 戌 (Xu), in the year and hour branches. A friction relation — attrition rather than collision.
• 六破 · a break — 未 (Wei) / 戌 (Xu), in the day and hour branches. A destabilising relation, weaker than a clash.
• 自刑 · a self-punishment — 酉 (You) / 酉 (You), in the year and month branches. A branch repeated against itself.

Reading it

A somewhat weak Ding Fire day master in a Pian Cai structure, with Pian Cai on the year, Bi Jian on the month and Zheng Cai on the hour — both wealth registers plus the peer god, across all four pillars. The branch layer is the difficult part: a You–Xu harm, a Wei–Xu break, and a You–You self-punishment, three friction relations and no combination to relieve them. The tradition reads that as a chart whose resources are real and whose base keeps having to be re-established, which is a structural description rather than a narrative one. All four pillars are present.

What this page does not claim

What is above is a configuration, described. It is not a causal account of anyone's life, and nothing here reasons backwards from a documented outcome to the chart feature that would have foretold it — that move is the standard way this genre goes wrong, and it is avoided deliberately. Birth records are imperfect too, and where the hour is missing this page leaves it missing.

This is not a substitute for medical, financial or legal advice.

Work out your own chart

To compare this against your own chart, run it through the BaZi chart calculator — it uses the same solar-term boundaries as the table above. Definitions for anything unfamiliar are in the BaZi glossary, and the celebrity index lists the other charted figures.
