Ding Si (丁巳) Day Pillar

The Day Master (日干) Ding (丁) has the energy of candlelight, being subtle and deeply focused. The Day Branch (日支) Si (巳) is intelligent and agile. Since the Day Branch has the same energy as the Day Master, the roots are solid and self-confidence is strong.

You get along with your spouse like a friend, but you should avoid power struggles. The Day Branch Si (巳) is the spouse palace, implying a spouse who is intelligent and agile.

In the Twelve Stages of Qi (十二運星), it corresponds to Imperial (帝旺), meaning your energy is at its peak, giving you strong independence and a refusal to bow to others.

As your energy is strong, beware of stubbornness.

Dingsi (Korean: Jeongsa) is a candle flame resting on hot Si fire at the Imperial stage (帝旺), which gives an unusual power to dig deep into one thing. Inside the branch, Wu earth as Hurting Officer (傷官) brings a sharp tongue and a critical eye, and Geng metal as Direct Wealth (正財) adds careful calculation and a practical sense for money. Research, analysis, technical specialties, lecturing or marketing—any work that turns insight into words—tends to suit it. Bing fire as Rob Wealth (劫財) sits there too, so money can drain away amid competition; steady, regular saving usually fits better than impulsive bets.

A Dingsi person may look calm on the surface, but once they give their heart it burns long and hot, like a candle that refuses to gutter. The Hurting Officer (傷官) energy lets them read words and gestures with precision, so their conversations are deep and witty. Their friendships are usually few but lasting, built on real confidences. Because Rob Wealth (劫財) is the branch's main qi, quiet rivalry or jealousy over partners and friends can surface, and one cutting remark can leave a mark. Waiting a day before speaking when emotions flare is a small habit that keeps the flame from scorching what it warms.

Since Dingsi is fire sitting on fire at the Imperial stage (帝旺), its fortune opens less by adding force and more by regulating it. Its napeum, Sand-Within Earth (沙中土), is soil that receives the heat; in practice this means building containers that cool passion into finished work. Turning thoughts into tangible forms—essays, reports, pieces of craft—lets the Hurting Officer talent become real achievement. Using the carefulness of Direct Wealth (正財) to keep a budget or a clear calendar reveals where energy is leaking. And it helps to set fixed rest days rather than letting the candle burn at both ends.

Condensed warm light. Devoted, deeply focused, and possessing sharp intuition.
