丁巳 Ding Si Day Pillar: A blazing brazier

By Data Saju · Published October 3, 2026 · Updated November 5, 2026

Ding Si is a flame (丁) rising over the fire of early summer (巳). Stem and branch are both Fire and the stage is Peak — hot, intense energy.

At a glance

Personality

Passionate and sharp; once absorbed, you dig in to the end. Sitting on Rob Wealth, you are competitive and proud, and Direct Wealth (庚) and a Hurting Officer (戊) in 巳 add skill and practical sense. Calm as you look, you carry a strong fire inside.

Love and partner

With Rob Wealth in the spouse palace, you meet equal, assertive partners. You love passionately but easily clash over who leads. Make a habit of talking calmly before hurt spreads like fire.

Work and money

Work that needs absorption and competition suits you: research, technology, art, sales, management. Money comes when you move actively but can leak away in competition, so manage it.

Cautions and advice

Strong fire overheats easily. When anger flares, step away for a moment to cool off. Rest and people that cool you calmly, like Water, keep the flame burning long.

Day pillars that click, and day pillars that clash

Stems and branches both combine: 壬申 Ren Shen. With a stem combination and a Six Harmony at once (天合地合), these pairs are drawn to each other and mesh naturally.

Stems and branches both clash: 癸亥 Gui Hai. The branches clash and the stems collide too, so methods and pace differ and tension arises easily — though such pairs can also spur each other to grow.

Real compatibility looks at both whole charts, each person's useful element and the luck you go through together, not one day pillar. See how compatibility works.

When does a Ding Si day come around?

Day pillars run in a sixty-day cycle. From October 2026 to the end of 2027, 丁巳 Ding Si days fall 13 times: Wed, Dec 9, 2026; Sun, Feb 7, 2027; Thu, Apr 8, 2027; Mon, Jun 7, 2027; Fri, Aug 6, 2027; Tue, Oct 5, 2027; Sat, Dec 4, 2027; Wed, Feb 2, 2028; Sun, Apr 2, 2028; Thu, Jun 1, 2028; Mon, Jul 31, 2028; Fri, Sep 29, 2028; Tue, Nov 28, 2028 (by the local calendar date). A day that repeats your own day pillar is read as a day when your Day Master is strong — some use it to start something important or to take stock.

What 2026 and 2027 mean for a Ding Si day pillar

• 2026, the 丙午 Bing Wu year: the stem 丙 is your Rob Wealth and the branch 午 is your Friend, so it is a year when your own drive and sense of competition grow. No combination or clash with your day branch, so the year runs fairly calmly.
• 2027, the 丁未 Ding Wei year: the stem 丁 is your Friend and the branch 未 is your Eating God, so it is a year when your own drive and sense of competition grow. No combination or clash with your day branch, so the year runs fairly calmly.

2027 month by month

Saju months change at the solar terms, not on the 1st. For a Ding Si day pillar we calculated the ten god of each month's stem and how the month's branch meets your day branch. Months that combine with your day branch: August (戊申), September (己酉), January 2028 (癸丑). The month that clashes with it: November (辛亥).

Zodiac signs that suit Ding Si, and signs that clash

Counting from the day branch 巳, the Ox (丑), Monkey (申), Rooster (酉) form a Six or Three Harmony and are read as easy matches; the Pig (亥) clashes with it, so pace and style differ. A zodiac sign is only the other person's year branch, so real compatibility needs both whole charts.

The facts table, the matching pillars, the dates, the 2026–2027 flow and the zodiac signs all come from the same engine as our readings; the month pillars were re-checked against the solar-term times. A day pillar is two of the eight characters in a chart, so the same day pillar reads quite differently depending on the year, month and hour of birth.
