己巳 Ji Si Day Pillar: Fertile fields in the sunshine

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

Ji Si is fertile soil (己) warmed by early-summer sun (巳). Fire warms Earth and the stage is Peak, so this pillar is stronger than it looks.

At a glance

Personality

Diligent and considerate, with practical sense and a capacity to learn. Sitting on a Direct Resource, you understand well and grow with help from those around you. Quiet as you seem, you have clear standards and a hidden stubborn streak.

Love and partner

With a Direct Resource in the spouse palace, you want a relationship where you look after each other, and you open up deeply to someone who cherishes you. Keep a little distance so care does not turn into interference.

Work and money

Work that cares for people and keeps systems running suits you: education, administration, counselling, healthcare, licensed professions. Building skill steadily and being recognised for trust is your path. You save steadily.

Cautions and advice

You want to stay where it is comfortable and tend to postpone change. Taking care of everything can overload you, so decide how far your responsibility goes. Hot earth needs rest that cools it like water.

Day pillars that click, and day pillars that clash

Stems and branches both combine: 甲申 Jia 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: 乙亥 Yi 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 Ji Si day come around?

Day pillars run in a sixty-day cycle. From October 2026 to the end of 2027, 己巳 Ji Si days fall 13 times: Mon, Dec 21, 2026; Fri, Feb 19, 2027; Tue, Apr 20, 2027; Sat, Jun 19, 2027; Wed, Aug 18, 2027; Sun, Oct 17, 2027; Thu, Dec 16, 2027; Mon, Feb 14, 2028; Fri, Apr 14, 2028; Tue, Jun 13, 2028; Sat, Aug 12, 2028; Wed, Oct 11, 2028; Sun, Dec 10, 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 Ji Si day pillar

• 2026, the 丙午 Bing Wu year: the stem 丙 is your Direct Resource and the branch 午 is your Indirect Resource, so it is a year when learning, paperwork and support come in. 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 Indirect Resource and the branch 未 is your Friend, so it is a year when learning, paperwork and support come in. 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 Ji 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 Ji 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.

Frequently asked questions

How common is the Ji Si day pillar? Day pillars repeat every sixty days, so about one person in sixty (1.7%) is born on a Ji Si day. The next Ji Si day is Mon, Dec 21, 2026.

What is 2027 like for a Ji Si day pillar? The 2027 丁未 Ding Wei year brings Indirect Resource and Friend, a year when learning, paperwork and support come in. Your actual year also depends on your luck pillar and whole chart, which your free reading shows.

Which zodiac signs match a Ji Si day pillar? By the day branch, the Ox (丑), Monkey (申), Rooster (酉) suit it and the Pig (亥) tends to clash.

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.
