乙巳 Yi Si Day Pillar: A flower in full bloom in the sun

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

Yi Si is a flower (乙) in full bloom under early-summer sun (巳). Like a sunlit flower, this pillar is radiant and richly expressive.

At a glance

Personality

Witty and a good talker, skilled at expressing yourself. Sitting on a Hurting Officer, you are creative with excellent taste. The 庚 in 巳 combines with your 乙 Day Master (乙庚), so you embrace principle (the Direct Officer) even within free expression. The Bath stage gives charm and rich feelings.

Love and partner

A Hurting Officer sits in the spouse palace and its 庚 (Direct Officer) combines with you. For women this joins the spouse star, read as a bond of strong attraction. Conversation and fun matter in love, but words can run ahead and hurt, so soften them first.

Work and money

Work that needs expression and taste suits you: broadcasting, art, design, marketing, education. Money follows when you make your talent known.

Cautions and advice

A flower over fire burns through energy quickly. Keep learning and rest — the Water that soaks your roots — close. Make plans so you do not start and drop things with your mood.

Day pillars that click, and day pillars that clash

Stems and branches both combine: 庚申 Geng 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: 辛亥 Xin 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 Yi Si day come around?

Day pillars run in a sixty-day cycle. From October 2026 to the end of 2027, 乙巳 Yi Si days fall 13 times: Fri, Nov 27, 2026; Tue, Jan 26, 2027; Sat, Mar 27, 2027; Wed, May 26, 2027; Sun, Jul 25, 2027; Thu, Sep 23, 2027; Mon, Nov 22, 2027; Fri, Jan 21, 2028; Tue, Mar 21, 2028; Sat, May 20, 2028; Wed, Jul 19, 2028; Sun, Sep 17, 2028; Thu, Nov 16, 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 Yi Si day pillar

• 2026, the 丙午 Bing Wu year: the stem 丙 is your Hurting Officer and the branch 午 is your Eating God, so it is a year when you express yourself and start new things. 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 Eating God and the branch 未 is your Indirect Wealth, so it is a year when you express yourself and start new things. 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 Yi 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 Yi 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.
