丁亥 Ding Hai Day Pillar: A lighthouse on the night sea

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

Ding Hai is a lamp (丁) lit over the deep water of winter (亥). Like a lighthouse on a dark sea, it is quiet but lights the way.

At a glance

Personality

Careful and courteous, with excellent inspiration and intuition. Sitting on a Direct Officer, you have self-control, and the 壬 in 亥 combines with your 丁 Day Master (丁壬), so you grow close to the people near you. A Direct Resource (甲) in 亥 means you grow through learning and help. The Conception stage holds potential not yet visible.

Love and partner

A Direct Officer sits in the spouse palace and its 壬 combines with you. For women this joins the spouse star, read as deep affection with a spouse; men too keep their relationships responsibly. You do not say everything you feel, so a little more expression helps.

Work and money

Work that lights up people's hearts suits you: education, counselling, research, spirituality, culture. You are also valued for upholding principles within an organisation. Money follows position and trust.

Cautions and advice

Fire over water can make your heart unsettled and anxious. Supportive people and a regular routine keep the lamp from going out. Keep learning steadily — the Wood that feeds your fire.

Day pillars that click, and day pillars that clash

Stems and branches both combine: 壬寅 Ren Yin. 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: 癸巳 Gui Si. 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 Hai day come around?

Day pillars run in a sixty-day cycle. From October 2026 to the end of 2027, 丁亥 Ding Hai days fall 14 times: Mon, Nov 9, 2026; Fri, Jan 8, 2027; Tue, Mar 9, 2027; Sat, May 8, 2027; Wed, Jul 7, 2027; Sun, Sep 5, 2027; Thu, Nov 4, 2027; Mon, Jan 3, 2028; Fri, Mar 3, 2028; Tue, May 2, 2028; Sat, Jul 1, 2028; Wed, Aug 30, 2028; Sun, Oct 29, 2028; Thu, Dec 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 Hai 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. With your day branch: Three Harmony with your day branch — allies gather and strength builds.

2027 month by month

Saju months change at the solar terms, not on the 1st. For a Ding Hai 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: February (壬寅), March (癸卯), July (丁未). The month that clashes with it: May (乙巳).

Zodiac signs that suit Ding Hai, and signs that clash

Counting from the day branch 亥, the Tiger (寅), Rabbit (卯), Goat (未) form a Six or Three Harmony and are read as easy matches; the Snake (巳) 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.
