癸亥 Gui Hai Day Pillar: The great sea where all waters gather

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

Gui Hai is the last of the sixty pillars. Clear water (癸) over the great water of winter (亥): stem and branch are both Water and the stage is Peak. Like the sea where all waters gather, it is deep and wide.

At a glance

Personality

Excellent intuition and wisdom, great tolerance and deep feeling. Sitting on Rob Wealth, you are proud and competitive inside. The 戊 in 亥 combines with your 癸 Day Master (戊癸), so you embrace principle (the Direct Officer), and a Hurting Officer (甲) adds expression and wit. As the place that closes a cycle, you are keenly sensitive to endings, beginnings and change.

Love and partner

Rob Wealth sits in the spouse palace and you combine with the 戊 (Direct Officer) inside it. For women this joins the spouse star, read as a bond of deep attraction. With feelings this deep you can be swept along by a partner, so keep boundaries that protect you.

Work and money

Work that needs deep insight and intuition suits you: research, art, counselling, religion, planning. Money comes when you read the current and wait.

Cautions and advice

Overflowing water sinks easily into feelings and thoughts. You need goals and rules that channel the water, like Earth. The cold is strong, so keep warm people and activities, like Fire, close.

Day pillars that click, and day pillars that clash

Stems and branches both combine: 戊寅 Wu 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: 己巳 Ji Si, 丁巳 Ding 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 Gui Hai day come around?

Day pillars run in a sixty-day cycle. From October 2026 to the end of 2027, 癸亥 Gui Hai days fall 13 times: Tue, Dec 15, 2026; Sat, Feb 13, 2027; Wed, Apr 14, 2027; Sun, Jun 13, 2027; Thu, Aug 12, 2027; Mon, Oct 11, 2027; Fri, Dec 10, 2027; Tue, Feb 8, 2028; Sat, Apr 8, 2028; Wed, Jun 7, 2028; Sun, Aug 6, 2028; Thu, Oct 5, 2028; Mon, Dec 4, 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 Gui Hai day pillar

• 2026, the 丙午 Bing Wu year: the stem 丙 is your Direct Wealth and the branch 午 is your Indirect Wealth, so it is a year when money, practical gains and activity increase. 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 Wealth and the branch 未 is your Seven Killings, so it is a year when money, practical gains and activity increase. The stem clashes with your Day Master, so your thinking may waver. 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 Gui 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 Gui 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.
