甲子 Jia Zi Day Pillar: The great tree standing over cold water

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

Jia Zi is the first of the sixty pillars. A great tree (甲) stands over midwinter water (子): as water feeds a tree, this day pillar grows through learning and being cared for.

At a glance

Personality

Thoughtful and fond of learning. Like a straight tree, you have clear principles and pride, and the strength to start new things. Sitting on a Direct Resource, you understand quickly, learn well and easily receive help from elders or mother figures. The Bath stage gives rich feelings and a quiet charm, though your mood can sway your heart.

Love and partner

With a Direct Resource in the spouse palace, you are drawn to someone who understands and looks after you. Stability and conversation matter in love, and relationships last when you learn and grow together. The balance breaks if you only lean on your partner — or start lecturing them.

Work and money

Work that uses your mind and builds systems suits you: education, research, planning, publishing. Recognition through qualifications and expertise is your strongest path. Money comes less in one big win than as your skill and credibility build up.

Cautions and advice

A tree over winter water thinks a lot and can act late. Rather than waiting until everything is perfect, start small. People and surroundings that warm body and mind (Fire energy) are a great help.

Day pillars that click, and day pillars that clash

Stems and branches both combine: 己丑 Ji Chou. 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: 庚午 Geng Wu. 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 Jia Zi day come around?

Day pillars run in a sixty-day cycle. From October 2026 to the end of 2027, 甲子 Jia Zi days fall 13 times: Wed, Dec 16, 2026; Sun, Feb 14, 2027; Thu, Apr 15, 2027; Mon, Jun 14, 2027; Fri, Aug 13, 2027; Tue, Oct 12, 2027; Sat, Dec 11, 2027; Wed, Feb 9, 2028; Sun, Apr 9, 2028; Thu, Jun 8, 2028; Mon, Aug 7, 2028; Fri, Oct 6, 2028; Tue, Dec 5, 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 Jia Zi day pillar

• 2026, the 丙午 Bing Wu year: the stem 丙 is your Eating God and the branch 午 is your Hurting Officer, so it is a year when you express yourself and start new things. With your day branch: clashes your day branch — moves and changes, a busier mind.
• 2027, the 丁未 Ding Wei year: the stem 丁 is your Hurting Officer and the branch 未 is your Direct Wealth, so it is a year when you express yourself and start new things. With your day branch: Harm — small hurts pile up easily; Wonjin — needless friction.

2027 month by month

Saju months change at the solar terms, not on the 1st. For a Jia Zi 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: April (甲辰), August (戊申), January 2028 (癸丑). The month that clashes with it: June (丙午).

Zodiac signs that suit Jia Zi, and signs that clash

Counting from the day branch 子, the Ox (丑), Dragon (辰), Monkey (申) form a Six or Three Harmony and are read as easy matches; the Horse (午) 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.
