甲 Jia Wood Day Master: the Tall Tree

By Data Saju · Published · Updated

Jia Wood is the great tree: upright, reaching for the light and hard to bend. A Jia Day Master tends to stand on principle, think long-term and take the lead when something needs to be built from the ground up. In saju, the heavenly stem of your birth day — the Day Master — represents you. If your day pillar starts with 甲 (Jia, Gap in Korean), this page is about you.

Strengths

Blind spots

Work and career

You thrive where you can grow something over years — a team, a practice, a product, a career ladder. Education, planning, public service, construction and roles with clear responsibility suit you.

Love and relationships

Loyal and protective, you show love by being reliable. Partners who give you room to grow — and gently tell you when you are being rigid — bring out your best. In a saju chart, the spouse star for a Jia Wood Day Master is Earth (Wealth) for men and Metal (Officer) for women. The 己 Ji (Yin Earth) Day Master, your combining partner, tends to feel a natural pull toward you.

How your birth season changes you

The same Day Master behaves differently depending on the season (month branch) of birth.

Spring
February – April
Born in its own season, the Day Master is strong and self-reliant. The task is to express and share that strength rather than hold on to it.
Summer
May – July
You pour your energy into the season — expressive and productive, but watch your stamina.
Autumn
August – October
The season presses on you, so you grow through discipline and pressure. Find allies and protect your rest.
Winter
November – January
The season feeds you, so support and resources come easily. Beware of comfort turning into complacency.

Saju months follow the solar terms, and the last month of each season (Chen, Wei, Xu, Chou) carries Earth energy too.
