The Twelve Life Stages: Reading Your Day Master's Strength as a Life Cycle

By Data Saju · Published October 3, 2026 · Updated October 7, 2026

The twelve life stages (十二運星, also called the twelve growth phases) describe how strong your Day Master is in each of the twelve branches, using the image of a human life: born (Birth), rising to the top (Peak), fading (Severance) and conceived again (Conception) — an endless cycle.

The twelve stages

"Strength" is a rough measure of how alive your Day Master is in that place. Weak is not bad: places like Illness, Death and Tomb are read as other strengths — sensitivity, focus and accumulation.

Where the cycle starts: the Birth branch

Each Day Master has a fixed branch where its Birth stage falls. Yang stems (甲丙戊庚壬) count forward through the branches from there; yin stems (乙丁己辛癸) count backwards.

So 甲 Wood is at Birth in 亥, Bath in 子, Coming of age in 丑, Prosperity in 寅 and Peak in 卯. 乙 Wood goes backwards: Birth in 午, Bath in 巳, Coming of age in 辰.

Reading the stages by pillar

• Year pillar: childhood and the atmosphere of your family.
• Month pillar: young adulthood, social life and how you work.
• Day pillar: yourself and your closest relationship (your partner). The most-read place.
• Hour pillar: later life, children and long-prepared plans.

The same table applies to your 10-year and annual luck. Prosperity and Peak luck adds strength; Illness, Death and Severance luck is sometimes read as a signal to pace yourself.

Two cautions

Counting yin stems backwards (陰生陽死, "yin is born where yang dies") is debated between schools; some use the same places for yin and yang stems. And the twelve stages are a lighter, supporting indicator than the chart structure or useful element, so they never settle good or bad on their own.

The twelve stages in more detail

The twelve stages are one full turn: energy is born and grows, reaches its height, rests and is born again. Every stage has its bright side and its caution.

Birth (長生)

Where new life is born: innocence, curiosity and the fortune of being helped by those around you. Birth in the day branch is said to bring an easy bond with your partner and close people; met in your luck, new beginnings tend to go smoothly.

Bath (沐浴)

Where the newborn is washed — a time of being exposed and unsteady. Charm, sensitivity and a love of style, with plenty of trial and error. Like the Peach Blossom, it is read for both popularity and gossip.

Coming of age (冠帶)

The rite of putting on the cap and belt: confidence, the drive to step forward and a flair for presentation. Just watch for rushing ahead of yourself.

Prosperity (建祿)

Where you earn your own living: independence, solid skill and a stable career. With strength here you tend to make your place by your own effort rather than leaning on others.

Peak (帝旺)

Where energy is at its fullest: initiative, leadership and strong self-belief. With so much power, the key is keeping pace with others so it does not turn into stubbornness.

Decline (衰)

Past the summit, strength eases a little. In return comes the seasoned judgment, caution and steady conservatism of experience — the wisdom of keeping rather than overreaching.

Illness (病)

A place of frailty that shows as sensitivity and empathy. A gift for noticing others' pain and caring for them, for counselling and for art. Looking after your stamina is the task.

Death (死)

Where activity stops. Rather than moving outwardly, it gives the power to go deep into one thing, suiting research, technical and spiritual fields. In your luck, it signals slowing down and tidying up.

Tomb (墓)

Both a grave and a storehouse: the power to gather and keep, thrift and persistence. People with it tend not to show their inner feelings.

Severance (絶)

The old energy is cut off while the new is awaited. Much change, quick decisions and no fear of starting over. In your luck it marks a turning point where an ending and a beginning overlap.

Conception (胎)

New energy has just formed: potential, hope and plans that are still tender. Many ideas, which need time to be realised.

Nurture (養)

Growing in the womb — a time of being cared for and preparing. Gentle, and good at receiving help from others. It leads back into Birth.

A worked example

Our sample chart (庚午 year, 癸未 month, 辛巳 day, 癸巳 hour) has a 辛 Day Master. On the 辛 row of the table, the year branch 午 is Illness, the month branch 未 Decline, and the 巳 in the day and hour branches Death.

All four places are past the peak, so this chart reads as careful and deep rather than pushing to the front. With Death in the day branch — the seat of the self — the power to focus on one thing is a real strength. A chart like this depends more on good people and surroundings than on its own force, which ties in with chart strength.

The 60 day pillars by life stage

Each day pillar puts its Day Master in a fixed stage on its own day branch. Sorting all sixty with our engine, Birth, Coming of age, Peak, Illness, Tomb and Conception hold six pillars each, while Bath, Prosperity, Decline, Death, Severance and Nurture hold four. The split comes from yang and yin stems running the cycle in opposite directions, and from day pillars pairing yang with yang and yin with yin only. Tap a pillar to read it.

How strong is the Day Master in its birth month? 18,263 days counted

The first place saju looks for the Day Master's strength is the branch of the birth month. We calculated every day from 1960 to 2009 and counted the Day Master's stage in the month branch.

The twelve stages split almost evenly, about 8.3% each. Being born in a strong seat — Birth, Coming of age, Prosperity or Peak — happens to 33.5% of people, about one in three. The other two in three get less help from the month, but real chart strength also counts the support of Friends and Resources elsewhere; see chart strength.

FAQ

Is it bad to have Death, Tomb or Severance? No. The names sound heavy, but they are read as strengths: focus, storage and transition. The twelve stages are a supporting indicator and never decide good or bad on their own.

Is a chart full of Peaks a good one? It means strong energy, not necessarily good fortune. Abundant strength needs a stage to use it on and something to keep it in check.

How do I read the stages in my 10-year luck? Set your Day Master against the branch of each 10-year pillar to get that decade's stage. Prosperity and Peak decades add strength; Illness, Death and Severance decades suggest pacing yourself. See how to read luck pillars.

How this site calculates them: from the Birth branch of each Day Master, yang stems take (branch − Birth branch) and yin stems (Birth branch − branch), modulo 12, to pick one of the twelve stages — the "yin is born where yang dies" method. The stage of each of your four pillars is shown in a row of your chart table.
