What is my Day Master? All 10 Day Masters in Saju and Chinese astrology
Your Day Master is the top character of your day pillar in Saju (Korean astrology) or BaZi. It's one of ten: Yang or Yin versions of Wood, Fire, Earth, Metal, and Water. It's read as your core self, and every other part of the chart is interpreted in relation to it. You find it from your birth date. Birth time only matters if you were born close to midnight.
The 10 Day Masters
| Day Master | Image | At their best | Blind spot | In relationships |
|---|---|---|---|---|
| 🌳 甲 Yang Wood (Gap) | A tall tree | Principled, steady, protects the people around them. | Won't bend, even when bending is smarter. | Loyal and consistent. Needs room to grow and hates being managed. |
| 🌳 乙 Yin Wood (Eul) | A vine or a flower | Adaptable, social, quietly persistent. | Goes around conflict instead of through it. | Attentive and reads the room. Wants reassurance more than they'll admit. |
| 🔥 丙 Yang Fire (Byeong) | The sun | Generous, energetic, lights up a room. | Overpromises and burns hot. | Warm and expressive. Feels ignored fast if the warmth isn't returned. |
| 🔥 丁 Yin Fire (Jeong) | A candle | Focused, perceptive, caring one-on-one. | Broods and remembers every slight. | Devoted to a few people. Notices everything you don't say. |
| ⛰️ 戊 Yang Earth (Mu) | A mountain | Reliable and calm under pressure. | Slow to change, hard to move once settled. | Shows love by showing up, not by saying it. |
| ⛰️ 己 Yin Earth (Gi) | Farm soil | Nurturing, practical, makes things grow. | Worries and absorbs other people's stress. | The caretaker. Quietly needs someone to take care of them back. |
| ⚔️ 庚 Yang Metal (Gyeong) | An axe or raw ore | Decisive, fair, cuts through noise. | Blunt enough to sound harsh. | Direct and loyal. Says it once and expects you to remember. |
| ⚔️ 辛 Yin Metal (Sin) | A jewel | Refined taste, precise, detail-aware. | Perfectionist and stung by criticism. | Wants to be appreciated specifically, not generally. |
| 🌊 壬 Yang Water (Im) | The ocean | Big-picture, curious, hard to rattle. | Restless and hard to pin down. | Needs freedom and commits on their own terms. |
| 🌊 癸 Yin Water (Gye) | Rain or dew | Intuitive, gentle, quietly strategic. | Hides feelings and withdraws instead of saying so. | Picks up on your mood before you do. Needs quiet time to recharge. |
How to find your Day Master
Your Day Master comes from where your birth date falls in a 60-day cycle that has run continuously for thousands of years. You can't work it out from the month or year. It needs a calendar calculation, which is what a Saju app does.
Midnight births: many Saju readers start the new day at 11 p.m. (the start of the Rat hour), so a late-night birth can shift your Day Master to the next day's. If you were born between 11 p.m. and midnight, check both.
Day Master and your element balance
The Day Master is the reference point. Traditional readers then ask what feeds it and what drains it. A Wood Day Master is fed by Water and drained by Fire (Wood burns to make Fire).
A Wood Day Master in a chart full of Water is read as a well-watered tree: resourceful, maybe overthinking. The same Day Master surrounded by Metal is a tree under pressure: disciplined, maybe stressed. That's why two people with the same Day Master can feel very different.
FAQ
Is the Day Master the same as my zodiac animal?
No. Your zodiac animal is the bottom character of your year pillar. Your Day Master is the top character of your day pillar. They come from different parts of the chart.
Which Day Master is the best?
None. Each has a default strength and a matching blind spot. Saju is more interested in balance and in how two people's Day Masters interact.
Yang vs Yin: what's the difference?
Yang versions are the big, outward form (a tree, the sun, a mountain). Yin versions are the smaller, inward form (a vine, a candle, soil). Yang tends to push; Yin tends to adapt.
