What Is the Day Master?
In Bazi (Four Pillars of Destiny), your Day Master (日主, Ri Zhu) is the Heavenly Stem of your Day Pillar. It's the single most important element in your chart because everything else is analyzed relative to it.
Think of your Day Master as the main character of your life story. The other seven characters in your chart are the supporting cast — some help you, some challenge you, some are neutral.
How to Find Your Day Master
Your Day Master is determined by your birth day (not your zodiac year). Each day in the Chinese calendar has a Heavenly Stem — one of ten elements:
| Stem | Element | Yin/Yang | Animal Association | |---|---|---|---| | 甲 (Jia) | Wood | Yang | Tiger | | 乙 (Yi) | Wood | Yin | Rabbit | | 丙 (Bing) | Fire | Yang | Dragon | | 丁 (Ding) | Fire | Yin | Snake | | 戊 (Wu) | Earth | Yang | Horse | | 己 (Ji) | Earth | Yin | Sheep | | 庚 (Geng) | Metal | Yang | Monkey | | 辛 (Xin) | Metal | Yin | Rooster | | 壬 (Ren) | Water | Yang | Dog | | 癸 (Gui) | Water | Yin | Pig |
