The 10 BaZi Day Masters
Your BaZi 'Day Master' (日主, also 日元) is the Heavenly Stem of the day you were born — the centerpiece of the whole chart, the part that represents you. The ten stems (甲乙丙丁戊己庚辛壬癸) are each a pairing of one of the Five Elements with yin or yang — the personality archetypes of Eastern astrology. Knowing your Day Master is the first step to reading a BaZi chart.

The Day Master is who you are — the Ten Gods (十神) are how everyone and everything else in the chart relates to you: wealth, authority, output, resources, and peers. Read the Ten Gods and you read the whole chart.
Frequently Asked Questions
What does the BaZi Day Master mean?
The Day Master (日元) is the Heavenly Stem of your birth day — it represents you, and it is the heart of the chart. The other seven characters are all read relative to it: what generates it (Seal), what controls it (Officer/Killings), what it generates (Output), and what it controls (Wealth). Reading BaZi always starts from the Day Master.
How many Day Masters are there?
There are ten — the ten Heavenly Stems: Jiǎ, Yǐ, Bǐng, Dīng, Wù, Jǐ, Gēng, Xīn, Rén, Guǐ (甲乙丙丁戊己庚辛壬癸). Each of the Five Elements (Wood, Fire, Earth, Metal, Water) is shared by two stems, one yang and one yin — e.g. Jiǎ (甲) is Yang Wood and Yǐ (乙) is Yin Wood.
Is a weak Day Master bad?
No. A Day Master's 'strength' only describes how much support it gets in the chart — it is not good or bad in itself. A strong Day Master and a weak one each have their own favorable structure. What matters is whether the whole chart is balanced and the 'useful god' (用神) is well-placed, not strength alone.
