Frequently Asked Questions
What is a Day Master in BaZi?
The Day Master is the Heavenly Stem of your Day of Birth. In Chinese Astrology (BaZi or Four Pillars of Destiny), it is the most critical reference point. It represents your "True Self"—your core personality, innate strengths, and weaknesses. All other elements in your birth chart are analyzed based on their relationship to your Day Master.
How is the Day Master calculated?
The Day Master is calculated using a complex algorithm that converts your Gregorian birth date and exact time into the traditional Chinese sexagenary (60 Jiazi) calendar. Our calculator also rectifies your birth time to True Solar Time to ensure maximum astrological accuracy.
What are Favorable Elements?
Based on whether your Day Master is considered "Strong" or "Weak" when born in a specific season (Month Pillar), Chinese astrology prescribes "Favorable Elements" to balance your chart. Surrounding yourself with your favorable elements (through colors, careers, or partners) brings harmony and success.
