What is a Day Master?
A BaZi chart has four pillars (year, month, day, hour), each pairing a stem with a branch. The day stem is your Day Master — the core element that is 'you', and the starting point of the whole reading. Two people born in the same zodiac year can have entirely different Day Masters: the zodiac describes the year's weather; the Day Master describes you.
