About the Four Pillars & Day Master
Four Pillars of Destiny (BaZi) reads a birth moment as four stem–branch pillars: year, month, day and hour. The day pillar’s stem — the Day Master — is taken as the self. The day pillar here is computed exactly from the unbroken 60-day sexagenary cycle.
※ The year, month and day pillars are fixed by your birth date — the year/month boundaries (Beginning of Spring and the solar-term nodes) are computed precisely from solar longitude, and the day pillar from the unbroken sexagenary cycle. The hour pillar, needed for a full chart, requires your birth time and is not shown. The stem images (a great tree, the sun…) are traditional BaZi symbols — astrology, not a scientific claim.
