I don’t know my birth time

Time basisClocks follow your time zone’s standard meridian, so the Sun at your birthplace can run minutes ahead of or behind the clock. Longitude correction fixes that offset; true solar time also adds the seasonal equation of time (±16 min). Rat-hour rule (23:00–00:59)Only matters if you were born between 23:00 and 23:59. Most modern practitioners use the early Rat-hour rule.

Why does birth time need correcting? ▾

Solar time, not clock time. In BaZi the hour pillar, and the day pillar near midnight, follow where the Sun actually was. Clock time is set for a whole time zone, so at your birthplace the Sun may cross the meridian earlier or later than clock noon. We use the longitude of your birthplace to correct for that, and can also add the equation of time (from −14 min in February to +16 min in November).

Daylight saving time is taken from your browser’s time zone database for the birth date, so summer-time births are converted to standard time automatically.

Whichever basis you pick, the “Pillars under each time basis” panel shows every combination side by side. If they differ, choose the one closest to the time on your birth certificate.

About BaZi (the Four Pillars of Destiny)

BaZi, called Saju in Korea, describes the moment of your birth as four pillars — year, month, day and hour — each made of a Heavenly Stem and an Earthly Branch. Those eight characters carry the five elements, and their balance is the starting point of every BaZi reading.

How your chart is calculated

The year begins at the Beginning of Spring, not on January 1 or Lunar New Year, and each month begins at a solar term. The day pillar follows an unbroken sixty-day cycle, and the hour pillar comes from your birth time converted to local solar time. Fate Hall also shows your Day Master (the stem of your day pillar), the Ten Gods, the twelve life stages, symbolic stars, your element balance and your Luck Pillars.

Reading your chart

Start with your Day Master — it stands for you — and look at which elements support it and which press on it. A chart heavy in one element and missing another is traditionally read as having a "balancing element" that helps. The other sections of Fate Hall build on this chart, so it is worth understanding first; the guide to Day Master strength shows exactly how Fate Hall weighs it, and the other guides are a good companion.
