A BaZi chart pairs one Heavenly Stem with one Earthly Branch for the year, month, day, and hour of birth. The stem of the Day Pillar becomes the Day Master, the reference point for reading the rest of the chart.
Fixed demo: male, May 15, 1990, noon, Beijing. It is an example chart, not a visitor's personal result.
The familiar animal sign comes from the Earthly Branch of the Year Pillar. A complete Four Pillars chart also includes the year stem plus the month, day, and hour pairs, so people born in the same animal year can still have very different charts.
The Day Master is not the whole personality. It provides the center from which the Five Elements and Ten God relationships are compared. Season, supporting elements, and the other seven characters change how that reference point is interpreted.
BaZi divides a day into twelve two-hour periods. This calculator resolves the date-specific time-zone and daylight-saving offset, then applies birthplace longitude and the equation of time before assigning the Hour Pillar.

It turns your birth date, time, and place into the Four Pillars chart: year, month, day, and hour pillars shown as heavenly stems and earthly branches.
Exact birth time gives the most complete hour pillar. If you only know the approximate period, you can still choose the matching two-hour Chinese time period.
Yes. When you enter an exact time and select a city, the calculator resolves the historical time-zone and daylight-saving offset, then applies longitude and the date-specific equation of time before calculating the Hour Pillar.
The free reading gives your core chart, Day Master, zodiac pillars, element balance, and a preview of the interpretation. No account or email is required before you see it.
The Day Master is the heavenly stem of your Day Pillar. It is the reference point used to read the other stems, branches, elements, and Ten God relationships in the chart.
Birthplace supplies the longitude and historical time-zone rules used to convert civil clock time into apparent solar time. That correction can change the Hour Pillar near a two-hour boundary.
Calculators can use different solar-term instants, solar-time corrections, daylight-saving histories, or midnight conventions. These differences matter most near a boundary.
