Beijing civil time and four-pillar boundaries

Year, month, day, and hour pillars are computed after converting the civil instant to UTC+8. This is an introductory layout, not a full luck-cycle reading.

Without a birth hour, the hour pillar stays unknown. Day-boundary edge cases can mark candidates instead of forcing one answer.

Traditional stem and branch names are cultural labels. They are not medical, financial, or harm predictions. Independent reference charts for this sect-2 Beijing method have passed the local verification gate.

This product states its convention so a chart can be reproduced. A known birth instant is converted to Beijing civil time before the library calculates the pillars. Sect 2 uses the documented day-boundary treatment. This is not a true-solar-time correction, and a chart made with a different day boundary or location correction may disagree near an edge. Comparing chart labels without comparing methods can therefore be misleading.

An unknown time leaves the hour pillar absent and retains any uncertainty returned for the date. Do not fill a missing pillar from a personality description. Stems, branches, five phases, and ten-god relations are traditional names attached to saved calculations. An element count is not a nutritional measure, and a ten-god label is not a judgment about moral worth. The introductory chart does not compute full luck cycles or authorize health, investment, or marriage decisions.
