Birth hour and leap month
Rat hour is split into early Rat at 00:00–00:59 and late Rat at 23:00–23:59. With half-month adjustment, the first fifteen days of a leap month stay with its month number and later days move to the next. Choose unadjusted to retain the lunar month number throughout.

The Life Palace names the chart’s central life-area reference. Body is a marker attached to one of the twelve palaces. The bureau is Water 2, Wood 3, Metal 4, Earth 5 or Fire 6 and supplies the initial decade-age count.
