| Day pillar | 癸亥 (gui hai) |
|---|---|
| Heavenly stem | 癸 (gui) |
| Earthly branch | 亥 (hai) |
| Day element | Water 水 (shui) |
| Polarity | Yin |
| Month pillar | 壬寅 (ren yin), governed by 立春 (lichun) |
Today's day pillar is 癸亥 (gui hai), a yin Water day in the sixty-day cycle. The month pillar is 壬寅 (ren yin), governed by the term 立春 (lichun).
亥 (hai), the twelfth earthly branch
亥 is the pig branch, the start of winter and the last hours before the day rolls over.
亥 closes the twelve. It is Water, yin by position, pig by animal. Its hours are 21:00 to 23:00, ending exactly where the 子 (zi) hour begins, and its month starts at 立冬 (lidong) in early November.
Its hidden stems are 壬 (ren, yang Water) and 甲 (jia, yang Wood), which is winter already carrying next spring's wood. That is the sexagenary system's habit in miniature: every ending has the next beginning stored inside it.
Because 癸 (gui) is the last stem and 亥 the last branch, 癸亥 (gui hai) is day sixty of the cycle. When the daily page shows it, the count restarts at 甲子 (jia zi) the following day.
