Schools & Conventions · 流派
The Palm Sutra is interpretive, and schools differ — most concretely in how a birth date is turned into the four pillars. Two choices actually change the chart: the late-Zi day boundary and leap-month assignment. The reading tool exposes both, defaulting to the common usage.
- 子時換日 (Zi-hour day boundary) — The Palm Sutra fixes the Day pillar from the lunar day.
- 閏月歸月 (Leap-month assignment) — A leap month sits between a month and the next; schools differ on which month a leap-month birth is charted under.
- 大限起法 (Decade-luck start) — Classical Palm Sutra texts read the four pillars; decade luck (大限) is a later addition and schools do not agree on it — whether to start from the Year or the Hour pillar, and whether direction depends on sex.
- 流月／流日起法 (Monthly & daily star method) — The Palm Sutra has a common method for the year (the year’s branch fixes the year star); for the month and the day it has none.
