Damo Yi Zhang Jing Knowledge Base · 達摩一掌經知識庫

Damo Yi Zhang Jing (達摩一掌經, "Bodhidharma’s Palm Sutra") is a traditional Chinese date-of-birth divination. Using the lunar birth date, the four pillars — year, month, day and hour — are counted in turn onto the twelve earthly branches laid out on the palm, each branch carrying one of twelve palm stars. The stars the four pillars land on describe a person’s innate foundation, character and fortune across life.

Navigate

• The Twelve Palm Stars — 掌中十二星
• The Four Pillars — 四柱
• The Six Realms — 六道根性 (past-life nature)
• The Five Elements — 四柱五行 (element generation & restriction)
• Four-pillar Interactions — 四柱交互 (clash, harmony, punishment, harm, destruction & named patterns)
• Schools & Conventions — 流派 (late-Zi & leap-month choices)
• Annual Fortune — 流年 (time dimension)
• Decade Luck — 大限 (ten-year periods)
• Monthly Palm Star — 本月掌中星／流月 (the step between year and day)

• Daily Palm Star — 今日掌中星／流日 (the daily layer, and why it is not classical)

How a reading is cast

1. Convert the Gregorian birth date to the Chinese lunar date.
2. Year: place the year pillar on the branch of the birth year.
3. Month: from the year branch as the 1st lunar month, count forward to the birth month.
4. Day: from the month branch as the 1st day, count forward to the lunar birth day.
5. Hour: from the day branch as the Zi (子) hour, count forward to the birth two-hour branch.
6. Read the palm star each of the four pillars lands on — the Year pillar (根基) first.

Advanced reading

• Six-realm nature (六道根性): the Year pillar star points to one of the six realms one is said to have come from, colouring innate character.
• Four-pillar interaction (四柱交互): the earthly branches of the four pillars can clash (沖), harmonise (合), form a trine (三合), punish (刑), harm (害) or break (破) one another — and one pair can carry several of these at once. A palm star repeated across pillars is amplified, and certain star combinations form named patterns — together these show how the areas of life pull on or reinforce each other.
• Five-element generation & restriction (四柱五行生剋): each pillar carries one of the five elements; their balance (which is abundant or missing) and how they generate (相生) or restrict (相剋) between adjacent pillars adds a further layer.
• Schools & conventions (流派): schools differ on the late-Zi day boundary and leap-month assignment — see schools; the tool lets you choose.
• Annual fortune / time dimension (流年): each year’s branch fixes a palm star, read against all four natal pillars to say which part of life the year lands on — see annual fortune.
• Decade luck (大限): ten-year periods walked around the twelve palaces. Schools disagree on where they start, so the tool offers two documented methods — see decade luck.

For entertainment and cultural reference. The Palm Sutra is interpretive and schools differ on a few placement details; this base reflects a common mainstream method.
