Sukuyo twelve palaces and four mansion feet
Sukuyo twelve palaces assign four feet to each mansion and nine to each palace; a date-only birth result cannot identify a person’s exact foot.
Overview
The four-foot and nine-foot boundaries explain possible spans. They do not select a personal degree from a date-only result.
At a glance
- Mansion feet
- 27 × 4 = 108
- Palace feet
- 12 × 9 = 108
- Exact personal foot
- Not resolved by the date-only label
Why some mansions span two palaces
Four-foot mansion boundaries and nine-foot palace boundaries do not always coincide.
A mansion can therefore have feet assigned to more than one palace without there being two different mansion identities.
A source example
The 羊 palace contains 婁 four feet, 胃 four feet and 昴 one foot. The remaining three feet of 昴 belong to the next palace.
This is a reference map, not proof of a particular person’s Moon degree.
Possible does not mean exact
The current product preserves possible signs and leaves exactPada unresolved.
Do not select one foot because it sounds more accurate or fits a preferred personality description.
What exact resolution would need
A degree-based assignment requires a declared zodiac origin, longitude calculation and suitable birth instant.
Those settings belong to a different precision level from the month/day lookup.
Do not substitute a Sun sign
A Western Sun-sign date range does not resolve this mansion’s personal foot.
Compare the bodies, coordinate systems and inputs before linking similarly named signs across traditions.
Check the 108-foot accounting
Confirm that 27 mansions × 4 feet and 12 palaces × 9 feet both total 108. Then trace a boundary example such as 昴, whose feet span two palaces in the source map.
The accounting can verify the reference grid while exactPada remains unresolved for a date-only personal result.
