Named Shani transit conditions

gochara.named-shani-conditions

Saturn's house from Janma Rashi is labeled as Sade Sati, Ashtama Shani, or Ardhastama Shani where applicable.

Assurance

Independently source-supported	Partial support only; read the provenance note and limitations before generalizing.

Computation method

Method type: decision-table

Count Saturn's current sign inclusively from Janma Rashi and label only houses 12, 1, 2, 8, and 4.

Process

1. Convert Janma Rashi and Shani Rashi to canonical indices.
2. Compute the inclusive wrapped house number.
3. Map 12/1/2 to rising/peak/setting Sade Sati, 8 to Ashtama Shani, and 4 to Ardhastama Shani.
4. Return an empty list for every other house.

Formulae

Transit house

h = ((index(transit)-index(janma)) mod 12)+1

• h: inclusive house from Janma Rashi

Worked example

Shani in Meena from Mesha Janma Rashi

Inputs

• Janma Rashi: Mesha
• Shani Rashi: Meena

Calculation

1. ((11 - 0) mod 12) + 1 = 12.
2. House 12 maps to the rising phase label.

Result

• Sade Sati (rising phase)

Method notes

• The labels summarize a Moon-sign transit convention; they do not infer natal placements, Dasha, aspects, or individualized outcomes.

Locator: Phaladeepika, Adhyaya XXVI, sloka 1 for Janma Chandra as the transit reference and slokas 22-23 (printed pp. 295-296) for Shani's effects in houses 1, 2, 4, 8 and 12

Scope: Verifies that these five Shani positions are reckoned from the natal Moon and have adverse classical transit effects. It does not verify grouping houses 12, 1 and 2 under the vernacular name Sade Sati; the names Ashtama Shani and Ardhastama Shani; the rising, peak and setting phase labels; or the deterministic advice sentences. Those remain configured conventional or project-interpreted presentation layers.

Limitations

• Names and phase labels are conventional presentation and not a complete natal transit judgment.
