Package: @node-jhora/prediction

The @node-jhora/prediction package handles time-based calculations, including dasha sequences, transit scanners, and Jaimini predictive tools.

⏳ Dasha Systems

Supports multiple predictive time-cycle systems.

1. Vimshottari Dasha

The most widely used system based on 120-year cycles.

• Precision: Calculates down to 5 levels (Maha, Antar, Pratyantar, Sookshma, Prana).
• Flexibility: Handles any duration and provides nested structure.

import { generateVimshottari } from '@node-jhora/prediction';

const dashas = generateVimshottari(birthDate, moonLon, 120);

2. Yogini Dasha

An 8-year recurring cycle system.

import { YoginiDasha } from '@node-jhora/prediction';
const periods = YoginiDasha.calculate(moonLon, birthDate, 80);

3. Narayana Dasha

A Rashi-based dasha (Varga Dasha) used for general life events.

• Directional Logic: Odd/Even sign logic for forward/reverse sequences.
• Exceptions: Handles Saturn and Ketu exceptions in the Lagna.

🛰️ Transit Engine

Scans for planetary movement over time, detecting house ingresses and aspects.

import { TransitEngine } from '@node-jhora/prediction';

const engine = new TransitEngine();
const events = await engine.findTransits(
    0, // Sun
    startDate,
    endDate
);

// Aspect detection using Newton-Raphson for high precision
const conjunct = await engine.findExactAspect(0, 4, 0 /* conjunction */, startDate); 

💎 Jaimini System

Core Jaimini astrological components.

1. Chara Karakas

Calculates the 7-karaka system based on planetary degrees within a rashi.

• AK (Atmakaraka): Highest degree.
• AmK (Amatyakaraka): Second highest.
• ... and so on.

2. Arudha Padas

Calculates the "Reflected Points" for houses.

• Handles the exception rules where if the lord is in the same house or 7th house, the Arudha jumps another 10/4 signs.

3. Chara Dasha

Sequence based on Jaimini's sign-based logic.

import { JaiminiDashas } from '@node-jhora/prediction';
const chara = JaiminiDashas.calculateCharaDasha(lagnaSign, planets);
