Longevity Forecast Methodology
The Longevity Forecast Engine translates classical Sanskrit mathematical canons into an auditable computational engine. Instead of speculative generalities, this tool evaluates the core principles of Jaimini and Parashari systems, calculating 12 distinct classical Ayur Dasa timing systems to identify overlapping critical periods across the native's lifespan.
By feeding exact geographic birth coordinates and birth times into high-precision astronomical algorithms (Swiss Ephemeris), the engine generates divisional charts, calculates active planetary Dasas, and assesses vital life energy indicators.
The engine evaluates three primary pairs of indicators to place the native in a baseline longevity category:
- Lagna Lord and the 8th Lord: Evaluates the strengths of the lord of self (Lagna) and the lord of longevity/death (8th house).
- Lagna and the Moon: Compares the physical coordinates of the self and the mental/vital life force represented by the Moon.
- Lagna and the Hora Lagna: Integrates Hora Lagna (financial and vital energy pivot) to check structural support.
Based on these combinations, the native is categorized into:
- Alpayu (Short Life): 0 to 32 Years
- Madhyayu (Middle Life): 32 to 64 Years
- Dirghayu (Long Life): 64 to 96+ Years
The baseline category is not fixed. The engine applies mathematical adjustments based on planetary configurations:
- Kakshya Vriddhi (Longevity Increase): Triggered when benefics occupy the Lagna, the 8th house, or aspect active signs. Jupiter or Venus occupying crucial quadrants increases vitality.
- Kakshya Hrasa (Longevity Decrease): Occurs when malefics (Mars, Saturn, Rahu, Ketu) occupy the 8th house or surround the Lagna lord.
Rather than relying on a single dasa cycle, the longevity engine computes 12 independent classical timing systems simultaneously: Shoola, Brahma, Maheshwara, Atmanadi, Sthira, Darpana, Atmano Bhavapamsa, Jaya Bhavapa, Atmamsa Bhavapamsa, Chara Paryaya, Varnada, and Hora Dasa.
Each system independently identifies Maraka (death-inflicting) signs and vulnerable Varshacharya years. Where multiple independent Dasa systems converge on the same decade or year, the system flags a high-vulnerability transition window.
This results in the Longevity Timeline Graph (Ages 1 - 108) and the Decadal Convergence Distribution, providing an auditable, multi-cycle consensus of planetary stress.
* Base Longevity Category: Indicates the primary classical window calculated from your natal chart. * Planetary Strengths (Shadbala & Bhavabala): High values indicate stronger resistance to negative transits. * Longevity Curve: Shows the probability of passing through critical planetary periods. Declines in the graph correspond to Dasa transitions of Maraka (death-inflicting) signs.
