Understanding Longevity Calculation in Vedic Astrology

The method to calculate the longevity (Ayu) of an individual involves determining whether the life span is extended, moderate, or concise based on planetary positions.

Key Factors in Longevity Calculation

  • Natal Ascendant and 8th Lord:
    • If the Lord of the natal ascendant and the 8th Lord occupy movable and dual signs respectively, it indicates a concise life span (Alpayu yoga).
    • If the Hora Ascendant is in a movable sign and the natal ascendant is in a fixed sign, it indicates a moderate life span.

Yoga Karakas

Planets or ascendants contributing to the life span determination are known as yoga karakas. Their degrees and kalas are summed and divided by the number of yoga karakas.

Calculation Steps

  1. Sum the Degrees and Kalas of the yoga karakas.
  2. Divide the total by the number of yoga karakas.
  3. Multiply the quotient by a factor depending on the life span category:
    • 40 for extended
    • 36 for moderate
    • 32 for concise
  4. Divide the product by 30 to get years and months.
  5. Subtract from the base life span (e.g., 72 years for moderate life span) to get the clear longevity (Spashta Ayu).

Special Rule for Saturn

A special rule applies for Saturn:

  • If Saturn is a yoga karaka, the longevity class declines (extended to moderate, moderate to concise, concise to very concise), except when:
    • Saturn is in exaltation,
    • in its own sign, or
    • conjunct/aspected by a challenging planet, in which case there is no change.
