This is the New KP Ayanamsa (NKPA) Formula provided by Prof. K. Balachandran (KP & Astrology Year Book, 2003) to calculate Ayanamsa specifically at 5:30 AM IST on April 15 each year:
📐 Formula:
NKPA = B + [T * P + (T^2 * A)] / 3600
The answer lies in understanding the origin and use case of Gnati Karaka and how degrees are defined in each system:
📋 The New KP Ayanamsa Formula
KP Astrology is highly mathematical and event-timing oriented. One of its hallmarks is the use of a unique Ayanamsa to calculate precise planetary positions.
The New KP Ayanamsa (NKPA) Formula:
Given by Prof. K. Balachandran (KP Yearbook, 2003)
NKPA = B + [T * P + (T^2 * A)] / 3600
Where:
-
B
= Base Ayanamsa at 15 April 1900 = 22°22′30″ = 22.375 degrees
-
T
= Year - 1900 (e.g., 2000 => T = 100)
-
P
= 50.2388475 (Newcomb’s annual precession rate in arcseconds)
-
A
= 0.000111 (adjustment factor for increasing rate)
Purpose:
Comparison to Vedic Ayanamsa:
-
Vedic astrology commonly uses Lahiri (Chitrapaksha) or others like Raman.
-
KP uses its own formula for precision-based predictions.
-
The difference can affect planetary degrees and therefore timing.
What is Gnati Karaka?
In Jaimini Astrology (a Vedic system), Gnati Karaka is one of the 7 Karakas (significators) based on planetary degrees. It represents:
-
Enemies, obstacles, diseases, and karmic debts
-
Also relatives who challenge or oppose, or issues from past life
It is determined by ordering the planets based on their true longitude (degree within sign).
⚖️ KP vs Vedic: Which Degrees to Use for Gnati Karaka?
Gnati Karaka is a concept from Jaimini Astrology that identifies the planet responsible for enemies, obstacles, or karmic debts. It is determined by ranking the 7 planets (Sun to Saturn) by sidereal degree.
✉️ Important: Always use Vedic sidereal degrees (Lahiri or other chosen Ayanamsa) — NOT KP degrees — for calculating Gnati Karaka.
Why?
-
Gnati Karaka belongs to the Vedic system, which is sidereal.
-
KP degrees are adjusted for event-timing and not suited for Jaimini karaka logic.
1. Understand the System Origin
Correct Approach:
Use sidereal degrees with a Vedic Ayanamsa like:
-
Lahiri (Chitrapaksha) – most commonly used
-
Raman, Yukteshwar, or your preferred sidereal system
Then, order the 7 planets (Sun to Saturn) by absolute degrees, and assign Karakas:
Note: Rahu/Ketu not included in traditional 7 Karaka system.
💡 If you use KP Ayanamsa:
🔍 Conclusion: Gnati Karaka is not a KP concept, hence it should not be mixed with KP degree systems.
