Graha Maitri Calculator

Graha Maitri Calculator provides a precise evaluation of planetary friendship between partners. The system follows Ashta Koota principles, measures directional harmony, stability, emotional sensitivity, conflict risk, and overall marriage suitability in a clear, professional, and data focused format.

The Graha Maitri Calculator is a computational tool designed to evaluate the psychological and temperamental compatibility between two subjects based on Vedic astrological algorithms. This specific implementation utilizes the Graha Maitri Calculator logic to process the Moon Sign (Rashi) of a male subject (“Boy”) and a female subject (“Girl”). The primary function of the tool is to determine the relationship status—Friendly, Neutral, or Enemy—between the planetary lords governing the selected signs.

The calculator converts these qualitative planetary relationships into a quantitative score ranging from 0.0 to 5.0. This score represents the “Graha Maitri” (Planetary Friendship) component of the broader Ashta Koota matching system. By analyzing the 12 zodiac signs and their 7 distinct planetary rulers, the Graha Maitri Calculator generates a comprehensive report that includes the raw compatibility score, a risk assessment of planetary conflicts, and a percentile ranking against all 144 possible zodiac combinations.

Inputs Used by the Graha Maitri Calculator

The Graha Maitri Calculator requires two distinct data points to initiate the calculation matrix. These inputs serve as the keys for retrieving planetary lord data from the internal database.

• Boy’s Moon Sign (Janma Rashi): This input field requires the selection of the male subject’s zodiac sign based on the position of the Moon at birth. The calculator accepts one of 12 values: Aries (Mesh), Taurus (Vrishabh), Gemini (Mithun), Cancer (Karka), Leo (Simha), Virgo (Kanya), Libra (Tula), Scorpio (Vrishchik), Sagittarius (Dhanu), Capricorn (Makar), Aquarius (Kumbh), or Pisces (Meen). Internally, this input is mapped to a specific planetary lord (e.g., Aries maps to Mars, Leo maps to Sun).
• Girl’s Moon Sign (Janma Rashi): This input field functions identically to the Boy’s input but is applied to the female subject. It accepts the same 12 zodiac options. The code uses this selection to identify the ruling planet of the Girl’s sign. For example, if Taurus is selected, the Graha Maitri Calculator identifies “Venus” as the ruling planet for the calculation.

No other inputs, such as birth time, date, or geographic location, are utilized in this specific logic. The calculation is based strictly on the static relationship between the two selected Moon Signs.

How the Graha Maitri Calculator Works

The calculation process executes a specific sequence of logical operations defined in the JavaScript code. The Graha Maitri Calculator follows these steps:

1. Lord Identification: Upon clicking “Calculate Match,” the tool retrieves the ID (1–12) of the selected signs. It references a static object (rashis) to determine the planetary lord for each sign.
   • Mars: Rules Aries and Scorpio.
   • Venus: Rules Taurus and Libra.
   • Mercury: Rules Gemini and Virgo.
   • Moon: Rules Cancer.
   • Sun: Rules Leo.
   • Jupiter: Rules Sagittarius and Pisces.
   • Saturn: Rules Capricorn and Aquarius.
2. Relationship Lookup (The Matrix): The core logic relies on a 7×7 relationship matrix (relationships). The Graha Maitri Calculator determines how the Boy’s Lord views the Girl’s Lord (rB2G) and how the Girl’s Lord views the Boy’s Lord (rG2B). The matrix assigns one of three integer values to each directional relationship:
   • 1: Friend (Mitra)
   • 0: Neutral (Sama)
   • -1: Enemy (Shatru)
3. Point Calculation (Scoring Logic): The final score is derived by combining the two directional relationship values using the getPoints function. The scoring hierarchy is programmed as follows:
   • Same Lord: If both signs are ruled by the same planet, the score is 5.0.
   • Friend-Friend: If both lords view each other as Friends (1 and 1), the score is 5.0.
   • Friend-Neutral: If one view is Friend (1) and the other is Neutral (0), the score is 4.0.
   • Neutral-Neutral: If both lords view each other as Neutral (0 and 0), the score is 3.0.
   • Friend-Enemy: If one view is Friend (1) and the other is Enemy (-1), the score is 1.0.
   • Neutral-Enemy: If one view is Neutral (0) and the other is Enemy (-1), the score is 0.5.
   • Enemy-Enemy: If both lords view each other as Enemies (-1 and -1), the score is 0.0.
4. Percentile Calculation: The Graha Maitri Calculator runs a background simulation of all 144 possible combinations (12 x 12). It compares the current user result against this dataset to generate a percentile rank, indicating where the current match falls mathematically compared to the total population of combinations.

Results and Metrics Explained

The tool outputs several distinct metrics derived from the calculation logic described above.

• Graha Maitri Score: This is the primary output, displayed as a number between 0 and 5. It represents the total compatibility points awarded based on the planetary friendship matrix.
• Directional Influence: This metric breaks down the relationship into two vectors: “Boy → Girl” and “Girl → Boy.” It visualizes whether the relationship is Friend, Neutral, or Enemy from each perspective.
  • Symmetric: Indicates both planets hold the same view of each other (e.g., both Neutral).
  • Asymmetric: Indicates differing views (e.g., one is Friendly, the other is Neutral).
• Conflict Scanner: This metric counts the number of “Enemy” (-1) relationships found in the lookup.
  • 0: No planetary enmity.
  • 1: One planet views the other as an enemy.
  • 2: Mutual planetary enmity.
• Emotional Sync (Moon/Venus Risk): The code performs a specific check for the planets Moon and Venus. If either of these planets is the ruler of a selected sign and is involved in an “Enemy” relationship, the Graha Maitri Calculator flags the result as “Afflicted” or “Mismatch.” If neither acts as an enemy, it is labeled “Stable.”
• Marriage Suitability: This is a binary threshold metric.
  • Suitable: Score is greater than or equal to 3.0.
  • Unsuitable: Score is less than 3.0.
• Dosha Analysis: The code defines a “Dosha” condition specifically when the score drops below 1.0.
  • Status Clean: Score ≥ 1.0.
  • Ritual Reqd: Score < 1.0 (indicating 0.5 or 0.0 points).
• Planetary Dominance: This metric identifies which subject’s planetary ruler holds the more favorable view.
  • Mutual: Both views are equal.
  • Boy/Girl: One subject’s lord views the other as a Friend, while the reciprocal view is Neutral or Enemy.

Interpreting the Calculation Output

The numeric values generated by the Graha Maitri Calculator represent specific mathematical conditions defined in the code’s logic.

• Score of 5.0: This value indicates a state of “Mitra” (Friendship) or identity. It occurs mathematically only when the planetary lords are identical (e.g., Aries and Scorpio, both ruled by Mars) or mutually friendly (e.g., Sun and Jupiter).
• Score of 4.0: This value represents a “Sama-Mitra” combination. The code generates this when one planet is friendly and the other is neutral.
• Score of 3.0: This serves as the mathematical midpoint. It results from a “Sama-Sama” relationship where both planetary lords view each other as neutral. This is the minimum threshold the code uses to label a match as “Suitable.”
• Score of 0.0 to 1.0: These lower values indicate the presence of “Shatru” (Enemy) relationships in the matrix. A score of 1.0 means a Friend-Enemy dynamic, 0.5 means Neutral-Enemy, and 0.0 means Mutual Enemy. The Graha Maitri Calculator flags these ranges as High Risk or Poor Match.
• Percentile Score: A higher percentile (e.g., >80%) indicates that the current score is mathematically higher than 80% of all other possible Moon Sign combinations. A lower percentile indicates the score is common or below average relative to the 144 unique pairs.

Assumptions and Calculation Limits

The Graha Maitri Calculator operates under specific constraints and fixed parameters defined within the source code:

1. Parashara System: The relationship matrix (Friends/Neutral/Enemies) is hardcoded based on the classical Parashara light system. It does not account for alternative systems like Jaimini.
2. Natural Friendship Only: The code calculates Naisargika Maitri (Natural Friendship). It assumes Tatkalika Maitri (Temporary Friendship based on planetary position at birth) is excluded. The tool explicitly labels this as a “Static Calculation.”
3. Sign-Based Only: The calculation relies entirely on Rashi (Moon Sign). It does not factor in Nakshatras (Constellations) or Padas (Quarters).
4. Binary Gender Inputs: The inputs are labeled specifically as “Boy” and “Girl,” and the logic assumes a comparison between these two distinct entities.
5. Fixed Thresholds: The determination of “Suitable” (Score ≥ 3) and “Average” (Score ≥ 1) is based on fixed integer comparisons in the code and does not adjust for contextual nuances.
