The Kuja Dosha Calculator is a web-based computational tool designed to analyze the geometric alignment of the planet Mars (Mangal) relative to three specific reference points: the Ascendant (Lagna), the Moon (Chandra), and Venus (Shukra). In Vedic astrology, specific angular relationships between Mars and these reference points generate a condition technically referred to as Kuja Dosha or Mangal Dosha.

This application functions as a logic engine that processes user-inputted zodiac coordinates to determine if Mars resides in a set of pre-defined “target houses.” The Kuja Dosha Calculator aggregates these findings into a composite score, applies algorithmic exceptions (Bhanga rules) based on planetary strength and aspects, and outputs a final classification of the Dosha status. The tool converts these astronomical positions into standardized metrics, including a severity index, a safety classification, and a binary presence/absence verification. The output includes a visual bar chart representing the ratio of risk versus safety potential based on a maximum theoretical score of 2.5.

Inputs Used by the Kuja Dosha Calculator

The Kuja Dosha Calculator requires specific astronomical data points to execute its algorithms. Each input field corresponds to a variable used directly in the conditional logic of the code.

1. Zodiac Coordinates

The core calculation relies on the relative positions of four specific celestial bodies. These inputs are integers ranging from 1 to 12, representing the twelve zodiac signs (Aries through Pisces).

  • Ascendant (Lagna): This defines the first house of the chart. The calculator uses this value to determine the house position of Mars relative to the self.
  • Moon Sign (Rashi): This defines the position of the Moon. The calculator computes the position of Mars relative to the Moon to identify “Chandra Mangal” conditions.
  • Venus Sign (Shukra): This defines the position of Venus. The code uses this to calculate Mars’ position relative to Venus, which contributes a weighted value to the final score.
  • Mars Sign (Mangal): This is the primary variable. The Kuja Dosha Calculator measures the distance of this sign from the Lagna, Moon, and Venus to determine house placement.

2. Calculation Standard

Because astrological traditions vary regarding which houses constitute a Dosha, the Kuja Dosha Calculator allows the selection of a specific rule set (array of integers):

  • South Indian Standard: Checks if Mars is in houses 2, 4, 7, 8, or 12.
  • North Indian Standard: Checks if Mars is in houses 1, 4, 7, 8, or 12.
  • Strict Inclusive: A comprehensive set that checks houses 1, 2, 4, 7, 8, and 12.

3. Planetary Modifiers

These boolean (true/false) inputs adjust the final calculated score:

  • Retrograde: Indicates if Mars implies apparent backward motion. In the code, checking this box alters the cancellation logic (reducing the power of a “Bhanga” exception) or adds a fractional penalty (0.25) to the score if no exception exists.
  • Combust: Indicates if Mars is too close to the Sun. If checked, the code subtracts 0.5 from the final score, mathematically representing a reduction in planetary effective strength.

4. Planetary Aspects

This dropdown allows the inclusion of external planetary influences that trigger “Bhanga” (cancellation) logic in the Kuja Dosha Calculator:

  • Jupiter Aspect/Conjunction: Triggers a “Level 2” (Full) cancellation in the code.
  • Moon Conjunction: Triggers a “Level 1” (Partial) cancellation.
  • Rahu/Ketu Conjunction: Used as a variable for potential future logic extensions (currently defined in the DOM).

How the Kuja Dosha Calculator Works

The execution of the Kuja Dosha Calculator follows a linear sequence of mathematical operations and conditional checks defined in the runCalculation function.

Step 1: House Normalization

First, the tool calculates the house number of Mars relative to each reference point (Lagna, Moon, Venus). The formula used for this modular arithmetic is:

House = (Mars Sign – Reference Sign + 1)

If the result is less than or equal to zero, 12 is added to the result to ensure a value between 1 and 12. This geometric calculation is performed three times:

  1. hLagna: Mars relative to Ascendant.
  2. hMoon: Mars relative to Moon.
  3. hVenus: Mars relative to Venus.

Step 2: Target Identification

The tool compares the calculated house numbers against the targetHouses array defined by the “Calculation Standard” input.

  • If hLagna is found in the target array, the variable dLagna is set to true.
  • If hMoon is found in the target array, the variable dMoon is set to true.
  • If hVenus is found in the target array, the variable dVenus is set to true.

Step 3: Raw Scoring

A raw numerical score is generated based on the identified targets. The code assigns specific weights to each reference point:

  • Lagna Impact: Adds 1.0 to the score.
  • Moon Impact: Adds 1.0 to the score.
  • Venus Impact: Adds 0.5 to the score.

The maximum possible raw score in the Kuja Dosha Calculator before modifiers is 2.5 (if Mars is in a target house relative to all three points).

Step 4: Exception Logic (Bhanga Analysis)

The code proceeds to verify if any “Bhanga” (Cancellation) rules apply. This logic assigns a “Power” value of 0 (None), 1 (Partial), or 2 (Full).

  • House-Sign Specifics (Power 2): The code checks specific combinations defined in classical texts. For example, if Mars is in the 2nd House relative to Lagna AND Mars is in Gemini or Virgo (Mercury signs), the code sets the exception to “Mer Sign in 2nd” and Power to 2. Similar checks exist for Mars in the 4th (Own Sign), 7th (Cancer/Capricorn), 8th (Jupiter Signs), and 12th (Venus Signs).
  • Jupiter Aspect (Power 2): If “Jupiter Aspect” is selected, Power is set to 2.
  • Own/Exaltation Sign (Power 1): If Mars is in Aries, Scorpio, or Capricorn (regardless of house), Power is set to 1.
  • Leo/Aquarius (Power 1): If Mars is in Leo or Aquarius, Power is set to 1.

Step 5: Final Calculation

The final score is derived by applying modifiers to the raw score:

  1. Retrograde Logic: If Mars is retrograde, a Power 2 exception is reduced to Power 1. If no exception exists, 0.25 is added to the raw score.
  2. Combust Logic: If Mars is combust, 0.5 is subtracted from the score.
  3. Cancellation Application:
    • If Power is 2, the Final Score becomes 0.
    • If Power is 1, the Final Score is divided by 2.

Results and Metrics Explained

The Kuja Dosha Calculator displays the output in a card-grid layout. The following defines what each metric mathematically represents based on the code.

Verdict Metrics

  • Dosha Status: A binary or ternary classification.
    • Absent: Raw score is 0.
    • Cancelled: Raw score was positive, but reduced to 0 by Bhanga logic.
    • Present: Final score remains greater than 0.
  • Safety: A classification of the risk level.
    • Safe: Final score is 0.
    • Conditional: Final score is between 0.1 and 0.5.
    • Caution: Final score is between 0.6 and 1.5.
    • Avoid: Final score is greater than 1.5.
  • Severity: Defines the intensity. Categories include “None”, “Mild” (score ≤ 0.5), “Moderate” (score ≤ 1.5), and “Severe” (score > 1.5).
  • Primary Trigger: Identifies the source of the score. If the Lagna contributes, it displays “Lagna”. If only the Moon contributes, it displays “Moon”. If multiple sources contribute to a high score, it displays “Multiple”.

Technical Data

  • Active Houses: A string code representing the detected positions (e.g., “L7” means Mars is in the 7th house from Lagna; “V12” means Mars is in the 12th house from Venus).
  • Weight Dist: Shows the contribution of each reference point (100 for Lagna/Moon, 50 for Venus).
  • Dosha Count: The integer count (0 to 3) of how many reference points (Lagna, Moon, Venus) triggered a target house match.
  • Rule Set: Displays the standard used for calculation (South, North, or Strict).

Remedies & Action

  • Bhanga Rule: The text description of the specific cancellation rule triggered in the code (e.g., “Guru Drishti” or “Mer Sign in 2nd”).
  • Cancel Strength: Indicates the magnitude of the reduction applied (Full, Partial, or None).
  • Match Req: A derived string indicating the strictness of matching required for a partner. High scores output “Strict,” while low scores output “Preferred” or “Optional.”

Interpreting the Calculation Output

The numerical output of the Kuja Dosha Calculator serves as a standardized index of astrological geometry.

  • Score 0 (Absent/Cancelled): The algorithm detected no geometric alignment of Mars in the specified target houses, or a “Bhanga” rule (like a Jupiter aspect) mathematically nullified the initial count.
  • Score 0.1 – 0.5 (Mild): Mars aligns with a target house relative only to Venus (weighted 0.5) or a major alignment was partially reduced by a Power 1 exception.
  • Score 0.6 – 1.5 (Moderate): Mars aligns with a target house relative to the Lagna or Moon (weighted 1.0), or a combination of Lagna/Moon plus Venus. This range indicates a standard Dosha presence without full cancellation.
  • Score > 1.5 (Severe): Mars aligns with target houses from multiple reference points simultaneously (e.g., 7th from Lagna AND 8th from Moon), resulting in a cumulative score exceeding the single-point threshold.

The visual chart renders these values on a scale of 0 to 2.5. The Dosha Risk bar represents the calculated final score as a percentage of 2.5. The Safe Potential bar represents the remainder.

Assumptions and Calculation Limits

The Kuja Dosha Calculator operates under specific constraints defined by the provided JavaScript code:

  1. Whole Sign Houses: The calculator assumes the “Whole Sign” house system. It does not calculate exact degrees or bhavas. If Mars is in Aries and Lagna is in Aries, it is considered exactly House 1, regardless of the degree within the sign.
  2. Hardcoded Weights: The weighting of reference points is fixed: Lagna (1.0), Moon (1.0), and Venus (0.5). These values are constants in the source code and cannot be altered by the user.
  3. Binary Bhanga: The cancellation logic is binary or semi-binary. A rule either applies fully (Power 2), partially (Power 1), or not at all. The code does not account for gradations of planetary strength (Shadbala) beyond these specific checks.
  4. Defined Standards: The definition of “North” and “South” standards is restricted to the specific house arrays defined in the code. Variations of these standards not programmed into the logic (e.g., excluding house 1 for South) are not supported.
  5. Combustion Value: The combust modifier applies a flat mathematical deduction (-0.5) and does not vary based on the proximity of Mars to the Sun in degrees.

Estimation Disclaimer

The results generated by the Kuja Dosha Calculator are mathematical estimates based on whole-sign zodiac logic and fixed algorithmic weights. These calculations provide a generalized assessment of planetary geometry and may differ from detailed manual calculations that utilize exact degrees or alternative house systems.
