Computation method

Method type: decision-table

Grade each sunrise Panchangam limb with maintained rule sets, count only limbs graded shuddha, and map the count from zero through five to a verdict label.

Process

1. Grade Tithi ashuddha only for Rikta 4th, 9th, and 14th classes.
2. Grade Vaara from the four auspicious and three inauspicious weekday sets.
3. Grade Nakshatra by Laghu/Mridu/Dhruva/Chara, Tikshna/Ugra, or Mishra category.
4. Grade Yoga from auspicious, hard-avoid, partial-dosha, or neutral sets and Karana from movable versus Vishti/fixed sets.
5. Count quality=shuddha and index the six verdict labels.

Worked example

Hyderabad sunrise, 2026-06-11, Drik Ganita

Inputs

• Krishna Ekadashi
• Guruvaram
• Revati
• Shobhana
• Bava

Calculation

1. Each of the five values maps to shuddha in its respective table.
2. Shuddha count = 5.

Result

• Verdict: Sarva Shuddha
• Count: 5 of 5

Method notes

• Mixed limbs do not increment the count; the result is a general day-level screen, not a personal Muhurtam verdict.
