The calculation for the True Mercury original: "Spashta Budha"; the mathematically corrected position of the planet was completed. Before this, one quarter of the constellation Purva Bhadrapada, four quarters of Uttara Bhadrapada, and two quarters of Revati—totaling seven quarters—were passed, resulting in 23 degrees and 20 minutes. Now, adding the 0 degrees, 33 minutes, and 36 seconds calculated by proportion for the third quarter of Revati, the True position becomes 23 degrees, 53 minutes, and 36 seconds. Since Mercury is in the sign of Pisces, it is appropriate to write 11 in the place of the Zodiac Sign In Vedic astrology, Pisces is the 12th sign, represented by the number 11 as it follows 11 completed signs. Thus, 11s 23° 53' 36" becomes the instantaneous True position of Mercury. One should understand the method for others in this same way. These two methods have been described in a simplified manner for the sake of ease. While they suffice for general work, precise calculations are performed using astronomical tables Karana-sarani; simplified astronomical manuals such as Grahalaghava, Mahadevi, Makaranda, and Ramavinoda. Even more precise results come from the Siddhantas comprehensive theoretical treatises on astronomy. The method for calculating the True Moon is similar, as follows:

Bhujangaprayatam Meter A poetic meter consisting of four 'Yagana' feet—Multiply the elapsed portion of the constellation by sixty and divide by the total duration. Multiply the number of elapsed constellations by sixty and add the previous result. Multiply this by two and divide by nine to find the degrees. To find the daily motion, divide 48,800 by the total duration of the constellation. || 19 ||

On the day the True Moon is to be calculated, one must determine the elapsed time Bhukta, the remaining time Bhogya, and the total duration Sarva Bhogya/Bhabhoga of the constellation Nakshatra at the desired time. The method is this: the number of ghatis and palas traditional units of time; 1 ghati = 24 minutes the constellation has passed until the desired time is called the 'elapsed'. What remains is the 'to be passed', and the sum of both is the 'total duration'. Multiply the elapsed time by 60 and divide by the total duration; the result is the elapsed portion in a 60-unit scale. Count the number of constellations passed from Ashwini onwards, multiply that number by 60, and add the ghatis obtained from the current constellation's duration. This gives the total elapsed ghatis. Then, multiply by 2 and divide by 9; the quotient is the degrees. Multiply the remainder by 60 and divide by 9 to get the minutes Kala. Again, multiply the remainder by 60 and divide by 9 to get the seconds Vikala. If the degrees exceed 30, divide by 30; the quotient is the Zodiac Sign and the remainder is the degrees. This completes the calculation of the True Moon.

Example: Year 1943 of the Vikram Era, month of Vaishakha, dark fortnight, 12th day, Saturday. At the desired time of 13 ghatis and 54 palas, the elapsed time of the constellation Uttara Bhadrapada is 54 ghatis and 13 palas...
