Concise Manual on Planetary Motion with Commentary

245 Following that—on the New Moon day original: "Amavasya", the Swati lunar mansion original: "Nakshatra" lasted for 26 ghatis and 23 palas approx. 10 hours and 33 minutes after sunrise, the Saubhagya yoga lasted for 52 ghatis and 14 palas, in the Chaturanghrika Karana astrological divisions of the day, on Friday. The Sun’s position in the Libra sign was 27 degrees, 56 minutes, and 17 seconds. The elapsed time from sunrise was 4 ghatis and 22 palas. The Bhayaat time elapsed in the current Nakshatra was 44:21 and the Bhabhoga total duration of the Nakshatra was 66:32. The length of the day was 26 ghatis and 56 palas. At this auspicious moment, during the rising of the Scorpio ascendant Lagna, at a fortunate hour, by the grace of the personal deity, the Brahmins, and the Guru, a second son was born to Shri Yogeshwar Sharma, bringing joy to the Abhaya family. According to the Shatapada chakra system, the birth occurred in the third quarter charana of the Swati mansion; therefore, the child was given the famous name 'Shri Rohit', starting with the syllable 'Ro' corresponding to that quarter. May there be fortune. May there be auspiciousness. May he live a long life.

Example—

We must calculate the Ahargana Ahargana: the total number of elapsed days from a fixed epoch to a target date for the New Moon of the dark fortnight of the month of Karttika, Friday, in the Shaka year 1758 approx. 1836 CE. Following the previously stated method: 1758 - 1442 = 316. Therefore, 316 ÷ 19 = a quotient of 27 and a remainder of 9. Here, 27 is the number of cycles Chakra. 12 × 9 = 108. From the first day of Chaitra to the New Moon of Ashvina, 6 lunar months have passed. Thus, 108 + 6 = 114. This is placed in two positions: 114 and 114. The cycle count is 27. Therefore, (27 × 2) + 10 + 114 = 54 + 10 + 114 = 178. 178 ÷ 33 = 6, which are the intercalary months Adhimasa. Thus, 114 + 6 = 120 months have passed. 120 × 30 = 3600. From the first day of Ashvina to the 14th day of the dark fortnight of Karttika, 29 lunar days Tithis have passed. Thus, 3600 + 29 = 3629 lunar days. Therefore, 37 ÷ 6 = quotient 6, remainder 1. So, 3629 + 6 = 3635. Since 3635 ÷ 64 = quotient 56, remainder 51. Because the remainder 51 is more than half, the quotient is increased by 1; therefore, 57 are the omitted days Kshayah. Thus, 3635 - 57 = 3578, which is the Ahargana (total day count).

Determining the weekday from the Ahargana— Cycle = 27. Therefore, 27 × 5 = 135. The Ahargana = 3578. Thus, 3578 + 135 = 3713. 3713 ÷ 7 = quotient 530, remainder 4. Counting from Monday, the 4th day is Thursday (elapsed), and the current day is Friday.

If the desired weekday is not reached when calculating from the Ahargana, one should add or subtract one (as appropriate). Furthermore, if an intercalary month occurred in a month prior to the one being calculated but does not appear in the calculation, one should add 1 to the obtained intercalary months. If an intercalary month is expected after the desired month but appears earlier in the calculation, one should subtract 1. See the Vishwanathi commentary for examples.

Now, the Constant Values (Dhruvak) of the Planets—

Zero, one, three, zero, five, zero, and five for the Sun; zero, three, three, six, four, and eleven for the Moon; These are mnemonic numbers representing astronomical constants in the Katapayadi or similar notation
Two for the Moon's sign, then for the planets: two, five, four are said for the Moon's ascending node.
Seven, two, zero, five for Mars; five, two, three, two for Mercury;
For the center, four, three, zero; for Jupiter, zero, six, two, eight, one;
For the fast center of Venus, one, thirteen, two; starting from the signs, then for Saturn:
Seven, one, five, one, two, four—these are now the epoch constants (Kshepakas) being told.? Digitized by Google
