The thirtieth-part division Trishansha original: "triṃśāṃśakam" of 4 resulted in 32 Pala-units Palatmaka A Pala is a unit of time equal to 24 seconds.. The instantaneous position Taatkalika of the Sun Surya, having processed the desired result Ishtaphalam of 58 / 58, and being multiplied and added to the desired Palas, the Sun is calculated as: 2 / 21 / 48 / 58.
The tropical position Sayana The longitude including the correction for the precession of the equinoxes. is 2 / 28 / 5 / 58. Taking the 14 desired Pala-units and multiplying by the thirtieth-part (12), because the remaining time Bhogyam The portion of a zodiac sign yet to rise. is short original: "bhogyantolpakāla", and so forth...
Due to the short duration from the Ascendant Lagna, the remaining portion is 2 / 43. The desired 54 Pala-units represent the small remaining duration in Palas, which is multiplied by three to get 12.
This is divided by the rising measure of Gemini Mithuna-mana The specific time duration it takes for the sign of Gemini to rise above the horizon at a particular latitude., which is 299, resulting in 4 / 146. Adding this to the Sun Ravi, the position is 2 / 23 / 5 / 58.
The precession of the equinoxes Ayanamsha is 2 / 22. Subtracting this [from the tropical position] results in 2 / 1 / 14 / 58, which is the purified Ascendant Shuddha Lagna.
If, by that day's time-measure, the tropical Sun is 2 / 28 / 5 / 58, the tropical Ascendant Sayana Lagna and the difference between the two is 4 / 54 / 46 minutes.
