The sum with the birth weekday and other factors 6;53;0 results in the weekday of the year's commencement 4;8;58. In this system, 4 represents Wednesday, the fourth day of the week starting from Sunday. || 10 ||

Now, the Calculation of the Lunar Day (Tithi)

The number of elapsed years multiplied by 343 original: "gunavedarama," a numerical code where guna=3, veda=4, rama=3 and divided by 31 original: "kurama," where ku=1, rama=3 gives the days and fractions. This, combined with the days elapsed since the start of the month at birth and divided by 30 original: "kharama," where kha=0, rama=3, yields the remaining lunar days for the current year. || 11 ||

Regarding the calculation of the lunar day: "The number of elapsed years..."—For example, the elapsed years 59 multiplied by 343 equals 20,237. Divided by 31, the result is 652;48. Adding the 5 days and 35 ghatis A ghati is a unit of time equal to 24 minutes elapsed since the first day of the bright fortnight at birth, we get 658;23. Dividing this by 30, the remainder is 28 lunar days in the bright fortnight. In this calculation of the lunar day, one must accept the lunar day on which the previously determined weekday falls, as the weekday is the primary regulator. || 11 ||

Now, the Calculation of the Lunar Mansion (Nakshatra) and Yoga

The elapsed years multiplied by 10 original: "vyomendu," where vyoma=0, indu=1 and subtracted by the quotient obtained by dividing the years by 240 original: "shunyavedashvi," where shunya=0, veda=4, ashvi=2. This result, placed in two positions and added to the birth mansion and birth yoga respectively, then divided by 27 The number of lunar mansions, gives the current mansion and yoga. || 12 ||

Regarding the calculation of the mansion and yoga: "Divided by 27..."—the remainder is the clear result. For example, the elapsed years 59 multiplied by ten is 590. Set this aside. 590 divided by 240 gives a quotient of 2. Subtracting this from the 590 above gives 588. Adding the birth mansion (the 8th, Pushya), we get 596. Dividing by 27, the remainder is 2; this indicates the Bharani mansion has passed. In the other position, 588 added to the birth yoga (the 13th) equals 601. Dividing by 27, the remainder is 7, which is the yoga named Shobhana. || 12 ||
