﻿274 0N ™ E ASTRONOMICAL COMPUTATIONS 



As the»solar months in a Yug, 51840000, are to the 

 intercalary lunar months in thatqcle, 1593336, so 

 are the solar months 23470618687, to their corres- 

 ponding intercalary lunar months 72 1384677 ; which 

 added together, give 24192003364 lunations. This 

 number multiplied by thirty produces 725760100920 

 tifhis, or lunar days, from the creation to the new 

 moon in Cart'ic. ; to which add fourteen tifhis for 

 the same, to the purmma tifhis in thai month 

 725760100034. Then, as the number of tifhis in 

 a Yog, 1603000080, is to their difference exceeding 

 the mean solar days in that cycle (called cshaya 

 tifhis) 25082252, so are 725760100934 tifhis, to 

 their excess in number over the solar days 1 135601 7987, 

 which subtracted, leaves. 714404082947, as the num- 

 ber of mean solar days from the creation, or when the 

 planetary motions began, to a point of time which 

 will be midnight under the fir ft meridian of Lanca, 

 and near the time of full moon in Cartic*. The 

 first day after the creation being Ravi-var, or Sun- 

 day, divide the number of days by seven for the day 

 of the week, the remainder after the division being 

 two, marks the day Soma-var, or Monday. 



SECOND OPERATION. 



For the mean longitude of the sun, moon, and 

 the ascending node. Say, as the number of mean 

 solar days in a Malm Yug is to the revolutions of 

 any planet in that cycle, so are the days from the 

 creation to even revolutions, which reject, and the 

 fraction, if any, turned into sines, &c is the mean 

 longitude required.

 Bengal style, and with the month of OBohcr or November (here- 

 after to be determined) in the year of Christ 1789,
