explanation of the Jyotisha-Veddnga.

when the sum of her progress during the five preceding ayanas is equal to 
5 X 18 x 9 q- nakshatras. And the fact of the sum of her progress at the 
end of each period of 2\ years remaining always the same goes of course 
far to prove the supposed thorough uniformity of her progress ; for what 
should be the inequalities which regularly disappear or destroy each other 
at the end of the stated period ? 
We may therefore assume that the author of the Jyotisha was either 
not acquainted with the irregularities of the course of the moon which are 
taken into account by the later Indian astronomers, viz. the irregularities 
produced by the position and the revolution of the line of apsides of the 
sun and moon, or, at least did not make a practical use of them for his cal¬ 
culations. Keeping this in view, let us now consider a point which was un¬ 
doubtedly of primary importance in the eyes of a vedic Astronomer, viz. 
the question in which points of the circle of the nakshatras full moon and 
new moon are taking place during the whole quinquennial cycle. 
The yuga being assumed to contain 67 periodical lunar (nakshatra) 
months and 62 synodical lunar (chandra) months, one chandra month is 
equal to -£-| = 1 -g- nakshatra months. Consequently, the moon pos¬ 
ing in one nakshatra month through 27 nakshatras, passes in one chandra 
month through 27 +

nakshatras and in one paksha (lunar 
half-month) through 14 nakshatras. Full moon is therefore always 
separated from new moon and again new moon from full moon by the last 
mentioned quantity. On this ground I have drawn up the following list 
giving the places where all the hundred and twenty-four parvans (62 full 
moons and 62 new moons) of the yuga take place. It begins of course with 
the new moon marking the beginning of the yuga, which takes place at the 
beginning of sravishtha or end of sravana. The first column gives the new 
moons, the second one the full moons.
