month. From what is known about the general constitution of the yuga

this quantity is of course readily found to be equal to 66 + — + 



62 



——^ — - The commentator calculates this quantity as follows. If the 

 62 X 67. i- J 



sun performs during 124 parvans five complete revolutions, how mucli does he 

 perform during 2 parvans ( = one synodical month) ; answer : =

— rev. This therefore is the excess of the synodical mouth above the

periodical one. In order that the division can be carried out, the — rev.

are tui-ned into nakshatras by multiplying them by (i. e. by 27 --, 



the duration in ahoratras of the periodical month or, if we like, the 



extent of the nakshatras ; 27 entire nakshatras j^lus the fractional nak-

shatra Abhijit). Result of the multiplication ■ . Again — in order to 



turn tlie days or nakshatras into muhiirtas — the numerator is multiplied 

 27-1500 



by 30. Eesult = — mr— . This division being performed gives as result 



4154 ° ^ ^ 



66 muhiirtas. The remainder 336 is multiplied by 62 and the product

again divided by 4154. Eesult = — mu.hiirtas. The remainder — 62 — 



should again be multiplied by 67 (the fractions employed being through- 

 out sixty-seconds and sixty-sevenths) and divided by 4154 ; but 4154 

 being itself = 62 x 67, it is seen at once that the result is 1. Thus the

whole quantity is 66 + — + ^ muhiirtas. If now the place of 



the moon at any amavasya or piirnamasi is wanted, the above quantity 

 has to be multiplied by the number of the parvan ; for instance, by one if 

 the moon's place at the first full moon after the beginning of the yuga is 

 wanted. The product shows how far the moon at the time has advanced be- 

 yond the place she had occupied at the beginning of the yuga, if full moons 

 are concerned, or beyond the place she had occupied at the new moon preceding 

 the beginning of the yuga, if new moons are concerned, (the new moon im_ 

 mediately antecedent to the beginning of the yuga having been selected 

 as starting-point for all calculations concerning new moons). So far the 

 place of the moon is expressed in muhurtas only ; now in order to find 

 from these the nakshatra in which the moon stands at the time, we should
