8. CALENDRICAL YUGA SYSTEM
The quinquennial yuga or cycle was prevalent in various schools of India, as it was in Jaina school. But, it began with Abhijit. In a cycle of five years there are 60 solar months, 61 stu months, 62 lunar months, 67 nakşatra months and 57 intercalary months. Now one solar year is of

366 days, one piu year is of 360 days, one lunar year is of 354
days,
one nakşatra year is of 327 2
days and one intercalary lunar year is of
383 days 210 muhūrtas. Thus all these years will simultaneously begin and close once in a cycle of 156 cycles of 5 years each, because 156 x 5 years will make 780 solar years, 793 ștu years, 806 lunar years, 871 nakşatra years and 744 intercalary lunar years, 125
Thus the yuga of 285480 days corresponds with the cycles of the following years :
366 x 780 = 285480 solar 360 x 793 = 285480 stu
the following products
