c7.22

As the years of the 60-year Cycle of Jupiter are only occasionally mentioned in the inscriptions of Northern India, I have not thought it worth while to give the Jyotishtava reckoning in addition to that of the Sûrya Siddhânta. In fact, the difference between the two is never more than one year, and that only between the two periods of omitted years. In the Second Century A.D., the omitted year of the Sûrya Siddhânta reckoning took place in 136, while that of the Jyotishtava was two years later—in 138. In A.D. 394, the omissions took place together. In A.D. 479 the Jyotishtava omitted year preceded that of the Sûrya Siddhânta by one year, but in the present Century the Jyotishtava omitted year, No. 48 in 1848, preceded the other, No. 1 of 1856, by thirteen years. The current years of the two cycles, however, generally correspond, excepting in the short periods between the two omissions, when they differ by only one year. The years 847 and 907 A.D. were initial years of cycles in all three modes of reckoning: and the numbers of all the years coincided from A.D. 825 (the 39th year) down to A.D. 909.
