Note 192 — Chapter IX
William Johnston translation
Four different kinds of years occur in some of the ancient Grantham or Samscred books. One consists of 355, another of 365, the third of 360, and the fourth of 324 days. Besides these, there is also the year of Saturn, or Shani, which always completes its course in twenty-nine years and six months. Likewise the year of Jupiter, or Brahaspadi, which consists of 360 days, divided into ten months. In some of the Indian provinces the people still reckon by these years. This variety, in determining the revolutions of the planets, seems to shew that the Brahmans and Samanæi were diligent observers of the heavens in very ancient periods. The orbits of the planets are divided into a certain number of Yògiana, each of which is equal to a mile. A.
