CHAPTER VII ASTRONOMICAL CONSTANTS Revolutions performed by the planets around the Earth in a period of 43,20,000 solar years (called a yuga): 1-5. The revolution-number (bhagana) of the Sun is 43,20,000; of the Moon, 5,77,53,336; of Saturn, 1,46,564; of Jupiter, 3,64,224; of Mars, 22,96,824 ; of Mercury and Venus and of the sighroccas of the other planets, the same as that of the Sun; of the Moon's apogee, 4,88,219; of (the sighrocca of) Mercury, 1,79,37,020; of (the sighrocca of) Venus, 70,22,388; and of the Moon's ascending node, 2,32,226. Intercalary months, omitted lunar days, and civil days in a yuga: 6-8. The number of intercalary months (in a yuga) is 15,93,336. For the determination of the number of intercalary months elapsed, (this is the multiplier): the diviser is twelve times the number of solar years in a yuga (i.e., 5,18,40,000). The number of omitted lunar days (in a yuga) is 2,50,82,580. (For finding the number of omitted lunar days elapsed, this is the multiplier): the divisor is 1,60,30,00,080 (which is the number of lunar days in a yuga). The number of civil days in a yuga is stated to be 1,57,79,17,500. Intercalary months in a yuga = (lunar months in a yuga) · (solar months in a yuga) = {(revolution-number of the Moon) (revolution-num- ber of the Sun)}- 12×(revolution-number of the Sun) = (revolution-number of the Moon)- 13x (revolution- number of the Sun) = 15,93,336. Omitted lunar days in a yuga (lunar days in a yuga) - (civil days in a yuga) = 2,50,82,580.
