XVIII.72 XVIII. STAR-PLANETS 359 (d) The rising and setting are given by observation at different regions and different conditions of the atmosphere, and therefore vary among the siddhāntas. (e) In the case of the inferior planets the degrees should add upto zero. When the degrees are positive and greater than the days, the planet is gaining upon the Sun, and the total gain is its elon- gation. When the degrees are less than the ‘days’, the planet is lagging behind. When the degrees are negative and numerically greater than the ‘days’, the planet is retrograde and comes at the middle of the cycle, if the cycle begins and ends at superior conjunction. Example 2. Compute Mars at 1,20,553 days from epoch. The solar days are, 1,20,553 × 360 ÷ 365-15-30 = 1,18,817.5, and the Sun is 17°.5, taking the sun at epoch as zero, which it nearly is as already shown. 1,18,817.5 − 6329 = 1,12,488.5 1,12,488.5 × 4 ÷ 3075 leaves the remainder 1004. 1004 ÷ 4 = 251, real remainder of ‘days’. During this period we get the movement: − 15° in 56 ‘days’, − 60° in 188 ‘days’, and − 4° for the 7 ‘days’ remaining, total − 79°. Adding − 79° to the Sun, 17°.5, True Mars = 298.5°.

Subtract 14,681 from the ‘days’. Multiply the remainder by 29, and divide out by 3312. Take the remainder and divide by 29. The ‘days’ for Mercury in the cycle is got. 70a. A.विंशशि.
