211 MIDNIGHT DAY-RECKONING day-reckoning too, all this is found to occur: the difference that exists is being stated (below). The next fourteen stanzas relate to the midnight day-reckoning of Aryabhata I. Civil days and omitted lunar days in a yuga and revolution- numbers of Mercury and Jupiter : 22. (To get the corresponding elements of the midnight day-reckoning) add 300 to the number of civil days (in a yuga) and subtract the same (number) from the number of omitted lunar days (in a yuga); and from the revolution-numbers of (the sighrocca of) Mercury and Jupiter subtract 20 and 4 respectively. Thus according to the midnight day-reckoning, civil days in a yuga= 1,57,79,17,800, omitted lunar days in a yuga- 2,50,82,280, revolution-number of the sighrocca of Mercury 1,79,37,000, revolution-number of Jupiter= 3,64,220.. Diameters of the Earth, the Sun, and the Moon: 23. (In the midnight day-reckoning) the diameter of the Earth is (stated to be) 1600 yojanas; of the Sun, 6480 (yojanas); and of the Moon, 480 (yojanas). Mean distances of the Sun and the Moon : 24. The (mean) distance of the Sun is stated to be 689358 (yojanas); and of the Moon, 51566 (yojanas). Longitudes of the apogees of the planets : 25. 160, 80, 240, 110, and 220 are in degrees the longi- tudes of the apogees of Jupiter, Venus, Saturn, Mars, and Mercury respectively ¹. ¹ Cf.
