THE FIRST ARYA-SIDDHANTA, MEAN SYSTEM.
Table LXXVI, ools. 18, 14, 17, shows the day and time of occurrence of mean Meshasankranti (mean sun at long. 0°) in each year, and Example 1 shews how to find the value of a at mean sunrise of that day. To that value must be added from Table LXV the increment of a during the interval from mean sunrise to moment of samkranti. The advance of a during each mean solar month, i.e. from each mean sankranti to the next. (Table LXXVII, col. 4) is 307-3526. The work may be carried out by use of whole numbers, except when a case is very close. This occurs when a waning moon is very near 10,000, or when a waxing moon is very near 0.
Required the above details for the years noted in Examples 1, 2, viz. A.D. 624-5 and 625-6.
In A.D. 624-25 mean Mégha-Ramkrinti took place 14h 2- 30s after mean sunrise. In A.D. 625-26 it took place 20h 15m 0 after mean sunrise (Table LXXVI, cols. 13-17).

eto In A.D. 624-25 it is seen that the mean moon was waning at the Karka-samkranti and Waxing at the Simha-samkrinti, proving an intercalation of a lunar month, which month (soe Table LXXVII, col. 1) was Srivas Actually a at Sitha-sankranti was 58 36.
