12 MEAN LONGITUDE OF A PLANET adhimāsaseṣa lunar days in a yuga The fraction of the omitted lunar day (obtained in the rule) avamasesa or ähnika lunar days in a yuga = avamasesa civil days in a yuga avamasesa × 60 civil days in a yuga' in mean solar months. in mean civil days. in mean lunar days. in mean lunar ghatis. The fraction of the intercalary month corresponding to the above fraction of the omitted lunar day (intercalary months in a yuga) × (avamasesa) (lunar days in a yuga)×(civil days in a yuga)' in mean solar months. (3) Adding (1) and (3) and multiplying by 30, the total fraction of the intercalary month adhimāsasesa lunar months in a yuga + (intercalary months in a yuga) x (avamasesa) (lunar months in a yuga) × (civil days in a yuga) in mean solar days. (4) Suppose that m lunar months and d lunar days have elapsed since the beginning of Caitra. Then, treating them as mean lunar months and mean lunar days, m months and d days denote the time elapsed since the beginning of mean Caitra up to the beginning of the current lunar day (treated as mean lunar day). As (2) is the interval, in mean lunar ghatis, between the beginning of the current lunar day and the mean sunrise on that day, therefore m months + d days + (2)
