Turning to Table III. on page 14, we find the remaining quantities, gh. 47, p. 43, that the equivalent, in mean solar days, of 96 shew the time after sunrise, on that Thursday, tithis, is days 94, gh. 17, p. 36.

We are dealing with a northern date and that is why the títhis are counted in this way. If we were dealing with southern date, the enumeration would
be, in Chaitra, 30; in Vaisakha, 30; in Jyêshtha, 80; and in the bright fortnight of AshAdha, 11. The total is the same, 101 ; since a bright fortnight is concerned.
