154 CORPUS INSCRIPTIONUM INDICARUM, VOL. III.
Now, however, we have to determine the spashṭa-tithi, or apparent tithi. For this
purpose, we require the parâkhya-correction, which is to be ascertained through the tithi-
kêndra.
Turning again to Table III. p. 14, we find that the variation in the tithi-kêndra
for 96 tithis is tithis 12, gh. 1, p. 20. Enter this in (c), below tithis 22, gh. 18, p. 35,
which we have already arrived at as the tithi-kêndra at the end of Chaitra śukla 6. Add
the two quantities together; and the result, — excluding 28 tithis, as before, — is tithis 6,
gh. 19, p. 55; which is the tithi-spashṭa-kêndra at the end of the given tithi, Âshâḍha
śukla 12.
With this argument, we turn to Table IV. p. 20, for the parâkhya-correction. In
this Table, the correction is given for tithis and ghaṭîs, at intervals of ten ghaṭîs. Thus,
for the tithi-spashṭa-kêndra, tithis 6, gh. 10, the parâkhya is gh. 24, p. 10; and for tithis
6, gh. 20, it is gh. 24, p. 19. The difference, 9 palas, is shewn in the last column of the
Table, and would serve to calculate the exact parâkhya for the tithi-spashṭa-kêndra. But
here it is sufficiently close for our purposes to take the parâkhya as gh. 24, p. 19.
Under (a) the abdapa, enter this parâkhya below the sum of the tithi-bhôga and the
solar equivalent of 96 tithis, and, — as is indicated by the sign plus at the top of col. 1 in
Table IV., — add it to that sum.
The result, vâras 95, gh. 47, p. 43, gives the number of days, and parts of a day,
that had elapsed, from sunrise on the day of the Mêsha-Saṁkrânti, up to the end of
the apparent Âshâḍha śukla 12. To the days, 95, add 1, the week-day of the Mêsha-
Saṁkrânti. Divide the sum, 96, by 7, and the result is 13 weeks, and 5 days over; which
shews that the current week-day of Âshâḍha śukla 12 was the fifth day in the week; that
is Thursday. The remaining quantities, gh. 47, p. 43, shew the time after sunrise, on
that Thursday, on which the given tithi, Âshâḍha śukla 12, ended.
The Tables in Prof. K. L. Chhatre's book, however, are adapted to the meridian
of Bombay. The ghaṭîs and palas, therefore, of a tithi worked out by the method ex-
hibited above, are for Bombay; and are to be reckoned from mean sunrise at Bombay.
When the tithi is required for any other particular place, the difference of longitude in
time (one degree = ten palas) is to be added or subtracted, according as the place is east
or west of Bombay. In the present instance, as I learned after first working it out, the above
Śaka date was selected in consequence of its being the equivalent of the date, in Gupta-
Saṁvat 165, recorded in the pillar inscription of Budhagupta at Êraṇ in the Central
Provinces. We have therefore now to determine the tithi for Êraṇ itself. The longitude of
Bombay is 72° 51'; and that of Êraṇ is 78° 15'; both east of Greenwich. Êraṇ, therefore
is 5 degrees, 24 minutes, east from Bombay. Adding (5° 24' × 10 =) 54 palas to 47
ghaṭîs and 43 palas, which we have obtained above for Bombay, the tithi at Êraṇ is
gh. 48, p. 37, reckoned from mean sunrise on the same day, Thursday.
