EPIGRAPHIA INDICA.
Bs. 4. Samvat 1154, Chaitra-sudi 2, Ravau (southern year), Samvat 1154 =4199 K.Y. Chaitra belonging to the corresponding solar year, K.Y. 4198, we use the second Chaitra of Table III (see 16).

(*) 2:09 763, eq.=0. The 2nd titki ended on the preceding day, Sunday, as required. Ex, 5. Samvat 1194, Chaitra-badi 5, Gurau. Northern year, pérnimanta. We must use the second Chaitra of Table III (see $ 15). Samvat 1194 4238 K.Y.

19-26 Thus the 20th titki, or 5th titki of the dark fortnight, ended on Thursday as required.
If a doubt be entertained, whether the tithi actually ended on the day whose tithi has been calculated, calculate for the following day; thus
4238 K. Y. (1) 2.82 427 10th Chaitra (6) 17.44 412
(6) 20-26 889 ('s an, 839, eq. = 0.07
20-33 Hence at the beginning of Friday (6) the 21st titki was running, and therefore the day could not be badi 5.
We may however dispense with a second calculation whenever the running tithi is between 10 and 90.
27. Corrections for true time. The tables yield the date in mean Lanka time; to convert it into mean local time, add to or subtract from it the difference in time between the prime meridian—that of Ujjain, or 75° 51' 45' (5 hours 3 minutes 27 seconds) east of Greenwich, -and the place from which the document is dated, one degree being equal to 6 rinádís. If the place lies to the east of Ujjain, the amount must be added ; if to the west, it must be subtracted, for local time. Table XXV furnishes, for the principal towns in India, the latitudes, longitudes, and difference in time expressed in ghaţikás and palas. The sign + or - indicates the amount that is additive or subtractive.
28. A second correction (the Equation of time) is required for converting mean local time into trae local time. A method for finding the exact value of this correction will be given below. For the present it will be sufficient to know in which way the correc. tion influences the date. The rule is that true local time is in advance of the mean time i.e. the correction is additive) from about solar Vaisakha to Karttika, but behind it (or subtractive) from about Kárttika to Vaisakha. The correction is at its maximum about the ends of solar Ashådha and Pausha, and at its minimum about the beginnings of Vaisakha and Kårttika.
29. To find the beginning of a solar month.-Whenever new-moon occurs on one of the three first days of a solar month, viz. on one of the three days marked 0, 1, 2, in the
