0 = Saturday. 245 = (Table IX.) Sept. 2nd.

Answer.—Saturday, September 2nd, 1848 A.D.

Example xii. Required the week-day and A.D. date corresponding to the South Malayâḷam Âṇḍu 1024, 19th Chiṅgam. (The calculations in Example xi. shew that the South-Malayâḷam month Chiṅgam began civilly one day later (Art. 28, Rule 2b). Therefore the Tamil 20th Âvaṇi was the 19th South-Malayâḷam.)

Referring to Table II., Part ii., we see that the date is the same as in the last example.

Example xiii. Required the week-day and A.D. date corresponding to the North Malayâḷam Âṇḍu 1023, 20th Chiṅgam.

Referring to Table II., Part ii., we see that the date is the same as in the last two examples.

150. Many inscriptions have been discovered containing dates, in expressing which a tithi has been coupled, not with a lunar, but with a solar month. We therefore find it necessary to give rules for the conversion of such dates.

Parts of two lunar months corresponding to each solar month are noted in Table II., Part ii., col. 14. Determine by Art. 119, or in doubtful cases by direct calculation made under Arts. 149 and 151, to which of these two months the given tithi of the given fortnight belongs, and then proceed according to the rules given in Art. 139.

It sometimes happens that the same solar month contains the given tithi of both the lunar months noted in Table II., Part ii., col. 14, one occurring at the beginning of it and the other at the end. Thus, suppose that in a certain year the solar month Mesha commenced on the luni-solar tithi Chaitra śukla ashṭamî (8th) and ended on Vaiśâkha śukla daśamî (10th). In this case the tithi śukla navamî (9th) of both the lunar months Chaitra and Vaiśâkha fell in the same solar month Mesha. In such a case the exact corresponding lunar month cannot be determined unless the vâra (week-day), nakshatra, or yoga is given, as well as the tithi. If it is given, examine the date for both months, and after ascertaining when the given details agree with the given tithi, determine the date accordingly.

Example xiv. Required the A.D. year, month, and day corresponding to a date given as follows;—"Śaka 1187, on the day of the nakshatra Rohiṇî, which fell on Saturday the thirteenth tithi of the second fortnight in the month of Mithuna."^[1]

It is not stated whether the Śaka year is expired or current. We will therefore try it first as expired. The current year therefore is 1188. Turning to Table I. we find that its initial day, Chaitra śukla 1st, falls on 20th March (79), Friday (6), A.D. 1265. From Table II., Part ii., col. 14, we find that parts of the lunar months Jyeshṭha and Âshâḍha correspond to the solar month Mithuna. The Mesha saṅkrânti in that year falls on (Table I., col. 13) 25th March, Wednesday, that is on or about Chaitra śukla shashṭhî (6th), and therefore the Mithuna saṅkrânti falls on (about) Jyeshṭha śukla daśamî (10th) and the Karka saṅkrânti on (about) Âshâḍha sukla dvâdaśî (12th) (see Art. 119). Thus we see that the thirteenth tithi of the second fortnight falling in the solar month of Mithuna of the given date must belong to amânta Jyeshṭha.
