In the Gupta year 199, corresponding to the expired year 3619 of the Kaliyuga, a month by the rules of mean intercalation would have had to be intercalated before the month Kârttika. Judging from other dates, I consider it highly probable that in the period to which our date belongs the rules of mean intercalation were observed, and that moreover a month, by those rules intercalated before the proper Kârttika, would have received its name from the preceding month Asvina. Assuming this to have been actually the case, the Gupta year 199 would have contained only one month called Kärttika, and the month Kârttika which is put down in the date would be the ordinary Kârttika of our Tables. But the possibility is not excluded that the intercalated month might have been called Kårttika too, and in that case the term Kârttika of the date might be taken to denote either the first Kârttika (which would be the month Âśvina of our Tables) or the second Kârttika (s.e. the ordinary Kârttika of the Tables).

At first sight, another difficulty is presented by the circumstance that in line 3 of our record the tithi of the date is simply described as 'the tenth tithi of the month Kârttika' (Karttikamasa-dasami), without any indication as to which lunar fortnight the tithi must have belonged to. But this difficulty, in my opinion, is removed by the fact that at the end of the record, where the date is repeated in figures, the same tithi is described by the expression Kârttika-di 10. In the Khôh plates of Samkshobha of the Gupta year 209 (Gupta Inscr. p. 114) we find the tithi described, in lines 2 and 3, as Chaitramása-suklapaksha-trayôdast, and in line 24 as Chaitra-di 28; and in the Majhgawâm plates of Hastin of the Gupta year 191 (ibid. p. 107), in line 2 as Mághamasa-bahulapaksha-tritiya, and in line 20 as Mágha-di 3. The manner in which the Khôh plates are dated has been taken to prove that the month Chaitra of those plates was the purnimanta Chaitra; and the dates of both records indicate that it was the custom to quote, when a date was repeated in figures, the number of tithis elapsed since the commencement of the month, irrespectively of the lunar fortnights. Applying this to the date under discussion, we conclude from the statement Kárttika-di 10 that since the commencement of the purnimanta Kârttika there had elapsed 10 tithis, or, in other words, that the tenth tithi of the month Kârttika, quoted in line 3, was the 10th tithi of the first or dark half of the purni mânta Karttika (the Kârttikamasa-bahulapaksha-dasami).
From what has been stated above, it follows that the tithi of our date is the 10th tithi of the dark half of, probably, the purnimanta Kârttika of our Tables, but that possibly it may be the 10th tithi of the dark half of the purnimanta Âévina of the Tables. On the first alternative the date would correspond to Monday, the 15th October A.D. 518, when the 10th tithi of the dark half of the purnimanta Kârttika ended 8 h. 26 m. after mean sunrise; on the second alternative to Saturday, the 15th September A.D. 518, when the 10th tithi of the dark half of the purnimanta Asvina (i.e., possibly, the first purnimanta Kårttika) ended 13 h. 36 m. after mean sunrise. It will be shown now that, in either case, the Jupiter's year in which the date fell was a Maha-Margasirsha year, as required by the wording of the original date.
The late Mr. S. B. Dikshit has fully explained that a Maha-Margasirshal year occurs when Jupiter at his heliacal rising (i.e. his first appearance in the morning after his conjunction with the sun) is in either of the nakshatras Mrigasiras and Ardrâ, i.e., when at his heliacal rising his true geocentric place (or trae longitude), according to the equal space system, is between 53° 20' and 80°, according to the Brahma-siddhanta between 52° 42' 20" and 72° 28' 12.5", and according to Garga between 53° 20' and 73° 20'. Now in the time immediately preceding the 15th September (and the 15th October) A.D. 518 Jupiter was in conjunction with the sun at mean sunrise of the 11th May A.D. 518, when his own true longitude was 51° 3', and that of the
