It will be seen that for all ordinary purposes it will suffice to tie a constant 2d. 4h. 9m.; but for very close work take the sodhya-value at K, Y. 3601, A.D. 500, as being 28. 4h. 8m. 54-5828. and add for every succeeding 100 years 2.117s, and for 1000 years 21.168s.
RULE FOR WORK, AND EXAMPLE. 229. All work formerly necessary for the purpose of ascertaining which Jovian samvatsara began in the course of any given year according to any of the principal Siddhāntas, and whether calculated by apparent or mean Mēsha samkrānti, is now obviated by the information given in Table XLII below, which solves tha question at a glance. It shews the samvatsara current at every M&sha sathkranti, and we therefore know that the next samvatsara of the cycle began during the year. When there is an asterisk shown it means that this latter samvatsara both began and ended during the solar year, so that the next again also began during that year and was current at Masha sankranti of next year.
230. But we sometimes desire to know the time of beginning and ending of a samvatsara in order to ascertain whether it was current at the time of the event or action chronicled in an inscription.
231. This time is precisely the same whether we calculate from mean or from apparent Mēsha samkrānti, and as the time of the latter is already given in, or can be gathered from, cols. 13 to 17 or 17a of the Indian Calendar, it is easiest to use that information as basis of work. Find this required time, therefore, according to the Sürya Siddhanta (with or without the bija), the First Arya or Aryabhatiya, the Original Surya, and Brahma Siddhantas, and the Siddhānta Siromani in the manner described in $$ 146, 147, 153, 158, 162 or 167 A and examples 48 to 59 A of Indian Chronography.
232. The work according to the Second Arya Siddhanta is precisely similar, but we have to zase the Tables A A and B B in the text above instead of any of the other Tables in the text of Indian Chronography. I proceed with an example.
233. We want to know what samvatsara began in K. Y. 4380 expired, A.D. 1279-80 according to the Second Arya Siddhanta. The answer is given by Table XLII below. 18 Tāraṇa was current both at apparent and mean Mēsha sankrantis, and therefore in either caso gave its name to the solar year; 19 Pārthiva began in the course of the year.
When did Parthiva begin ? and when did it end?
For rough work the following will always suffice, whether we have been calculating by mean or apparent Mēsha sankranti, the time being the same by both. We will work by
