which occurs at the end of every anomalistic cycle, which may be at any time of the day and not necessarily at sunrise At sunrise, say, on the current day, suppose a full days and b part-day have gone by since when the anomaly was last Zero. This ould mear that we can commence using the Caा7dra)valk)'05, one per day, from the moment which is exactly (a+b) days before the current day. Now, let us consider a moment which is b day before the current day. Since b is only a fraction of a day, this Moment will fall in the previous day, its /141-wi7a4f being the s071e as the moment of the end of the cycle a days ago. So, if we add to the Moon's Dl।ruva (Zero correction) at the end of the cycle, the Moon-sentence equal to ८, the result will be the True Moon (Ca11dro-Spluta) for that Momment on the previous day Now, the above argument will apply not only for the end moment of the last cycle, but also for the end-moment of any cycle before that , the corresponding Momments being exactly (1 +b) days+1 cycle, (0-+b) days-+2 cycles, (a +b) days-+-3 cycles etc. before ७१॥rise on the current day, (i.e., the end of the final Kal:#dird, for the current day). Only, for every additional cycle by which the moment is pushed backwards , a zero-correction of 30-4'-72#', which is the D}}॥१५॥४0 for one cycle, will have to be deducted For mine such previous Zero anomalies (by the reckoming of which one full series of 248 days and 248 Ca71dravakya.s would be exhausted), True Moons can be obtained at nine Momments on the day previous to the current day, i.e., the last day of the Kalidind. The intervals between consecutive Monents will be a little more than 6 1alkds, and a quarter thereof, for which the longitudes could be calculated by the rule of three, would be about 40 minutes. If the true Moons at the nine Momments are required for the current day and the succeeding days, they could be had by adding the succeeding relevant Caा71drovakya in place of the vaky0 first used. For this reason, when the Momments, Vakya.s and True Moons for any day, during a 248 day period, have been calculated and duly entered in a Table, the Tables for the further days could be prepared with ease therefrom It is to be m७ted here that this method depends on the accident that an anomalistic cycle does not consist of a whole number of days,
