28 How do we know that the lunar month to be suppressed is Pausha and not any other? Because that is the first new moon which we are unable to place before a sankrânti. We find that Mâgha and Phâlguna are each followed by a sankrânti, though a long way off, and between the sankrântis at 334·9053 d. and 365·2587 d. there are again two new moons, that is to say Chaitras, the first of these being adhika and the second nija. Here also we note that appearances are deceptive, for the mean new moon at 334·8346 is apparently a Phâlguna, but the calculation of the anomalies shows it to be an adhika Chaitra.
