Chapter 8 · Month Chart and Monthly Results
मासप्रवेशादिविचाराध्यायः
त्रैक्यमन्दपनाडीषु सूर्याद्व्यस्तम्प्रकल्पयेत् ॥देशांतरस्य संस्कारं कुर्याद्व्यस्तम्पलेषु च ॥ २३ ॥
In the traikya (the sum of three corrections) and the 'mandapa' ghatikas (24-minute unit), one should set the correction reversed from the rule for the Sun. The deshantara (correction for distance east or west) correction should also be made reversed, in the palas.
Simple meaning: Another method: the corrections are applied the opposite way to the Sun rule.
अथ त्रैक्यदेशान्तरादिसंस्काररहितेनाहर्गणोत्थस्फुटरविणा अंतरं कर्तव्यन्त्रैक्यसंस्कारो नाडिकासु कर्तव्या ॥ मासप्रवेशवारार्थं जन्माहर्गणोत्थं प्रतिमासं त्रिंशत्रिंशद्युतः कर्तव्यः ॥ एवमुभयप्रकारेणापि मासप्रवेशवारादिकं सममेव भवति ॥
Another method: take the difference with the uncorrected Sun, correct the ghatikas by the traikya, and add 30 days for each month. Both ways give…
अथ संख्यारूपविवर्जिता ॥ तत्तुल्यं दिनकोष्ठस्थफलेन सहितो रविः ॥
For a day entry: take the day number less one, add the table result to the month's Sun, and work out as before.
मुक्तावल्याञ्च ॥
Day entries are worked out the same way for very fine results; this is the teacher's view.
