Chapter 8 · Month Chart and Monthly Results
मासप्रवेशादिविचाराध्यायः
योज्याः शोध्या वर्षपालनाडीषु त्रैक्यसंस्कृताः ॥मासवेशे स्फुटा नाड्यो देशान्तरसुसंस्कृताः ॥ २२ ॥
These ghatikas (24-minute unit), corrected by the traikya (the sum of three corrections), are to be added to or taken from the year lord's ghatikas. The exact ghatikas at the month entry are then well corrected by the deshantara (correction for distance east or west).
Simple meaning: Another method: add or subtract the corrected ghatikas to the year lord's ghatikas, then correct for longitude.
त्रैक्यमन्दपनाडीषु सूर्याद्व्यस्तम्प्रकल्पयेत् ॥
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.
