मासप्रवेशादिविचाराध्यायः
अस्य प्रस्फुटता प्राग्वत्सूक्ष्मोर्कस्स्यात्परिस्फुटः ॥उक्तरीत्या स्फुटः कार्यो जन्मार्कोऽपूर्व एव हि ॥ ११ ॥
Its exactness is made as before; the fine Sun becomes fully exact. The birth Sun should also be made exact by the method told, as something new.
Simple meaning: The true Sun is made as before. The birth Sun is made true the same way.
प्रतिवर्षं स एवार्कस्स्फुटस्सगतिको भवेत् ॥
The year Sun is the exact Sun. A month's Sun is the year Sun plus one sign for each month.
स्फुटार्काः स्युर्द्वितीयादिमासेष्वर्कास्तु मासजाः ॥
From the second month, each month's Sun is the exact Sun. For days, add one degree a day.
अथ स्वाभीष्टमासस्य संख्यारूपविवर्जिता ॥
For the month's Sun: take the chosen month number less one and add the table result for it.
