ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
अथवर्षप्रवेशवेलानयनम् ॥ तत्साधनमुक्तं यादवेन ॥शको वर्तमानो जनुःशाकहीनो गताब्दा भवेयुश्चतुर्धा निधेयाः॥ध्रुवा १ बाणचंद्रे १५ रिलारामतुल्यै ३१ र्नभःपावके ३०स्ताडितास्ते विधेयाः ॥
Now, finding the time of the year's entry. Yadava has given the way to work it out. Take the current Shaka (Indian era) year. Take away the Shaka year of birth. That gives the years gone. Put them down in four places. Multiply them by the dhruva (fixed yearly figure) numbers 1, 15, 31 and 30.
Simple meaning: Year entry time: years gone (this Shaka year less the birth Shaka year), set in four places, times 1, 15, 31 and 30.
जन्मवारघटिकापलयुक्ताः षष्ट्युपर्य्युपरिगंदिवसाढ्यम् ॥
Year entry time: add the birth weekday and time, carry the sixties, divide by 7. The remainder gives the weekday and time.
अत्रैव सुगमोपाय उक्तो दैवज्ञचक्रचूडामणिभिरस्मद्गुरुज्येष्ठभ्रातृभिः श्रीमन्नीलकण्ठदैवज्ञैः ॥
Same verse as Tajika Nilakanthi 1.16; see its meaning there.
प्रकारान्तरमुक्तं ग्रहज्ञाभरणे ॥
Another way: years gone in three places, plus a quarter, halved, plus a half; add the birth weekday and time.
