ग्रहराशिस्वरूपवर्षप्रवेशाद्यानयनाधिकारः
अत्र जन्मार्कतुलो रविर्यस्मिन्मासे भवति तस्मिन्नेव मासे वर्षप्रवेशो ज्ञेयः ॥
Here is a point to know. The year's entry falls in the very month in which the Sun equals the birth Sun.
Simple meaning: Month of the year entry: the month in which the Sun returns to its birth place.
उक्तंच ॥
Month of the year entry: the almanac month where the Sun equals the birth Sun.
तत्र जन्मार्कसमो रविर्यदि जन्ममासे नायाति परे पूर्वे वा मासे आयाति तदा जन्ममास एकरहित एकयुक्तो वा कर्तव्य इति ॥
Month shift: if the Sun matches in the month before or after, move the birth month back or forward by one.
अथ वर्षध्रुवकोपपत्तिः ॥ अत्र वर्षादिः साध्यस्सच सौरएव ॥
Proof of the year figure: the year counted here is the solar year.
