For knowing the sankrantis (the Sun's entry into a sign), here are verses of the revered astrologer Rama. He is the crown jewel of astrologers, emperor of all reckoners, and our guru. Take the Shaka (Indian era) year less 1529. Put it in three places: with a quarter added, halved, and with a half added. Add 0, 48 and 20 to them in order. Cast it out by two. This gives the Aries sankranti.
Simple meaning: Aries sankranti: Shaka year less 1529, worked in three places like the year figure, plus 0, 48 and 20.
मे | वृ | मि | क | सिं | क | तु | वृ | ध | म | कुं | मी | राशी
Sankranti table: how much weekday, time and tithi to add to the Aries sankranti for each sign.
अथैकस्मिन्मेषसंक्रान्तौ ज्ञातायां तदग्रिमसङ्क्रान्तिज्ञानार्थं सूत्रम् ॥
Next sankrantis: add these days and ghatikas to the Aries day, Taurus first.
अथ संक्रांतितिथिज्ञानोपायः ॥
Tithi of the Aries sankranti: Shaka year less 1529, times 11, 3 and 53 in three places, plus 11, remainder by 30.
