Brihat Parashara Hora Shastra
मासादि तन्मितं ज्ञेयं जन्मतः प्रक् निषेकजम्। यद्यदृश्यदलेङ्गेशस्तदेन्दोर्भुक्तभागयुक्॥ २८॥
The resultant product in Rāśis, degrees etc. will represent the months, days etc., that elapsed between Nishek and birth. At birth, if Lagn Lord is in the invisible half (i.e. from Lagn cusp to descendental cusp), add the degrees etc., Candr moved in the particular Rāśi, occupied by her, to the abovementioned product.
