Phaladeepika
तृक्षस्य गम्या घटिका दशाब्द- निघ्ना नताप्ता स्वदशाब्दसंख्या । रूपैर्नगैः संगुणयेन्नतेन हृतास्तु मासा दिवसाः क्रमेण ॥ ३॥
At the time of birth, find out the number of Ghatikas, etc., still to be traversed (by the Moon) in the star he is in. Multiply this by the number of years allotted to the ruler of the star and divide the product by 60. The quotient will be the period in years still to elapse. Any remainder remaining may be converted into months by multiplying by 12 and dividing by 60 and the remainder again into days by multiplying by 30 and dividing by 60 and so on.
