Surya Siddhanta
ग्रहवद् द्युनिशे भानाम् कुर्याद् दृक्कर्म पूर्ववत् । ग्रहमेलकवच् छेषम् ग्रहभुक्त्या दिनानि च॥
As in the case of the planets, calculate the apparent longitude (dåkkarma) according to the measures of day and night. For other planets, use the rule for conjunction. It will suffice to divide by the daily motion of the planet (grahabhukti) instead of the difference in daily motion (bhuktis).
english translation
grahavad dyunize bhAnAm kuryAd dRkkarma pUrvavat । grahamelakavac cheSam grahabhuktyA dinAni ca॥
