Suppose there is a Shraddha on the marriage day. Second Kanda 235 How should sthalipaka be done? Divide the duration of the night by thirty. Omit the last two parts. Just before the last two parts, in the 28th part the sthalipaka homa should be performed, if it is not an amavasya (new moon night, the 30th tithi). If the day is an amavasya and if the woman has no child, the Darsa homa should be gone through and also on the day of the solar ingress.
