My mothers srardham falls on the Soonya Thithi. When should I perform the srardham as normally srardham is not performed on the Soonya thithi.

Answer: If there are two thithis falling in a month, then one is taken as Soonya thithi. There ought to be another thithi if one thithi is mentioned as Soonya. Depending on its merrit, it can be at the beginning or end of a month the soonya thithi may fall; so one has to take the other thithi which is not mentioned as soonya. Rarely in some cases, during Margazhi month, if the thithi is not given, then it ought to be performed in the following month on the same thithi. When thithi Dwayam (two thithis falling on the same day), in cases, the earlier or later date can be shown as Adhika thithi as athi-thithi; But wherever it is mentioned as Soonya thithi, normally there will be another day, either at the end or on the beginning of the same month.
