When the same shraddha tithis occurs twice in a given month, shraddham must be performed during the second tithi and the first tithi is called soonya tithi. If the second tithi is tainted, for example, if it is associated with a period of eclipse or sangramanam, it is considered to be tainted. In such instances, the first tithi must be treated as the shraddha tithi and the second tithi will be termed soonya tithi.
Atithi is referred to pervasion of afternoon period. This is best explained through an example. Srimad Villivalam Azhagiyashingar has explained this with examples in the annexure of his “Ahnikam” – please refer to the same.
