As per the books there are ten days of asaucam for gynatha-s upon a spinster’s demise. From what we heard elders have observed three-days asaucam for the demise of unmarried women. For a spinster’s demise, the brother needs to observe three days of asaucam and that applies to the wife as well.
A married son should observe three-days asaucam and a married daughter should observe one and a half days asaucam for their aunt, respectively. Asaucam is over by just taking a head bath for an unmarried daughter or son upon the demise of their aunt.
