“S 14 Nrsimha caturdasi (pradosa vyapini — if it occurs on two successive days, the second day is to be observed, special when combined with naksatra 'Svati', yoga 'Siddhi' and 'Saturday').” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 102. The row calls the day special with Svātī nakṣatra, Siddhi yoga and a Saturday; none is tested.
