“K 14 Mahasivaratri (nisithavyapini) — In some opinion it is to be observed on nisitha and in some opinion on pradosa. If occurs on two successive nisithas then according to Hemadri it is to be observed on the first day and according to Madhava, to be observed on the second day” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 105. The alternative opinion that reads pradoṣa instead of niśītha is not evaluated.
