“The krsna caturdasi in each month is called 'Sivaratri'. The chief among them is that of Magha. The tithi must cover nisitha (or pradosa in some opinion).” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 108. The alternative opinion that reads pradoṣa instead of niśītha is not evaluated.
