CRC 1955, p. 103

“K 8 Janmastami (madhyaratra-vyapini), if midnight is covered on two days, or not on any day, it is to be observed on the 2nd day; special when combined with naksatra 'Rohini' at midnight, more so when on Monday or Wednesday. If the combination occurs before midnight and 'Rohini' extends up to midnight, it is to be observed on that day. Gokulastami.” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 103. The clauses on Rohiṇī nakṣatra, the Vaiṣṇava observance on the day after saptamī, and the Assam and South India reckoning in the solar month belong to other readings and are not applied.
