Reference

CRC 1955, p. 102

S 2 Rathayatra (paraviddha, special when combined with naksatra 'Pusya') Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 102.

Here noon or madhyahna relates to the period of time from 24 minutes (one ghatika) before mid-day upto the same time after it. This is the most appropriate time. If this time is not covered by the tithi on any day, the festival is to be observed on the succeeding day of the tithi. Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 101.

The row calls the day special with Puṣya nakṣatra; the nakṣatra is not tested.
