“The sukla caturthi in each month is called Ganesa caturthi or Vinayaka caturthi. It is observed at madhyahna. The chief among them are caturthis of Bhadrapada and Magha. Similarly the krsna caturthi in each month is called Sankasta caturthi, to be observed on the day when the tithi is current at moonrise. It is called Angaraka caturthi if it falls on Tuesday.” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 108.
