Dies fasti

Extracted from the Wikipedia article Fasti.
Public business, including the official business of the Roman state, had to be transacted on dies fasti, "allowed days". The fasti were the records of this business. In addition to the word's general sense, there were fasti that recorded specific kinds of events, such as the fasti triumphales, lists of triumphs celebrated by Roman generals. The divisions of time used in the fasti were based on the Roman calendar.
