Origin and meaning 

The Kalends were the first day of the Roman month, when people usually performed their payments. There were also idus ( gone , in Portuguese, meaning ” mid “) and ninth (originally days when the moon was in the middle of its crescent phase). Since “kalendae” did not exist in the Greek calendar, referring to “Greek calendars” is a way of saying “never”.

The expression “ad kalendas graecas soluturos” (“those who intend to pay in Greek calendars”) is attributed by Suetonius , in Vida dos Césares , to the emperor Augustus , who would have used it frequently to indicate those who did not intend to pay their debts.
