Calends

The calends or kalends () is the first day of every month in the Roman calendar. The English word "calendar" is derived from this word.

== Use == The Romans called the first day of every month the calends, signifying the start of a new lunar phase. On this day, the pontiffs would announce the number of days until the next month at the Curia Calabra; in addition, debtors had to pay off their debts on this day. These debts were inscribed in the kalendaria, effectively an accounting book.
