Etymology: The Romans named the calendar after a shout. Their word "kalendae" meant the first day of the month, and it came from "kalō", a verb meaning to call out solemnly. Priests would proclaim the sighting of the new moon, which marked the start of the month, so the day took its name from the announcement itself. From "kalendae" the Romans made "calendarium", an account book, probably because debts and interest fell due on the kalends. That word passed through Old French "calendier" into Middle English as "kalender", and the modern spelling settled later. English already had a native term, "rīmbōc" in Old English, literally a book of reckoning, but the borrowed word eventually replaced it. The two forms, "calendar" and "calendarium", are doublets: one came through French and one was taken straight from Latin.
